News Diamondbacks Team Notes

The Diamondbacks have been one of the better teams in baseball in recent years. The won the NL pennant just two years ago, and last season put together a strong 89-win campaign that just barely missed the playoffs due to a three-way tiebreaker with the Braves and Mets. After an offseason where the club brought in Josh Naylor and Corbin Burnes among a handful of other additions, it wasn’t hard to see the Diamondbacks serving as the main challenger to the Dodgers in the NL West, or at least as an early favorite for one of the NL Wild Card spots.

Things haven’t worked out that way, however. The Diamondbacks entered play today with a 28-31 record that leaves them in fourth place in the NL West, 7.5 games back of the Dodgers but also behind the Padres and Giants. Even in the NL Wild Card race, Arizona is five games back, in line with the records of likely sellers in other divisions like the Nationals and Reds. While they entered the season with a 60.4% chance to make the playoffs according to Fangraphs, today’s playoff odds give them just a 27.9% chance to play in the postseason this year. Those odds are a worrying sign, but they’re hardly the be-all and end-all; the Tigers (20.3%) and Mets (9.8%) both had slimmer odds at the postseason than that one year ago today and ended up not only making the playoffs but playing fairly deep into October.

What separates Arizona from last year’s surprise contenders, however, is that they clearly appear to be on the downswing. Burnes is having elbow troubles, leaving his future at the top of their rotation uncertain at best. Closer A.J. Puk is on the 60-day injured list with an uncertain timeline*. Zac Gallen hasn’t looked like himself all season, and Brandon Pfaadt was having trouble staying consistent even before he gave up eight runs without recording an out in his most recent start against the Nationals. An offense with players like Corbin Carroll, Geraldo Perdomo, Ketel Marte, and even Pavin Smith all hitting incredibly well feels as though it should be a slam dunk to make the postseason, but the club just doesn’t appear to have enough pitching to make a run as presently constructed without significant turnarounds from players like Gallen.

An argument could be made, however, that with Marte nearing the end of his prime years and players like Gallen, Naylor, Merrill Kelly, and Eugenio Suarez ticketed for free agency this winter, that the Diamondbacks would simply be best served supplementing the current roster with more pitching this summer and attempting to make a late-season run. A number of interesting arms could potentially be available this summer, ranging from mid-rotation pieces like Zach Eflin and Nick Martinez to relief help like Pete Fairbanks and Kyle Finnegan. Any of those options could help stabilize the pitching staff enough for Arizona’s vaunted offense to carry the rest of the load, and that’s before considering the unlikely but still feasible possibilities that teams like the Astros and Cardinals decide to dangle Framber Valdez and Ryan Helsley.

The complication with that, however, is that Arizona is already in very uncharted waters when it comes to payroll. Efforts to trade Jordan Montgomery to free up payroll space this winter were unsuccessful, and the fact that he ended up going under the knife before the season began put a stop to any hopes of moving him to make room for other players in the budget this summer. It’s at least theoretically possible ownership could be willing to green-light even more spending for a squad that RosterResource suggests is already costing the club $196MM this year, but it would hardly be a surprise if managing general partner Ken Kendrick was reluctant to invest in the team further without them showing more signs of life. Young players like Carroll, Jordan Lawlar, and Perdomo aren’t going anywhere, so it’s not hard to imagine the club being able to load up on talent this summer by moving players like Gallen and Suarez with an eye towards contending in 2026 and beyond.

Perhaps the best news for the Diamondbacks at this point is that there’s still nearly two months until the deadline, meaning they won’t need to make a decision for at least a few more weeks. A late June stretch where the club enjoys nine consecutive games against the Rockies, White Sox, and Marlins could easily provide just the sort of shot in the arm Arizona needs to get right back into the thick of the Wild Card race, especially if they’re able to take series against more middle-of-the-road clubs like Atlanta, Cincinnati, and Toronto over the next two weeks.

How do MLBTR readers think the Diamondbacks will ultimately handle their deadline dilemma? Will they push their chips in with the 2025 club, or dangle players like Gallen in hopes of building a stronger team for next year? Have your say in the poll below:

The D-backs have designated right-handed reliever Scott McGough for assignment, the team announced. His spot on the 40-man roster goes to lefty Andrew Saalfrank, who has been reinstated from the ineligible list and optioned to the Diamondbacks’ Rookie-ball affiliate in the Arizona Complex League.

Saalfrank was one of four players suspended by Major League Baseball for one year after a league investigation revealed that the quartet had placed small-scale bets on Major League Baseball games while playing in the minor leagues back in 2020-22. Saalfrank, then pitching for the D-backs’ Low-A affiliate, wagered a total of $445 over 29 bets — four of them involving Diamondbacks games.

Saalfrank is eligible for reinstatement today, as are A’s righty Michael Kelly, Padres lefty Jay Groome and Phillies infielder José Rodríguez. None of the four bet more than $749 in total, and none were on the 40-man roster at the time their bets were placed.

That’s the key distinction for that quartet receiving one-year bans as opposed to former Padres/Pirates utilityman Tucupita Marcano, who received a lifetime ban (announced in conjunction with these four suspensions). Marcano wagered more than $150K on 387 bets involving MLB games while he was on a big league roster — including 25 bets on Pirates games while he was on Pittsburgh’s major league injured list (rehabbing a season-ending ACL tear).

Major League Baseball’s rules regarding gambling stipulate that “Any player, umpire, or Club or League official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has no duty to perform, shall be declared ineligible for one year.” Players, umpires, club officials and league officials who place bets of “any sum whatsoever upon any baseball game in connection with which the bettor has a duty to perform” are subject to permanent bans. Further details on the investigation and its findings were provided in a league-issued press release last year at the time of these suspensions.

