Andy Roddick called it quits on his 30th birthday.
The 2003 U.S. Open champion — and the last American man to win a Grand Slam singles event — announced Thursday that the U.S. Open will be his final tournament.
Roddick will play Australian Bernard Tomic in Friday's night session in Arthur Ashe Stadium in what could be the final match of his career.
"I have decided that this is going to be my last tournament," Roddick said. "I don't know if I'm healthy enough or committed enough to continue another year.
"For 13, 14 years, I was invested fully. … I have been pretty good about keeping my nose to the grindstone. I feel like I've won a lot of matches by being consistent."
John McEnroe, a seven-time Grand Slam champion, said of Roddick on ESPN: "I didn't think by any means he would do it on his 30th birthday. That's a jarring birthday. ... Physically, it seems like the wear and tear has caught up with him."
Roddick won 32 career ATP World Tour titles, including two this season, and has earned more than $20 million. He was the youngest American (21 years, 3 months) to end the year at No. 1 in the world (2003).
Roddick is a three-time Wimbledon finalist (2004-05, '09), losing to Roger Federer each time. The 2009 final ended 16-14 in the fifth set.
Federer, Rafael Nadal and Novak Djokovic combined to win 29 of the last 30 majors.
"As much as I was disappointed and frustrated at times, I'm not sure that I ever felt sorry for myself or begrudged anybody any of their success," Roddick said.
Roddick is married to model and actress Brooklyn Decker, and he made a cameo appearance in her recent movie, "Just Go With It."
Roddick, who has battled injuries the last couple of years, including this year, said he felt it coming at Wimbledon, when he waved to the crowd after his last match.
"Walking off at Wimbledon, I felt like I knew," he said. "I don't want to disrespect the game by coasting home."
