192 - Tom McGraw (Major League Games: 2. The odd thing is, he didn't make the majors until 1997 with the Cardinals and retired with a career 0.00 ERA in 1 2/3 IP.)
244 - Arthur Rhodes (Major League Games: 833 and still counting! I wonder how many other active players are in this set.)
If you're into minor league cards, especially from the early '90s, I implore you to check out The Greatest 21 Days. Great stuff.
