I think you're being way too generous with a 5.75 ERA. With most pitchers, I would agree as they may regress as time goes on, but it would be in smaller increments. With Suppan, his regression seems to be getting exponentially worse by the season. Watching him this year, I have no confidence that his ERA would be any less than 7.00 if he pitched all year. That's not just my disdain for Suppan coloring my view of his outlook. I see nothing in his pitching that could sustain an ERA less than that. His velocity, movement and control are all falling off a cliff, and this team's hopes of getting to the playoffs are following Suppan's skills with every start he makes.
