Hey Joe, I've been in a similar situation before. What I ended up doing was going to baseball reference, and finding the offensive game logs for that player and year.. Just looking at Jack Armstrong, he had AB's in 29 games in 1990 and it lists the dates, etc. From there you can start an image search. If some of the guys are RP's or only played part of a season it really narrows the focus. Hopefully BMH can get you some good info, but I hope that helps if you need a backup plan.
