From a team release:
RHP Jeremy Hellickson placed on the Disabled List retroactive to 5/6 (Shoulder)…RHP Brian Baker added from Hudson Valley (A-) roster [24 + 2]
Hellickson left his recent start against Birmingham after two innings due to a mild supraspinatus sprain in his right shoulder. Baker was placed on the Hudson Valley roster yesterday in order to make room for OF Jason Perry who was signed by the Rays.
Well, this is just fantastic.
