I don't think any of the members here (active ones, at least) have a job in sports. I always thought being a ball boy/bat boy for an MLB team would be awesome, though.
I used to write for auto racing for a few years. Wrote for the local track's book a few times, then got hired to write for a website.
Unfortunately, I was let go before the 2011 season because of my style. That was fine - life started to go downhill from there, and my mind used to be elsewhere.
I don't have an official, paid job in sports. However, one thing I do have is volunteer hours in jobs at sports events like organizing races and such. I need to start collecting volunteer hours for highschool so now is certainly a great time to start collecting them by helping with something that I enjoy.
