Ugh, that's not a pretty picture.
Have you sorted the pitchers by their Yahoo rank and their last month stats? I know that the Yahoo rank isn't perfect, but it will help separate the chaff from the wheat. I really can't recommend any
of those pitchers.
What about relievers? Are there any good middle relievers available that might help you? I'm thinking of the Joe Nathans, The Motas, etc. Those guys are probably taken, but perhaps there is someone, anyone, out there that would help.
