Overall I'd put it Clemens, Maddux, Pedro. Clemens recent years of dominance in Houston and Maddux's recent years of average perforance put Clemens over the top. Side point #1: IMO, from his last year at Montreal until his near-4.00 ERA year in Boston, Pedro was the most dominant starting pitcher ever. Side point #2: This kind of surprised me, but of the three, Maddux has the best post-season ERA Clemens: 3.71 Maddux: 3.22 Martinez: 3.40 I didn't know Pedro had a better postseason ERA. I figured Clemens would have the worst of the three though. I don't know about most dominant pitcher ever, but his stretch from 1997 to 2003, like you said, was definately the most dominant stretch of pitching of our generation.
