SAN FRANCISCO (AP) Oakland right-hander Jarrod Parker underwent successful surgery on his right elbow, the Athletics announced before Friday night's exhibition game with the San Francisco Giants.
The surgery was performed by Dr. Neil ElAttrache in Los Angeles on Wednesday. Dr. ElAttrache, using Parker's revision UCL graft that was done two years ago, reconstructed the medial compartment of Parker's elbow, including reconstructing the flexor tendon and ulnar collateral ligament complex. Parker returns to Arizona on Saturday.
Parker had his second Tommy John surgery in March of 2014 and hasn't pitched in the majors since the 2013 AL Division Series. He re-fractured his medial epicondyle during a simulated game on March 10 after originally fracturing it last May while pitching for Triple-A Nashville.
His previous revised UCL did not need repairing and the avulsed medial epicondyle fracture was cleaned up and repaired.