The 35-year-old McGough will lose his spot on the roster as a result of Saalfrank’s reinstatement, though he was clearly already on thin ice. Arizona originally signed McGough to a two-year contract in the 2022-23 offseason when he was coming off a strong four-year run in Japan. He logged a pedestrian 4.73 ERA in 2023 but did have some better underlying numbers, including a hearty 28.6% strikeout rate. McGough’s second year in Phoenix was a rough one (7.44 ERA in 32 2/3 innings), prompting the Snakes to decline a club option for 2025.

McGough and the D-backs eventually agreed to a minor league deal later in the offseason. He pitched well enough in an extremely hitter-friendly Triple-A setting — 13 2/3 innings, 3.95 ERA, 30 K%, 6.7 BB% — to get another big league look in mid-May, but he faltered in a quick seven-game trial run. McGough allowed five runs (6.43 ERA) and issued more walks (six) than strikeouts (five) before being optioned back to Triple-A Reno just a couple days ago. He hadn’t gotten into a game with the Aces before today’s DFA.

The D-backs will have five days to place McGough on waivers or trade him. The former seems likelier, given his struggles. Assuming he passes through waivers unclaimed, the D-backs can hold onto him as a depth piece by assigning him outright to Reno. McGough does have one prior outright in his career, so he’d be able to reject that assignment in favor of free agency if he’d prefer to again explore opportunities with other teams.
 
Diamondbacks manager Torey Lovullo has informed members of the media that right-hander Corbin Burnes will undergo Tommy John surgery. Burnes will therefore miss the remainder of this season and possibly the entire 2026 campaign as well. Radio broadcaster Chris Garagiola was among those to pass the info along. Burnes is already on the 15-day injured list but will be transferred to the 60-day as soon as the club needs a roster spot.

Corbin_Burnes_Diamondbacks-300x200.jpg


The news is devastating but unsurprising. Burnes was pitching on Sunday when he called the training staff out from the dugout. He departed that game and the club later announced that he was experiencing elbow discomfort. He went for various medical opinions in the following days but it seems the worst-case scenario could not be avoided, so he’ll go under the knife. Given that Tommy John surgery usually requires 14 to 18 months of recovery time, Burnes is definitely out for the rest of 2025. A return in late in 2026 is possible but can’t be guaranteed.

Burnes is well known as one of the best pitchers in the sport. He won a Cy Young Award while pitching with the Brewers in 2021. He posted a 2.43 earned run average in 167 innings that year. He struck out 35.6% of opponents, only gave out walks at a 5.2% clip and got grounders on 48.8% of balls in play.

His results have backed up a bit since then but he’s still been excellent. Over the next three years, his strikeout rate continued to fall but it didn’t prevent his overall run prevention much. His ERA finished around 3.00 in each season from 2022 to 2024, even though his strikeout rate fell to 30.5%, 25.5% and 23.1% in those seasons.

He was one of the top free agents in the most recent offseason. MLBTR placed him second in the class, behind only Juan Soto, predicting Burnes could land a $200MM contract over seven years. He naturally fielded a lot of interest, with clubs such as the Orioles, Blue Jays and Giants among those who were connected to him most often.

In late December, he finally picked a new team. Arizona was a surprising destination since the club already had a number of rotation options and wasn’t heavily connected to the starting pitching market. But Burnes is an Arizona native and reportedly wanted to be close to his family, so the two sides made it work. The six-year deal guarantees Burnes $210MM, though with $64MM of that deferred into the next decade. It also affords him the opportunity to opt out after the 2026 season.

The Diamondbacks had made a number of investments in their rotation in recent years but this was the largest by far. Going into 2024, they gave Eduardo Rodríguez a four-year, $80MM deal and Jordan Montgomery also got a one-year, $25MM guarantee plus an easily-attainable vesting option.

Despite the heavy amount of investment in starting pitching, the Arizona rotation hasn’t been a strength. That was true even before this Burnes news, something that MLBTR’s Anthony Franco recently took a look at in a post for Front Office subscribers.

Losing Burnes for the rest of the year will only compound the problem. Montgomery himself required Tommy John surgery before the season started, so he’s already been out of action all year. Rodríguez has a 7.05 ERA in nine starts. He went on the IL in mid-May due to shoulder inflammation and was reinstated today.

Despite having one of the best lineups in baseball, the Arizona pitching has contributed to a fairly disappointing season so far. A recent four-game win streak has got them back to .500, but their 31-31 record still has them 3.5 games out of a playoff spot at the moment. They will have to try to climb back into the race without Burnes. Their current rotation consists of Rodríguez, Zac Gallen, Merrill Kelly, Brandon Pfaadt and Ryne Nelson. Kelly is having a good year but Gallen, Pfaadt and Rodríguez are all struggling. Nelson has been in a swing role and is only now taking up a rotation spot in the wake of the injuries.

With the club hovering around contention, decisions will have to be made about the club’s deadline plans. If they fall back in the standings, they have a number of impending free agents and could have a lot to sell. That includes Gallen, Kelly, Eugenio Suárez and Josh Naylor. Montgomery is also an impending free agent but naturally has no trade value since he’s out for the year. Though if the Snakes can hang in there, adding at the deadline could obviously be the move.

Those impending free agencies and the Burnes surgery will also lead to questions about the 2026 rotation. As of now, it consists of Pfaadt, Rodríguez and Nelson. There are some prospects who could potentially take up roles but it’s clearly a very different picture to the imperfect group they have now.

Turning to the Burnes opt-out, it now seems incredibly unlikely that he triggers it. Though he could come back late next year, that will likely be for a handful of starts at most. It would be hard for him to build up enough of a platform to turn down the four years and $140MM (with deferrals) left on the deal.

That’s a largely moot point for the future. For today, the takeaway is that it’s real bad news for the Diamondbacks. Subtracting Burnes blows a big hole in their rotation right now, while the club is trying to salvage the season, and into the long-term as well.

The Diamondbacks announced a series of roster moves this afternoon, headlined by the club selecting the contract of catcher Aramis Garcia. Right-hander Cristian Mena was placed on the 15-day injured list to make room for Garcia on the active roster, while the transfer of right-hander Corbin Burnes to the 60-day IL following yesterday’s news that the veteran is set to undergo Tommy John surgery cleared a 40-man roster spot for Garcia. In addition, Arizona appointed righty Christian Montes De Oca to the roster as their 27th-man for today’s doubleheader.

