Curt Schilling, RHP
Career: 1988-2007, Orioles, Astros, Phillies, Red Sox, Diamondbacks
Fun fact: Career 2.23 postseason ERA
Your opinion of Schilling probably has a lot to do with how much you think October performance should be weighted, as he is arguably the greatest postseason pitcher ever, with legendary performances -- such as The Bloody Sock Game -- to match his numbers.
And he's no regular-season slouch either. A known workhorse, Schilling twice led the league in innings pitched.
