I got really frustrated with this one, since I was sure that it was someone I knew. I thought I could picture him. So I went and looked it up. I had a few guys in mind, but it turns out I never really heard of this guy before. (At least, the name didn't really ring any bells.)
Before I let fly with my ill-begotten knowledge (researching isn't really fair-play), a hint: it's not Mark Fidrych. 8) Okay, that's not a very good hint, but Fidrych was one of the guys I had in mind when I did the search. This guy *did*, however, play at the same time as Fidrych, and I think they faced off once or twice while this guy was with the Red Sox.
