"Dr. Andrews was pleased with the results of the surgery and noted that the rest of Kevin's shoulder was sound," general manager Neal Huntington said.
There is approximately a nine-month recovery period for this type of surgery, which has the Pirates optimistic that Hart will be healthy by the start of Spring Training next February. He will head to Bradenton, Fla., soon to start the rehabilitation process.
Tuesday's surgery brings an end to a frustrating and disappointing 2010 season for Hart, who came into camp this spring with the upper hand at winning the fifth spot in Pittsburgh's rotation. He pitched his way out of that job and then allowed 13 earned runs on 18 hits in 17 1/3 innings with Triple-A Indianapolis in April.
