It depends. If we can sign a starter that can throw better than Wainwright, then I wouldn't mind him spending some time in the 'pen. I think that two years seems to be a far more realistic timeframe for recovery than just one. So yeah, I'd be happy to see him throw in relief to get some time in while he gets his old arm all the way back. But only if we'd somehow be able to replace him with someone better than he is.
And having said that, I don't think his stats are completely indicative of his performance. The team just seems to hate him--and it was even like that two years ago. It's like the bats shut down and the defense naps whenever he's on the mound. I'd be more than a little perplexed if I were him. It's almost like he needs to be near-ace-level to get a win out there.
