In Regards to Manny Parra? I have to tell you that he has moved back into the general direction of the lefty pitcher with upside. If you look at his BAbip from last year, there is reason to believe that he will be better this year. And he has been better at limiting his baserunners in the small sample size. His WHIP is 1.25 for the spring. He's currently locked in a matcuhp with Dave Bush for the 4th starter.
Right now? Bush has shown the better stats. And I think if the Brewers aren't going to do anything with Suppan? The place where he can do the least damage is as the 5th starter. So the loser goes into the Seth McClung long relief role. In short. Hold. But be ready to drop him at the first sign of a sexy waiver pickup if he doesn't start hot.