Garcia, 32, was a second-round pick by the Giants back in 2014 but didn’t ultimately make his big league debut until the 2018 season. Garcia came up to the majors in August of that year to help back up Nick Hundley after Buster Posey underwent season-ending hip surgery. He got time in both behind the plate and at first base that year, slashing .286/.302/.492 across 19 games in his first cup of coffee with the big league club, though that solid 117 wRC+ came in a sample of just 65 plate appearances. Still, Garcia’s work in that first taste of the majors was enough to convince the Giants to continue rostering him for the 2019 campaign.

Unfortunately, his performance took a nose dive in that second stint as a big leaguer. He ultimately hit just .143/.217/.310 in 46 trips to the plate for the Giants that year. Despite that lackluster performance, Garcia was still in line to make the Giants’ 2020 Opening Day roster as the primary backup to Posey. That’s not how things worked out, however, as an offseason hip injury combined with the shortened 60-game campaign left Garcia sidelined for the whole year. The Giants ultimately cut the catcher loose following the 2020 season and designated him for assignment. He was claimed off waivers by the Rangers and then included in the swap that sent Khris Davis to Dallas and Elvis Andrus to Oakland prior to the 2021 campaign.

Garcia’s largest contributions in the majors came during the next two seasons. He hit .205/.239/.318 (56 wRC+) in 32 games with the A’s in 2021, but was ultimately cut from the team’s roster and signed with the Reds on a minor league deal. In Cincinnati, Garcia appeared in a career-high 47 games but hit just .213/.248/.259 with a wRC+ of 37 before getting claimed by the Orioles following the 2022 season. He bounced between the Orioles and Phillies organizations over the past two years but made just three appearances in the majors in that time before signing with Arizona on a minor league deal this past winter. Now, he’s back in the majors as a depth option behind the plate with a doubleheader scheduled today and primary catcher Gabriel Moreno day-to-day following a hand injury he suffered in yesterday’s game.

Making room for Garcia on the active roster is Mena, who is being shelved with a right shoulder strain. The right-hander has long been regarded as a talented but raw pitching prospect and was acquired from the White Sox in exchange for outfielder Dominic Fletcher prior to the 2024 season. Mena made his big league debut last year and surrendered four runs across three innings in his lone appearance, but this year he’s looked quite good with 5 2/3 scoreless innings of work and a 35% strikeout rate in a multi-inning relief role. Unfortunately, he’ll now need to wait to heal up to build on that success. For today, Mena’s spot in the bullpen will be offered to Montes De Oca, who has not yet appeared in a big league game but has a 4.07 ERA in 24 1/3 innings of work at Triple-A this year.
 
The Diamondbacks announced that they have selected the contract of left-hander Kyle Backhus from Triple-A Reno. Catcher Aramis Garcia was designated for assignment in the corresponding move on both the 26-man and 40-man rosters.

Due to a suspended game on Friday, the D’Backs and Reds played a shortened version of a doubleheader on Saturday, and Arizona used five pitchers in a 13-1 loss in the full game of the twin bill. Backhus will therefore join the roster as a fresh arm for the beleaguered D’Backs pen, and is now in line to make his Major League debut.

Though Backhus wasn’t drafted when his college career at Sam Houston State came to a close, he signed a free agent deal with the Diamondbacks in 2021 and has posted some solid numbers over five seasons in the Arizona farm system. Pitching almost exclusively out of the bullpen over the last four years, Backhus reached Triple-A for the first time in 2023, and might have reached the majors last season if injuries didn’t limit him to just 35 2/3 total innings in 2024.

Backhus has a 2.22 ERA and a 33% strikeout rate over 24 1/3 innings and 24 games in Reno this season — impressive numbers in any case, but even more noteworthy coming in the hitter-friendly Pacific Coast League. Backhus’ 9.2% walk rate is on the high side but it represents an improvement from the larger control issues that hampered Backhus earlier in his career.

This may be just a cup of coffee for Backhus in the majors, but considering how the Diamondbacks’ bullpen has struggled this year, there’s not much to lose in giving the 27-year-old more of an extended look. Jalen Beeks is the only other left-hander in Arizona’s bullpen, so Backhus can add some more balance to the relief corps while A.J. Puk continues to be sidelined on the injured list.

Garcia’s contract was selected just yesterday, as the D’Backs wanted an extra catcher available since Gabriel Moreno was nursing a hand injury suffered in Friday’s game. Moreno didn’t play Saturday but is ready to go in at least a backup capacity today, as per reporter Jody Jackson, so Garcia will now head to DFA limbo after a single game in an Arizona uniform. That lone appearance means that Garcia has now appeared in six of the last eight Major League seasons, with only four of his 120 career games coming since the end of the 2022 campaign.

Garcia has hit .211/.248/.325 over 327 plate appearances during his journeyman career, and he landed in Arizona last November on a minors contract. Garcia is out of minor league options, so the D’Backs had to designate him before trying to move him back to Triple-A, and he’ll be outrighted off the 40-man roster if and when he clears waivers. Since Garcia has been outrighted in the past, he has the right to reject another outright assignment and instead become a free agent.
 
The Diamondbacks announced that right-hander Kendall Graveman was placed on the 15-day injured list (retroactive to June 8) due to an impingement in his right hip. Righty Christian Montes De Oca was called up from Triple-A Reno to take Graveman’s spot on the active roster.

After missing all of 2024 recovering from shoulder surgery, Graveman’s 2025 debut was delayed until May 13 due to a season-opening stint on the 15-day IL due to a lumbar strain. Graveman then posted a 2.45 ERA over his first 7 1/3 innings and eight appearances for the Snakes before he struggled through a brutal outing in Saturday’s 13-1 Arizona loss to the Reds. Graveman was charged with six earned runs over just one inning of work, shooting his ERA up from 2.45 to 8.64.

