TAMPA, Fla. -- Alex Rodriguez underwent successful surgery on his right hip on Monday and is expected to return to the Yankees' lineup within six to nine weeks.

Dr. Marc Philippon performed the one-hour, 20-minute procedure at the Vail Valley Surgery Center in Vail, Colo., and said that Rodriguez would be able to check out of the hospital later in the day.

"Alex is doing very well," Philippon said on a conference call with reporters. "The surgery went exactly as planned, and we will start him on his rehab this afternoon."

Philippon said he repaired a torn labrum in Rodriguez's right hip and also addressed cartilage from a paralabral cyst, both of which had restricted Rodriguez's movement dating back to last season.

"There were no surprises," Philippon said. "It was exactly what we prepared for."

Rodriguez will be on the fast track to returning to baseball shape, beginning range-of-motion exercises and riding a stationary bicycle later Monday.

Rodriguez will continue working on muscle exercises using small resistance for the rest of the week, and by Sunday, he could begin handling a bat.

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

In medical terms, Rodriguez's labrum tear was a femoroacteabular impingement, which causes friction in the hip joint. Rodriguez had two types of impingement, "pincer" and "cam."

Philippon repaired only the pincer impingement on Monday, a so-called "hybrid" procedure. Rodriguez will eventually have another procedure performed, one the Yankees hope will take place after the season.

Philippon said that because Rodriguez had Monday's procedure, the rehabilitation time of the later procedure will be shorter than the three to four months he could have missed by having it now.

Philippon said that if Rodriguez has the surgery in November, he "absolutely" would be ready for Spring Training in 2010.

Rodriguez had been managing tightness and discomfort in his right hip dating back to the 2008 season, though he had never complained of pain.

An MRI taken on Feb. 28 in Tampa, Fla., showed changes to an underlying bone deformity first cataloged by the Yankees last May, when Rodriguez spent time on the disabled list with a strained right quadriceps. That prompted Yankees team physician Dr. Chris Ahmad to recommend that Rodriguez be sent to a hip specialist.

With Rodriguez sidelined until at least mid-April, the Yankees plan to fill their lineup from within. Cody Ransom is the most likely candidate to fill in at third base for the three-time American League Most Valuable Player, who is in the second year of a 10-year, $275 million contract.

"We're going to miss him -- that's the bottom line," Yankees manager Joe Girardi said. "I'm glad things went well, the surgery. One thing about Alex, we know he's going to work and work and work. It might be a case where you have to hold him back a little bit, because he's going to be anxious to get back. Alex is not replaceable, but they said six to nine weeks, and hopefully it's fairly soon."
