Pre-1980: 1972 Topps 167 Deron JohnsonDeron was acquired by the Phillies in 1969 and was a big offensive force for them. But he only played 96 games in 1972 and was traded in 1973 to the A's for somebody you never heard of.
1980s: 1982 Fleer #267 Dick Ruthven
Dick was 11-11 with a 3.79 ERA for the 1982 Phillies.
1990s: 1998 Fleer Tradition #309 Curt Schilling
Curt was 15-14 for the 1998 Phillies. He led the league in starts, with 35, complete games, with 15, and innings pitched, with 282. He was a workhorse.
2000s: 2008 Ultra Gold Medallion #119 Ryan Howard
I think that Ryan is one of the few players who holds up his bat like this before each pitch. I have a lot of cards featuring this pose.
