From what I understand Zambrano will still pitch in the first rotation. If that turns out to be wrong I am guessing they would use Heilman at this point. Lima is a possibility but he hasn't really looked all too good.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
