For whatever reason, sometimes I am only able to find one card of certain players. To be considered a One-Card Wonder, a player must have been active since 1991 (when I started paying attention).
Sorry folks, another one with no scan. This one is a 1998 Pacific Online card, a great set for team collectors because it featured a bunch of cards of guys that had few, if any, other cards. You'll see this set again in this series.
I am not totally sure why Jim Corsi has no other Red Sox cards. He was a major part of the Red Sox bullpen for two years in 1997-1998. He also pitched in 1999 and accumulated 134 games over the course of the three seasons for Boston. Corsi went 9-7 with two saves. He pitched to the tune of a 3.35 ERA for the Red Sox. He also struck out 103 in 147.1 innings.
EDIT: I just recently picked up one of the parallels of this card.
