The Pittsburgh Pirates announced on Friday night that outfielder Jason Martin recently underwent surgery to repair a left shoulder labral tear. The typical full recovery time is 4-6 months, which would place him at 100% some time between the start of Spring Training and the middle of April.
Martin was injured on a play at the plate on September 3rd, shortly after he joined the Pirates as a September call-up. At the time, it was announced that he had a dislocated left shoulder. The initial report from the Pirates said that he would have been out for four weeks, which meant he would miss the rest of the season, but still have a healthy off-season. Things have obviously changed over the last six weeks and now this short-term injury is now a long-term issue and will force him to spend much/all of his off-season in rehab mode.
