SAN FRANCISCO -- The A's announced Friday that right-hander Jarrod Parker underwent successful surgery on his right elbow, though the 27-year-old's Major League future remains in doubt.
Parker, who has endured two Tommy John elbow surgeries, underwent the procedure Wednesday in Los Angeles, two days ahead of the previously scheduled date. Dr. Neal ElAttrache used the previously revised ulnar collateral ligament graft to reconstruct parts of Parker's elbow. The orthopedist also reattached a tendon to the humerus bone and cleaned out bone chips and spurs in back of the elbow.
A's head athletic trainer Nick Paparesta related that Parker, who hasn't pitched in the Majors since the 2013 American League Division Series against Detroit, should be able to begin strengthening his elbow in about three months.
