Phil Dumatrait?

I know he was just promoted to AAA a few weeks ago, but he's done well there so far. I would give him a couple more starts in Louisville and then assuming Joe Mays is not the answer, let him have his shot after the all star break. I know he is still young, but not as young as Homer or any of the others, and worst case scenario it would be better than bringing up (and ruining) any of the youngsters.
