NEW YORK -- Mariano Rivera will have surgery on his injured right knee June 12, the New York Yankees' closer said Wednesday.

The surgery will be performed by Dr. David Altchek, the New York Mets' team physician, and Rivera expects to be ready to pitch again by the start of next season.

"Oh yeah, there's no doubt about that, God willing," Rivera said Wednesday afternoon before the Yankees' game against the Tampa Bay Rays.

The 42-year-old Rivera tore the anterior cruciate ligament and damaged the meniscus in his right knee while shagging fly balls in the outfield May 3 before a game in Kansas City. He would have had the surgery sooner, but doctors discovered a blood clot in his right calf after the knee injury.
