Dr. George Paletta, the team's head physician, performed the procedure. Paletta has a lengthy and successful track record with the ligament replacement surgery. He performed the same operation on Cardinals pitchers Chris Carpenter, Jaime Garcia and Kyle McClellan, among many others.
The club announced during Monday's Spring Training game against the Marlins that, according to general manager John Mozeliak, "the surgery went very well." Wainwright is expected to remain in St. Louis for about two weeks before returning to Florida to join his teammates at camp.
Wainwright, 29, went 20-11 with a 2.42 ERA in 2010, striking out 213 against 56 walks in 230 1/3 innings. He finished second to Roy Halladay in balloting for the National League Cy Young Award.
The typical rehabilitation time for a starting pitcher who has Tommy John surgery is approximately 12-15 months.
