Red Sox right fielder JD Drew underwent a surgical procedure on his left shoulder on Thursday at Mass General, a baseball source confirmed. The surgery was first reported by the Boston Globe. The procedure was described by the source as “minor.”

Drew received pain-relieving cortisone injections in the AC joint of the shoulder in both June and again in the final days of the regular season. Despite the condition, he played in 137 games, and hit .279 with a .392 OBP, .522 slugging mark and .914 OPS that ranked second among A.L. outfielders.
