McGee (elbow) will make his first rehab appearance with High-A Charlotte on Tuesday, Roger Mooney of the Tampa Tribune reports. McGee appears to be progressing well after undergoing arthroscopic elbow surgery over the offseason as he figures to be nearing a return to the big league bullpen. The club hasn't laid out their exact plans for his rehab stint, but the lefty could be back in the majors after only a few appearances in the minors.
