Olympic gymnast Paul Hamm announces he's retiring

WAUKESHA (AP) -- Paul Hamm, the only U.S. man to win a world or Olympic all-around title, is retiring.

Hamm told The Associated Press on Tuesday he is abandoning his comeback for the London Olympics because his body can no longer handle the demands of training and competition. He says "your mind wants a certain outcome ... but you can't get your body to perform a certain way."

Hamm had surgery in January 2011 to repair a torn right labrum and rotator cuff.

The announcement comes four months to the day before the London Olympics start. Hamm returned in June 2010, hoping to end his career with a positive Olympic experience after a judging controversy spoiled his Olympic title in 2004 and a freak injury forced him out of Beijing.

Hamm retires with five medals from the world championships and three from the Olympics, including all-around titles at the 2003 worlds and 2004 Summer Games.
