I realize that this includes a current player but I think it fits better here. They are both very similar players in that they had relatively short, yet nothing short of Hall of Fame standard, peaks. Pedro Martinez '97-'03 118-36 (20-6/Season) 2.58ERA, 1,761K's (294K's/Season), ERA+251 Sandy Koufax '61-'66 129-49 (26-10/Season) 2.69ERA, 1,713K's (343K's/Season), ERA+ 193 Pretty eerily similar numbers over those stretches. The difference being that Koufax was in his prime when he was forced to retire due to arthritis, Pedro has shown his sign of age when hes pitched lately, or maybe more importantly when he hasn't pitched. Who would you take when they were in their prime and who do you think is/was better? My pick would be Pedro, and not just because I'm a Sox fan, I'll take the ERA over the W's and K's anyday. Because chances are that if Koufax ERA has been the same as Pedro, not that his was bad, he would've won even more games and had fewer losses.
