Really depends on the A's and their season heading into July. If the season gets worse they could start moving players which could create one of 2 scenarios: 1) he is dealt in a package 2) other pitchers are dealt and he gets a chance to come up and pitch. Being an A's fan, at this point the rotation and bullpen is set for the time being, but given the recent years of arm trouble on this staff, anything could happen. He also will be battling the pitcher from UF Puk, if he stays in a starter role.
