I think this is a terrible signing. The absolute best case scenario is that he is an average pitcher. More likely is that he is a new Jason Marquis. The Twins shouldn't spend $10 million for that. If you are aiming for mediocre, get some cheap AAAA cast-off guys. There are pitchers who are riskier but who have a much better upside. The Twins should target them. That way, if they fail, cut bait. If they succeed (ala Diamond), re-sign them.