It is fair to wonder if this hip problem was to blame for Graveman’s rough game, though some other red flags were there even before he took the mound on Saturday. Graveman has more walks (five) than strikeouts (three) over 8 1/3 total innings, and his 30% grounder rate is well below the 50.9% career groundball rate Graveman had posted over his nine previous big league seasons. His signature sinker is averaging 94.6mph, which is down from a 95.9mph average in 2023, though an early-season velocity drop isn’t unusual for a pitcher just coming back from a long layoff.

Unfortunately for Graveman, that nightmare against Cincinnati will represent his last game for at least a couple of weeks. This latest trip to the IL can hopefully allow the veteran to fully put his health issues behind him, and an in-form Gravement would sorely help a struggling D’Backs bullpen. Given how Arizona has a 31-34 record, Graveman (who is only signed through the 2025 season, with a mutual option for 2026) would be an obvious trade chip as a rental player if the Diamondbacks can’t get back into contention.

In other unwelcome news on the pitching injury front, righty Cristian Mena’s right shoulder strain is specifically a teres major strain, as manger Torey Lovullo told Arizona Sports’ Alex Weiner and other reporters. Mena was placed on the 15-day IL on Saturday, but Lovullo said Mena’s absence will be measured in “weeks, not days.”

The 22-year-old Mena made his MLB debut with one three-inning start with the D’Backs last season, and this year had allowed one run in 6 2/3 innings over three relief appearances. Mena was a candidate for some turns in the rotation given all of the injury problems faced by Arizona’s starters, but the righty himself has now joined the IL for what might be a lengthy period of time.
 
The Diamondbacks announced a pair of roster moves this evening, as right-hander Scott McGough elected free agency while catcher Aramis Garcia cleared waivers and was assigned outright to Triple-A. Both players had been designated for assignment by the club last week.

McGough, 35, was a fifth-round pick by the Dodgers back in 2011 but didn’t make his big league debut until 2015 when he made six ill-fated outings as a member of the Marlins. He surrendered seven runs on twelve hits and four walks while striking out four across 6 2/3 innings of work for Miami and did not appear in the majors again for quite sometime. After spending the next few years bouncing around the Marlins’, Orioles’, and Rockies’ minor league systems McGough caught on overseas with Nippon Professional Baseball’s Yakult Swallows. McGough ultimately spent four seasons in Japan and pitched quite well out of the bullpen there with a 26.0% strikeout rate and a 2.94 ERA across his 236 Central League appearances.

That work was enough to catch the attention of the Diamondbacks, who signed him to a $6.25MM guaranteed over two years ahead of the 2023 campaign. That signing did not go over well. McGough was a below average reliever by the numbers in 2023, with a 4.76 ERA (93 ERA+) in 70 1/3 innings, but some peripherals like his 25.6% strikeout rate and 3.49 SIERA suggested he had more to offer. Unfortunately, those underlying numbers collapsed in 2024 as he posted a 7.44 ERA and a 6.04 FIP across his 26 appearances while striking out just 16.7% of his opponents against a 14% walk rate. The Diamondbacks made the easy decision to decline a 2025 club option on his services last winter, though they eventually re-signed him to a minor league deal in February. When added to the roster back in April, McGough posted a 6.43 ERA in seven innings of work while walking (six) more batters than he struck out (five). He now returns to free agency in the midst of his age-35 season in search for a change of scenery as he looks to try and salvage his season.

As for Garcia, the 32-year-old was a second-rounder by the Giants in 2014 who made his big league debut during the 2018 season, when he helped fill the void when Buster Posey’s season came to an abrupt end due to hip surgery. Garcia hit .286/.302/.492 (117 wRC+) across 19 games in his first taste of major league action, but he hasn’t hit a lick since. Garcia’s appeared in the majors for five different clubs since the start of the 2019 season, and in that time he’s hit just .192/.233/.282 with a 39 wRC+. Of course, that slash line comes across a sample of just 101 plate appearances in the big leagues as Garcia has been used primarily as a third-string catcher throughout his time as a big league option. Even so, there’s been very little over the years to suggest that he’s more than a depth option behind the plate for a big league club. That’s exactly how the Diamondbacks figure to use him going forward, as his outright means he can serve as non-roster depth behind the club’s primary catching tandem of Gabriel Moreno and Jose Herrera.

The Diamondbacks announced a series of roster moves today. Right-handers Kevin Ginkel and Bryce Jarvis have been recalled from Triple-A Reno and the club has also selected the contract of right-hander Tayler Scott. To open spots for those three, righty Jeff Brigham has been optioned to Reno while righties Justin Martínez and Christian Montes De Oca have both been placed on the 15-day injured list. Martínez has a sprained right ulnar collateral ligament while Montes De Oca has right elbow inflammation. To open a 40-man spot for Scott, righty Cristian Mena has been transferred to the 60-day IL.

The news on Martínez is ominous. The righty called the training staff to the mound during last night’s appearance. It was later relayed to reporters that he was experiencing elbow tightness. A sprain, by definition, involves some stretching or tearing of the ligament. Per Nick Piecoro of the Arizona Republic, manager Torey Lovullo says Martínez is now set for a second opinion on his injury.

Whenever a pitcher’s elbow is injured, it raises alarm bells about a possible surgery and those concerns certainly appear to be warranted here. It should be pointed out that not all sprains necessarily lead to a operation. To pick one recent example, Mason Miller was diagnosed with a mild UCL sprain in May of 2023 and ultimately did not head to the surgeon’s table. However, it took him four months to get back on the mound, as he wasn’t reinstated from the IL until September of that year.

It may take a few more days to determine the prognosis with Martínez but it seems like it will be an unfortunate development regardless. The righty seemed to break out as one of the best relievers in the sport last year. He tossed 72 2/3 innings for the Diamondbacks with a 2.48 earned run average. His 11.7% walk rate was certainly high but he struck out 29.5% of opponents and got grounders on 58.9% of balls in play.

