Red Sox Designate Luis Guerrero For Assignment

The Red Sox announced that right-hander Luis Guerrero has been designated for assignment. The Sox had several players who needed to be reinstated from the 60-day injured list and needed to open a 40-man spot.

Many teams in the league face roster crunches at this time of year. The 60-day IL goes away five days after the World Series and doesn’t come back until spring training. When players are reinstated from the 60-day IL, they need to retake spots on the 40-man roster. Some players will reach free agency, which opens some space, but teams often end up needing to open spots. This move gets the Sox to 40 for now, but they will probably want to open more spots later. They will likely want to add players ahead of this month’s Rule 5 deadline, in addition to signing free agents throughout the winter.

Guerrero, 25, was a 17th-round pick in the 2021 draft. Exclusively a reliever, he worked his way up the minor league ladder. He was added to the club’s 40-man roster in September of last year. He has mostly been kept in the minors.

Between last year and this year, he has thrown 27 1/3 big league innings with a 2.63 earned run average. His 44.4% ground ball rate is decent but his 17.6% strikeout rate and 14.8% walk rate are poor figures. His ERA is being held down by a tiny .205 batting average on balls in play. His 3.51 FIP and 5.28 SIERA suggest he’s been quite fortunate in this small sample. His fastball averages in the upper 90s while he also throws a slider and a changeup.

In the minors, he has occasionally shown good strikeout stuff but also with poor control. From 2022 to 2024, he tossed 147 2/3 innings on the farm with a 2.93 ERA. He walked 13.4% of batters faced but also punched them out at a 32.1% clip. In 2025, his minor league results backed up. He tossed 26 2/3 Triple-A innings with a 4.39 ERA, 19.8% strikeout rate and 14.7% walk rate.

He was placed on the major league injured list in late June due to a right elbow sprain. He was transferred to the 60-day IL. He finished the season there, though he did pitch in the minors on a rehab assignment before the season was done.

Presumably, his tough year contributed to him getting nudged off the roster. The Sox will now have a week to trade him or pass him through waivers. The waiver process takes 48 hours, so any trade talks will have to take place in the next five days. Guerrero is coming off a tough year but still has options and has shown flashes of potential in the minors.

Red Sox, Cooper Criswell Agree To Deal For 2026

The Red Sox and righty Cooper Criswell have agreed to terms on a contract for the 2026 season, reports FanSided’s Robert Murray. Criswell, a client of Republik Sports, was already on the 40-man roster but wasn’t necessarily a lock to stick all offseason. He’s now agreed to a fully guaranteed $800K, per Murray, which greatly enhances his chances of staying in place.

Boston could still pass Criswell through waivers at some point this winter. He’s out of minor league options and would thus need to break camp with the club or else be designated for assignment. The fully guaranteed $800K, while only a bit north of the league minimum salary, makes it less likely that he’d be claimed by another club and also ensures that Criswell would accept an outright to the minors. He’d have the right to reject a minor league assignment upon clearing waivers by virtue of the fact that he’s been outrighted in the past, but he doesn’t have the service time necessary to reject and retain the remainder of that guarantee.

The 29-year-old Criswell appeared in seven games for the Sox this year, logging 17 2/3 innings of 3.57 ERA ball but with only an 11.3% strikeout rate. He’s totaled 154 2/3 innings across parts of five major league seasons and carries a career 4.48 ERA, 16.7% strikeout rate and 7.1% walk rate between the Angels, Rays and Red Sox. He also tossed 65 2/3 innings of 3.70 ERA ball for the Sox’ Triple-A affiliate in Worcester this season, working primarily as a starter.

While Criswell isn’t going to be penciled into next year’s rotation, he’ll be a depth option and could compete for a swing role in camp. Rotation help will be a focus for Red Sox chief baseball officer Craig Breslow this winter. Ace Garrett Crochet will again lead the rotation. He’ll be followed by Brayan Bello, but the rest of the group is more in flux. Kutter Crawford missed the entire season due to oblique and wrist injuries — the latter requiring surgery in July. Tanner Houck had Tommy John surgery this summer. Hunter Dobbins’ season ended with an ACL tear. Lucas Giolito is a free agent.

Top prospects Payton Tolle and Connelly Early debuted late in the season and impressed to varying extents, but neither will simply be handed a rotation spot. Veteran Patrick Sandoval should be healthy after spending 2025 rehabbing from UCL surgery. Former top prospect Kyle Harrison, acquired in the Rafael Devers trade, will be in the mix — as will righty Richard Fitts. There are plenty of in-house options, but some of those names could move to the bullpen and others may need more time in Triple-A. Adding a playoff-caliber arm to the rotation mix seems likely, whether that addition comes via free agency or trade.

