I have to say that trying to convert Vinnie to a short reliever in the majors, on a contender, doesn't make a lot of sense to me. Even assuming that VV can make the transition, asking him to do it in the majors, against the best team in the league?
If they mean to make this conversion, they need to think about the best way to make it work - which IMHO would entail Vince working in AAA in the relief role until he's at least somewhat comfortable there. But throwing him in cold, against the Dodgers?
