(Newser) – America's best male tennis player of the last decade is about to throw in the towel, reports USA Today. The US Open now under way will be Andy Roddick's last tournament. "For 13, 14 years, I was invested fully," he said today. But "I don't know if I'm healthy enough or committed enough to continue another year." Roddick, married to model/actress Brooklyn Decker, turned 30 today.

He first became world No. 1 in 2003; that year, at 21, he was the youngest American to end the year in the top spot. (His victory in the US Open in '03 remains the last time an American male has won a Grand Slam singles title.) He's the owner of 32 ATP World Tour titles and 33 Davis Cup wins. He's been in the Wimbledon final three times—each time losing to Roger Federer, most recently in 2009. This year, "walking off at Wimbledon, I felt like I knew," he said. "I don't want to disrespect the game by coasting home." See more at Bleacher Report.
