Obviously, I'm no pitching coach, but I highly doubt Suppan's problems were related to mechanics. When I watched him pitch this year, his stuff looked fine, for the most part (in relative Jeff Suppan terms). Some pitches even showed some decent movement. His problem, like many soft tossers, is that he has to nibble at the corners to get people out, and when he isn't able to get ahead of hitters that way, he has to serve meatballs right over the heart of the plate. Unfortunately for Suppan and the Brewers, his stuff at this point in his career is worse than most soft tossers and even when he doesn't groove one down the middle, hitters are often able to size up his pitches and line them somewhere.