The Diamondbacks believed in that breakout enough to lock up Martínez for the long term. He and the club agreed to a five-year extension in March that guarantees him $18MM, with two club options as well. Unfortunately, the first season of that deal has been a bit of a bust so far. Martínez already missed about three weeks due to some shoulder inflammation and is now back on the IL again with an even scarier diagnosis. He has only been able to throw 15 1/3 innings with a 4.11 ERA this year.

Martínez and A.J. Puk were supposed to be the two big weapons in the Arizona bullpen this year. Puk made just eight appearances before landing on the IL in mid-April due to elbow inflammation. He was later diagnosed with a flexor strain and transferred to the 60-day IL. His return timeline is unclear. Now it seems possible the Snakes may have to proceed without either of those hurlers for a while. They also put Kendall Graveman on the 15-day IL yesterday due to a hip impingement.

It’s the latest punch in what has been a bruising season for the Diamondbacks. They have lost starters Corbin Burnes and Jordan Montgomery to Tommy John surgery. Their bullpen has taken a number of hits. Some of their healthy pitchers have been underperforming. Though the Snakes came into the season with high hopes, they are now fourth in the National League West and 5.5 games back in the Wild Card race, a less than ideal time to be hemorrhaging key players.

If Martínez does have a serious injury, there would be one silver lining for the Diamondbacks in the long term. His extension has a conditional club option for 2032, valued at just $3MM. That would be triggered if he requires surgery or missed a certain number of days on the IL during the course of the deal.

While the club awaits for information there, they have to proceed with the business of the games on the schedule. They have added a number of arms to the active roster, which includes adding Scott to the 40-man. The 33-year-old Scott elected free agency last month after being designated for assignment by the Astros, which led to a minor league deal with the Diamondbacks.

He seemed to have a nice late-bloomer breakout with Houston last year, posting a 2.23 ERA over 68 2/3 innings. He struck out 25.2% of batters faced, though also gave out walks at a 12.4% pace. There was likely a bit of luck in that ERA, as his .230 batting average on balls in play and 84.9% strand rate were both to the fortunate side. ERA estimators like his 4.13 FIP and 4.04 SIERA pointed to some regression though still suggested he could be a capable big league arm.

The pendulum swing ended up being quite strong. He posted a 5.40 ERA through 16 2/3 innings to start this year. His .313 BABIP and 65.2% strand rate went to the other side of average as his strikeout rate fell to 20.5% and his walk rate climbed to 15.4%.

Since he’s out of options, that got him bumped off the roster and to free agency. Since landing with the D’Backs, he has thrown 3 1/3 scoreless innings for Reno. He may have a tenuous grasp on a roster spot, given his out-of-options status, but he, Ginkel and Jarvis will give the club three fresh arms after they used eight different pitchers to get through yesterday’s 11-inning game against the Mariners.

As for Mena, he just landed on the IL a few days ago with a shoulder strain. Lovullo said his absence would be measured in “weeks, not days.” Given today’s IL transfer, he will be ineligible for reinstatement until early August.

The Diamondbacks released lefty Joe Mantiply after his recent DFA, per their transaction log at MLB.com. Assuming he clears release waivers, he’ll be a free agent who can sign with any team tomorrow afternoon.

Mantiply, 34, has been a frequent presence in Arizona’s bullpen dating back to 2021. From ’21-’24, he pitched 198 1/3 innings with a 3.63 ERA, a 22% strikeout rate, a 6.1% walk rate, a 51.9% grounder rate, 50 holds and three saves. In 2022, specifically, he was one of the team’s most frequently used relievers in high-leverage spots.

The 2025 season has been an abject disaster for Mantiply, however. He fired a perfect inning in his first appearance of the season and immediately tanked thereafter. By the time Arizona optioned Mantiply to Triple-A Reno on April 19, he’d been tagged for a calamitous 13 runs in just 7 1/3 innings across eight relief outings. He got another look in mid-May and was quickly optioned again after surrendering four runs in 2 1/3 innings.

Even Mantiply’s time in Triple-A was generally a struggle. He allowed four runs in his first appearance with Reno and five in his final one. Those ugly outings bookended a strong run of 9 2/3 shutout innings, but the overall results were grim. In 9 2/3 MLB frames this year, Mantiply has a 15.83 ERA. He’s posted a 5.56 mark in 11 1/3 Triple-A innings.

Mantiply has always been a soft-tosser, but his fastball has bottomed out in 2025, averaging a career-low 88.2 mph. He sat 91.3 mph with the pitch back in 2021-22, when he was at his best, and was at 89.5 mph last year. He’s still filling up the strike zone, but doing so with diminished stuff has yielded diminished returns.

By all accounts, Mantiply is healthy at the moment. Teams are always in need of left-handed bullpen help, and Mantiply has a generally solid track record in the majors, so he ought to get another chance to turn his season around with a new club before too long. He’ll almost certainly need to pitch his way back to the majors on a minor league deal, however. He’s being paid $1.7MM this year, and the D-backs will remain on the hook for the rest of that salary — minus the prorated minimum for any team he spends with another club’s big league roster.
 
Diamondbacks right-hander Justin Martínez will undergo Tommy John surgery. Arizona manager Torey Lovullo relayed the info today, per John Gambadoro of Arizona Sports 98.7 FM Phoenix. He’ll miss the remainder of this season and a decent chunk of 2026 as well. He is already on the 15-day injured list but will be transferred to the 60-day IL once the club needs to open a roster spot.

The news is devastating but not especially surprising. Earlier this week, Martínez landed on the IL and the Diamondbacks announced his injury as a sprain of his right ulnar collateral ligament. A sprain, by definition, involves some degree of stretching or tearing. Not all UCL sprains lead to surgery but many do.

Now that Martínez will go under the knife, he’ll be out of action for a long time. The surgery usually takes 14 to 18 months of recovery, so he’ll certainly out for the rest of this season. A return in the second half of 2026 is possible but not a guarantee.

