Jarrod Parker, the Oakland A's pitcher who has been trying to get back on a major league mound after a second Tommy John surgery, re-fractured his medial epicondyle, a bone near his elbow. He originally fractured it last May, while rehabbing in the minors.
This is pretty devastating news for Parker and the A's, and one would think that this could potentially de-rail his career. Parker was a top pitching prospect who was selected #9 overall in the 2007 draft by the Arizona D-Backs, and then sent to Oakland in the Trevor Cahill trade. Parker hasn't pitched in the majors since 2013 -- he didn't pitch at all in 2014, after undergoing surgery early in the year, and made just four appearances in the minors last year before the fracture ended his year.
Parker is still just 27, and Jon Heyman says on Twitter he is going to "keep fighting," but man...at this point, you have to wonder if he'll ever make it back.