Lucas Giolito Wants To Return To Red Sox, Says He’s “Fully Healthy” After Late-Season “Freak Injury”

After UCL surgery cost him the entire 2024 season, Lucas Giolito returned in 2025 to post solid results (3.41 ERA in 145 innings) in the Red Sox rotation before the injury bug arose just prior to the start of Boston’s Wild Card Series with the Yankees. Right flexor irritation and a bone issue kept Giolito off the playoff roster and unable to do anything besides watch as the Sox were eliminated in three games.

Adding to Giolito’s frustration was the fact that after getting the diagnosis and beginning some rehab work, “within three days, my elbow felt 100 percent fine again,” the right-hander told WEEI.com’s Rob Bradford on the latest edition of the Baseball Isn’t Boring podcast (partial transcript here). With no UCL damage discovered and the inflammation subsided, Giolito planned to quickly start a throwing program with the intention of returning later in the playoffs, except Boston’s run was cut short early.

As the offseason and Giolito’s free agency now begins, he said that is now “fully healthy,” even though he understands the complications that bought on by his late flexor issue. He said he is “happy to prove that I’m fully healthy in any way possible” to any skeptical front offices, and that the injury is completely behind him.

There’s no injury, or whatever injury there was is gone. It was a weird, freak thing that popped up at the worst possible time, not only for the Red Sox but for myself and in general,” Giolito said. “Just the worst possible time. It makes my free agency harder. It prevented me from pitching in the playoffs where I had been a part of the rotation pretty much the entire year. It was just a very, very tough one to swallow. I still don’t like thinking about it.”

Giolito signed a two-year, $38.5MM deal with the Red Sox during the 2023-24 offseason that broke down as an $18MM salary for 2024 and then a player option for a $19MM salary in 2025. Giolito’s internal brace procedure made it an easy call for him to exercise that $19MM option and remain in his Sox contract, and remaining in the deal also added a club option for 2026 worth at least $14MM. Since Giolito then tossed at least 140 innings in 2025, the club option was converted to a $19MM mutual option with a $1.5MM buyout, giving Giolito the right to test free agency again if he declined his end of the mutual option.

That is exactly what happened earlier this week, and Giolito finds himself on the open market again. He doesn’t have the qualifying offer attached to his services since the Sox didn’t issue him the one-year, $22.025MM offer. Giolito told Bradford that he didn’t expect the QO due to his injury: “You end of the year hurt, it puts a bad taste in the team’s mouth. It is what it is. Now, the fortunate side is that it was like the most benign, weird, freak injury that went away after a few days. So, now I’m like, great. I’m having a fully healthy, amazing offseason.”

Sour ending notwithstanding, Giolito still viewed his 2025 campaign as “really, really positive” given his own success and Boston’s success in returning to the playoffs. He is also hoping for an encore performance at Fenway Park in 2026 and beyond.

I made it clear to everybody. I would love to come back here and continue to play for the Red Sox. It’s the most fun I have ever had having a season with a team in the big leagues,” Giolito said. “I felt like the way it ended left such a bad taste in my mouth, and the rest of the team, particularly me not being able to pitch in that playoff series. It really sucked. I was like I really hope I can come back, and it goes better for us next time.”

MLBTR ranked Giolito 27th on our list of the offseason’s top 50 free agents, and projected the right-hander to land a two-year, $32MM contract. There was a bit of flexibility within that projection since some teams may feel comfortable enough in Giolito’s health to add a club/vesting option for a third year, or perhaps even just a fully guaranteed third year.

This mid-range price tag should put Giolito on the radar for a lot of clubs, and a return to Boston certainly seems plausible since the Sox are still in need of pitching. The expectation is that the Red Sox will pursue a frontline arm to team with Garrett Crochet atop the rotation, but adding this hypothetical ace and Giolito would only deepen the rotation and make the Sox better equipped for a longer postseason run.

Nick Kurtz Wins American League Rookie Of The Year, Earns Full Year Of Service Time

Athletics first baseman Nick Kurtz has been named the 2025 American League Rookie of the Year, the Baseball Writers Association of America announced. His teammate Jacob Wilson finished second and Roman Anthony of the Red Sox finished third in the voting. Kurtz, who was the unanimous choice for the award, will be retroactively awarded a full year of service time by finishing in the top two of the voting. The full voting results can be found here.