That’s a huge blow for the Arizona bullpen. Martínez broke out last year with 72 2/3 innings with a 2.48 earned run average. His 11.7% walk rate was a bit high but he punched out 29.5% of batters faced and got opponents to pound 58.9% of balls in play into the ground.

Coming into 2025, he and A.J. Puk were supposed to be the anchors of the bullpen. The Snakes even gave Martínez a five-year, $18MM extension to cement him as part of the long-term plans. But Martínez has been on and off the IL this year, first due to shoulder inflammation and now this UCL injury. Puk has also been on the IL for almost two months now due to elbow inflammation.

Naturally, missing those two has hampered the bullpen. Arizona relievers have a collective 5.21 ERA this year, which is better than just the Angels, Nationals and Athletics. The club is 34-34 on the year, 4.5 games back of a playoff spot. Puk could be back at some point later in the year but they will have to try to survive without Martínez. If they hang in the race long enough to be buyers, then adding bullpen help at the deadline would make plenty of sense.

For the team, there is one silver lining. The extension they signed with Martínez contained two club options for 2030 and 2031, followed by a conditional club option for 2032. That conditional option would be worth $3MM and would be unlocked if Martínez required elbow surgery or spent a certain number of days on the injured list during the course of the deal. Now that he is going under the knife, that option will be officially available to them.

That’s assuming Martínez can get back on the mound and return to his previous form, which would prompt the Snakes to pick up those club options. Though Tommy John surgeries are quite common, not all pitchers can get 100% effectiveness back afterwards. Martínez is also undergoing the procedure for a second time, which adds to the risk. He first went under the knife as a prospect in 2021.

Diamondbacks reliever A.J. Puk has paused his throwing program after experiencing renewed elbow soreness, manager Torey Lovullo told reporters on Friday (link via Nick Piecoro of The Arizona Republic). Puk will visit Dr. Neal ElAttrache before deciding on next steps. Lovullo called it “slight discomfort” and noted that the star southpaw initially hoped he could continue throwing through it.

Puk has been out since the middle of April with a flexor strain. The organization has remained hopeful that he’ll be able to rehab the injury without requiring surgery. That’s presumably still the case, but any kind of setback for a forearm/elbow injury is worrisome. That’s especially true considering Puk has a 2018 Tommy John surgery on his medical chart. Even if the follow-up visit goes well, the shutdown will push back his return timeline to some extent.

It’s the latest bad news for a reeling Arizona bullpen. Puk and Justin Martinez were supposed to serve as Lovullo’s 1-2 punch in the late innings. Puk made eight appearances before his IL stay. Martinez got into 17 games and suffered an elbow injury of his own last week. That one immediately proved serious, and the team announced this evening that he’s headed for the second elbow surgery of his career.

Arizona’s bullpen has been a huge weakness. They entered play tonight with a 5.21 earned run average that ranks 27th in MLB. The injuries to Puk and Martinez are the biggest factors, but they’ve also seen former key contributors Ryan Thompson and Kevin Ginkel struggle through rough years. Low-cost acquisitions Shelby Miller and Jalen Beeks have been their most reliable relievers. The D-Backs will need to acquire multiple bullpen arms if they’re in position to add at the deadline.
 
The Diamondbacks signed reliever Matt Foster to a minor league contract. The move was announced by their Triple-A club in Reno.

Foster, 30, had been pitching for the Algodoneros del Unión Laguna in Mexico for the past month and a half. He thrived in that extremely hitter-friendly setting, allowing only two runs (one earned) through 13 2/3 innings. The righty punched out 13 and didn’t walk any of the 51 batters he faced. It didn’t take long with that kind of production for the Alabama product to find his way back to affiliated ball.

The D-Backs are only the second MLB organization of Foster’s career. He was drafted by the White Sox in 2016 and pitched parts of four seasons for Chicago. Foster’s best season came in 2020, when he turned in a 2.20 ERA while striking out 28% of opponents across 28 2/3 innings. His production tailed off between 2021-22 and he underwent Tommy John surgery early in 2023. Foster missed the entire season and only managed 6 2/3 big league frames late last year. Those came with a 91.9 MPH average fastball velocity that was down two ticks from where he’d been sitting before the surgery.

Arizona’s bullpen has been decimated by injury. Justin Martinez, Cristian Mena, A.J. Puk, Kendall Graveman and Christian Montes De Oca are all on the shelf. Martinez and Montes De Oca have undergone surgeries, and Mena is out for multiple months. Puk was recently shut back down from throwing and is headed for further evaluation due to lingering soreness as he rehabs a flexor strain.
 
Just one day after Diamondbacks closer Justin Martinez underwent Tommy John surgery, fans in Arizona received more troubling news about the status of the bullpen when manager Torey Lovullo told reporters (including Alex Weiner of AZ Sports) that right-hander Christian Montes De Oca is set to undergo lower back surgery that could keep him out of commission for the remainder of the 2025 season. Montes De Oca was placed on the injured list earlier this week due to inflammation in his right elbow, but is now ticketed for an unrelated procedure on top of that issue.

It’s a brutal turn of events for the 25-year-old, who made his big league debut just last week and has one scoreless outing of long relief under his belt in the majors at this point. The right-hander looked great in that debut, with zero hits and one walk allowed as he struck out two in 2 2/3 innings of work. It appears that may be his only appearance in his debut season unless he’s able to both overcome the elbow inflammation he’s been battling and his upcoming back surgery in time to get back on the mound for the Diamondbacks before the end of the year. If there’s a silver lining in the announcement, it’s that Montes De Oca will be able to try and address both issues at once rather than dealing with multiple prolonged layoffs.

