He had Tommy John. I think they'll try to build up his arm and stamina by seeing how he deals with a reliever role. He has the body of a starter (6'6, 235+) but the problem is whether he has the conditioning and arm strength to play starter after so much time on the shelf.
I'm put him in the 8th inning spot to cover for Joba so he can move to the rotation (problem solved hopefully)