NickKurtz-2025-300x200.jpg


Kurtz was the fourth overall pick of the 2024 draft and came into 2025 as one of the top prospects in the league. He didn’t break camp with the club but was called up on April 23rd. Almost immediately, he started showing his talent for crushing the ball. Due to his late call-up and a brief injured list stint for a strained left hip flexor, he only got into 117 games, but that was still enough time for him to put the ball over the fence 36 times.

It wasn’t a perfect season, as Kurtz struck out at a high 30.9% rate. However, his 12.9% walk rate was quite strong. When combined with his aforementioned power, it was a very productive season. His .290/.383/.619 slash line translated to a wRC+ of 170. Among hitters with at least 20 plate appearances this year, only Aaron Judge and Shohei Ohtani topped that wRC+ number.

It’s impressive that Kurtz did so much despite not even playing a full season. His late call-up also has notable implications for him and the club. The most recent collective bargaining agreement included measures to discourage service time manipulation. If a team promotes a top prospect early enough in a season for him to earn a full service year, the team can earn an extra draft pick if the player meets certain awards voting criteria, via the Prospect Promotion Incentive. On the flip side, if a player is not promoted early enough for a full service year and then goes on to finish in the top two of Rookie of the Year voting in his league, then he is retroactively credited with a full service year.

Kurtz came into the year as a consensus top 100 prospect in baseball, meaning he would have been PPI-eligible this year if the A’s had called him up earlier. He only got 159 days of service, 13 shy of the 172 needed for a full season. If he were PPI-eligible, this award win would have netted them an extra draft pick in 2026. Since they did not call him up early enough and Kurtz finished in the top two of the voting, he will get a full year of service anyway. That reduces the club’s window of control over Kurtz from six years to five, meaning he’s now on pace to reach free agency after 2030 instead of 2031.

Wilson is Kurtz’s teammate but the two are polar opposites when it comes to their offensive profiles. While Kurtz strikes out a lot but also draws walks and has huge power, Wilson has modest power and rarely walks but almost never strikes out. His 7.5% strikeout rate this year was the second-lowest among qualified hitters, trailing only Luis Arráez. Wilson only hit 13 home runs and drew a walk in just 5.2% of his plate appearances, but he still managed to hit .311/.355/.444 for a 121 wRC+ while playing the premium position of shortstop, even if his defense wasn’t highly rated.

The shortstop actually got promoted in July of 2024 but he landed on the injured list and missed enough time to still have rookie status coming into 2025. Despite having rookie status, he would not have earned the A’s a PPI pick even if he had finished first in the voting. Players are ineligible for the PPI bonus if they have at least 60 days of service time. Wilson earned 73 days of service in 2024, much of it on the injured list, meaning he was in a weird twilight zone of being rookie eligible but not PPI eligible.

Anthony came into the year not only as a top 100 prospect but most rankings had him first or second in the league. However, the Red Sox had a crowded outfield mix that was difficult for him to break into. Eventually, injuries opened a path and he finally got the call in June. By August, he had impressed the Sox enough that they signed him to an eight-year, $130MM extension.

Though he only got into 71 games, Anthony slashed .292/.396/.463 for a 140 wRC+ and stole four bases. He was credited with seven Defensive Runs Saved and six Outs Above Average. FanGraphs credited him with 2.7 wins above replacement in less than half a season. He would have pushed those numbers even further if not for an oblique injury sending him to the IL in early September.

Anthony only got 112 service days this year. He would have earned a full year if he had cracked second place in the voting, though that is largely a moot point with his extension. However, the result does impact him financially when looking at the details of his pact. The deal contains a number of escalators which Anthony can unlock via awards voting. Some extra money could have been tacked on with a top two finish but this third-place finish isn’t enough for him to add anything to the $130MM total. He can still push that up in the future by getting MVP votes.

Several other players received some recognition from the voters. Noah Cameron of the Royals finished fourth in the voting, followed by Colson Montgomery of the White Sox, Carlos Narváez of the Red Sox, Jack Leiter of the Rangers, Will Warren of the Yankees, Luke Keaschall of the Twins, Braydon Fisher of the Blue Jays, Shane Smith of the White Sox, Cam Smith of the Astros, Chandler Simpson of the Rays, Luis Morales of the A’s and Jasson Domínguez of the Yankees.
