Corey Kluber exited today’s rehab start with the Columbus Clippers after one scoreless inning of work. According to a contributor for Sox Machine, Kluber didn’t seem thrilled heading into the dugout and was replaced with Jared Robinson in the second inning.
There’s no official word on the injury yet, but Andre Knott has reported that it’s tightness in his side and nothing to do with his arm.
Of course, we have no idea if that tightness is from overcompensating because something is hurting in his arm, or maybe it’s just a regular old muscle spasm.