Montes De Oca signed with Arizona out of the Dominican Republic and made his pro debut during his age-22 season back in 2022. A pure relief prospect from the jump who has never started a game as a pro, Montes De Oca nonetheless moved through the Arizona system quite quickly. He began his second pro season at the Double-A level and spent barely any time at Double-A in his third pro season before making the jump to Triple-A. He struggled in that first taste of the Pacific Coast League last year, but in 2025 he managed a solid 4.07 ERA and 3.66 FIP with a 25.5% strikeout rate and a walk rate of just 5.9%.

Montes De Oca joins Martinez, A.J. Puk, Corbin Burnes, Jordan Montgomery, Blake Walston, and Cristian Mena on a rapidly growing list of Diamondbacks pitchers facing extended absences. Impressive rotation depth has allowed them to weather the storm in terms of starting pitching, but the club’s relief depth has been whittled down to the point where closer Shelby Miller and lefty Jalen Beeks are the only two reliable leverage arms at Lovullo’s disposal until another option emerges internally, an external addition is made, or Puk returns from his own bout of elbow inflammation. Pitching woes are a major piece of what’s left Arizona 3.5 games out of a Wild Card spot, although the club remains one game over .500 and could theoretically look to shore up its pitching depth this summer if the team’s internal options can keep them in the race until trade season begins in earnest.
 
The Diamondbacks have agreed to a deal with lefty reliever Anthony Gose, reports Jon Heyman of the New York Post. Gose has spent the season thus far with the Mets organization, but the MiLB transaction log reflects that he was quietly released yesterday. Whether that was an opt-out clause, an upward mobility clause or a straight release remains to be seen, but Gose is headed to a new organization. If it’s a big league deal, the Diamondbacks will need to make a corresponding move, as their 40-man roster is currently at capacity. The team has not yet formally announced the signing.

Gose, 34, began his career as an outfielder back in 2008, when the Phillies selected him in the second round of the draft. He quickly became one of the game’s top prospects and wound up seeing action in parts of five major league seasons as an outfielder — all between the Blue Jays and Tigers. Gose’s career looked to have stalled out, but the former two-way star in high school reinvented himself as a relief pitcher back in 2017-19 and has now pitched in parts of three MLB seasons — all with Cleveland.

Gose made his major league debut as a full-time pitcher in 2021 and has now pitched 32 MLB frames with a 4.78 ERA, a 29.7% strikeout rate and a 12.3% walk rate. Injuries, most notably Tommy John surgery, have limited his time on the mound and impacted him when healthy. He’s also missed time with a triceps strain, a calf strain and shoulder soreness since moving to the mound.

Between those injuries and the fact that he’s now approaching his 35th birthday, perhaps it shouldn’t be all that surprising that Gose’s heater has lost some life. When he first moved to the mound, he was brandishing a blazing four-seamer that averaged better than 99 mph and reached triple digits at times. He sat 95.7 mph in both Triple-A and the big leagues last year, and he’s dipped further to an average of 94.6 mph in 2025.

Gose has pitched 23 innings with the Mets’ affiliate in Syracuse and logged a 4.30 ERA, 24.5% strikeout rate, 13.7% walk rate and 30.6% ground-ball rate. He started the season pitching quite well, yielding a 3.31 ERA through his first 16 1/3 innings, but he’s been hit hard over the past few weeks; dating back to May 17, Gose pitched in six games and was rocked for seven runs (five earned) on nine hits and three walks with seven strikeouts.

The D-backs are starved for arms, having recently lost Justin Martinez to Tommy John surgery, Christian Montes De Oca to back surgery and Kendall Graveman to a hip injury. Lefty A.J. Puk has been out since early April due to elbow troubles. Over in the rotation, Corbin Burnes recently suffered a UCL tear that necessitated Tommy John surgery as well. The D-backs have added righties Anthony DeSclafani and Tayler Scott in recent weeks, and Gose will now add another left-handed option to the depth chart.
 
The Diamondbacks have signed right-hander Trevor Richards to a minor league deal, according to his transactions tracker at MLB.com. He has been assigned to Triple-A Reno alongside lefty Anthony Gose, per the southpaw’s tracker. It was reported earlier this week that the Snakes would be signing Gose but it wasn’t clear if it was a major or minor league deal.

Richards, 32, has had some major league success but has been in poor form for about a year now. The Blue Jays dealt him to the Twins at last year’s deadline but Richards lasted only 13 innings with Minnesota before being outrighted off the roster. In that time, he walked 11 opponents, a rate of 18.6% of batters faced. He also hit two other batters and issued seven wild pitches.

Here in 2025, he has signed minor league deals with the Cubs and Royals, getting a brief look in the majors with the latter club. He has thrown 19 1/3 minor league innings this year with a 4.19 earned run average, 25.6% strikeout rate and 13.6% walk rate. In his quick major league stint with Kansas City, he allowed four earned runs in three innings.

Prior to those struggles, he had a good run in the big leagues. He tossed 201 innings over the 2021-23 seasons with a 4.61 ERA, 31.3% strikeout rate and 10.9% walk rate. He earned one save and 25 holds in that time.

The Arizona bullpen has taken a few punches this season. The relief group was supposed to be anchored by A.J. Puk and Justin Martínez but both are currently out of commission. Martínez recently required Tommy John surgery and will be out for the year. Puk is on the IL with a flexor strain and was recently shut down due to some renewed discomfort. In addition to those two, Kendall Graveman and Christian Montes De Oca are also on the IL.

Amid those injuries, the club’s bullpen numbers are unsurprisingly poor. Arizona relievers have a collective 5.39 ERA, which puts them ahead of only the Nationals and Athletics. If they stay in the playoff race, adding relievers will surely be a deadline focus. For now, they’ll take chances on guys like Richards and Gose while hoping for the best.

The Diamondbacks announced Thursday that they’ve placed catcher Gabriel Moreno on the 10-day injured list due to a right hand contusion (retroactive to June 16) and selected the contract of fellow catcher Aramis Garcia from Triple-A Reno. Righty Christian Montes De Oca was transferred from the 15-day IL to the 60-day IL to open a 40-man spot for Garcia, who returns just nine days after being outrighted off the 40-man roster.

