TAMPA, Fla. — New York Yankees third baseman Alex Rodriguez underwent arthroscopic surgery yesterday to repair torn cartilage in his right hip, and doctors said they found nothing that would keep him from returning to the lineup in May.

"The surgery went exactly as we planned," said Dr. Marc Philippon, who performed the 80-minute procedure at Vail Valley Surgery Center in Colorado. "No surprises."

Other options considered were a more aggressive surgery that would have sidelined Rodriguez up to four months or a conservative approach of rest and treatment.

"There is no doubt in our minds that this was the best option," Philippon said.

General manager Brian Cashman expects the three-time AL MVP back on the field "sometime in May." Rodriguez will need a more extensive operation after the season, and Philippon said Rodriguez will "absolutely" be ready for spring training in 2010.

Rodriguez was expected to be released from the hospital later yesterday and to start his rehabilitation. He was to perform range of motion drills and ride a stationary bike.

"Alex is doing well," Philippon said. "Over the next few days, until Friday, we will work on his range of motion. Hopefully by Friday or Sunday, we will start working on his muscle memory and adding range of motion that involves the rotation of a batter when he swings."