Moreno originally hurt his hand while trying to block a wild pitch earlier this month. He’s played just three games in 12 days since taking that errant pitch off his hand. Arizona was clearly hoping to avoid an IL stint, but things have reached a point where they’ll sit him down for the next week and get another catching option on the roster to complement Jose Herrera.

The 25-year-old Moreno is enjoying another solid all-around year. The former top prospect’s .270/.324/.414 batting line isn’t elite but is firmly above league average (106 wRC+). That’s big production from any catcher, a position that is regularly manned by below-average hitters, but it’s especially nice for a player with Moreno’s elite defensive grades. He draws plus marks for his framing, blocking and throwing alike. Since 2023, he ranks as the game’s third-best defender behind the plate, by measure of the Defensive Runs Saved metric, and the seventh-best in MLB according to Statcast. Because Moreno’s IL stint is backdated three days (the maximum allowed under MLB rules), he’ll be eligible to return a week from now.

As for Garcia, he’s a 32-year-old journeyman who was briefly up with the Snakes in the wake of the original injury to Moreno. He only appeared in one game, however, and didn’t take a plate appearance before being designated for assignment and passed through waivers. He’s played in parts of six big league seasons and carries a career .211/.248/.325 line in 327 trips to the plate during that time. He currently sports a .250/.399/.524 line in 38 Triple-A games and is a career .235/.306/.430 hitter in parts of seven seasons at that level.

Presumably, Garcia will see a bit more game action this time around. Herrera, who’ll serve as the primary catcher with Moreno down, has played eight games in 12 days since Moreno was originally banged up. It’s a heavy workload for any catcher but particularly a glove-first backup who’s hitting .171/.284/.244. Herrera is up to 101 plate appearances this year — already just 23 shy of his career-high in the majors, where he’s a lifetime .199/.279/.256 hitter.

The 60-day IL move for Montes De Oca was an inevitability. The 25-year-old righty landed on the injured list earlier this month due to elbow inflammation, but the D-backs announced five days ago that he was headed for surgery to repair a stress fracture in his lower back. That surgery was likely to take him out for most or all of the remaining season anyhow — a miserable turn of events for a young hurler who’d tossed 2 2/3 innings of scoreless ball in his MLB debut just days prior to landing on the injured list.
 
Diamondbacks reliever A.J. Puk underwent elbow surgery today, manager Torey Lovullo tells the Burns & Gambo show. Puk had visited Dr. Neal ElAttrache after experiencing recurring soreness as he tried to work back from a flexor strain. Lovullo didn’t have specific details as to whether he required a full Tommy John ligament replacement or some kind of modified internal brace procedure. Puk’s season is over in either case. He’s likely to miss most or all of 2026 as well.

Additionally, the manager told Burns & Gambo that catcher Gabriel Moreno has a hairline fracture in his right index finger. The D-Backs placed Moreno on the 10-day injured list yesterday but had initially called it a hand contusion. He has evidently been playing through an undiagnosed fracture for some time. A return timetable is unclear but will be measured in “weeks, not days.” Topping it all off, Nick Piecoro of The Arizona Republic reports that left-hander Tommy Henry is also headed for season-ending elbow surgery.

The news on Puk is terrible but unsurprising. He has been plagued by elbow issues for the past two months. He’d undergone Tommy John surgery once before in his career. The 6’7″ southpaw required the procedure in 2018 when he was a member of the A’s farm system. He missed that season and was limited to 28 combined appearances between the minors and MLB the following year.

Acquired from the Marlins at the 2024 deadline, Puk has been one of the most dominant relievers in the sport since getting to Arizona. He recorded 43 strikeouts in 27 1/3 innings after the trade last summer, working to a 1.32 ERA in the process. He had fanned 12 more hitters against two walks while collecting four saves in his first eight appearances this year. Aside from a terrible stint in Miami’s rotation early last season, he has been generally excellent since the A’s traded him to Miami over the 2022-23 offseason.

Depending on the nature of the surgery, there’s a decent chance this will end his time with the D-Backs. Puk has over five years of MLB service. He’ll be eligible for arbitration for the final time next offseason. He’d earn only a modest raise on this year’s $2.95MM salary, but a full ligament repair would make him a non-tender candidate. Players usually require 14-plus months to return from Tommy John surgery, and that would be Puk’s second such procedure. He’s likely to be out through next year’s All-Star Break even if he “only” needed the internal brace procedure, though the D-Backs would happily retain Puk for around $3MM if they felt they could get half the season from him.

The news on Puk comes a week after Justin Martinez, the team’s other top reliever, also went under the knife. Corbin Burnes and Jordan Montgomery have been Tommy John victims in the rotation. It’s difficult for any team to weather that kind of injury luck. Arizona has hovered around .500 despite having an elite offense because of their issues on the mound.

They’ll lose Moreno from that lineup for what seems like a decent chunk of time. There’s a significant drop off to light-hitting backup Jose Herrera. The Snakes selected Aramis Garcia to work off the bench behind Herrera. Adrian Del Castillo is the only other catcher on the 40-man roster. He’s a far better hitter than either Herrera or Garcia but isn’t regarded as a great defender. Del Castillo won’t be an option in the immediate future regardless, as he landed on the Triple-A injured list today with what is expected to be a minor back injury. Moreno will be the clear starting catcher once he’s healthy, but his injury could lead the Snakes to pursue a veteran #2 who can provide more punch than Herrera offers.

Henry, 27, is a former second-round pick who has a 5.07 ERA over 37 career appearances. He has an ERA above 8.00 over 11 starts in Triple-A Reno this year. This is his final minor league option season and he seems unlikely to stick on the 40-man roster throughout the offseason. His elbow injury occurred in Triple-A, so he’s on the minor league injured list. He’ll continue to count against the 40-man for now. The D-Backs may place him on the MLB 60-day IL or simply decide to release him (which would save them a bit of money relative to putting him on the MLB injured list) once they need another roster spot.
