NEW YORK -- Andy Roddick will retire after the U.S. Open, he said in a news conference Thursday.
"It's a matter of how I feel, and if I feel I can compete at the highest level," he said of his decision.
Roddick has 32 career titles and won the Open in 2003 for his only major title. He's currently ranked No. 22 in the world.
When asked about his career, the former No. 1 said, "I don't know that I would want to change much."
The 20th-seeded Roddick is scheduled to play Bernard Tomic in the second round on Friday night at Arthur Ashe Stadium.
The American's surprising decision to walk away from the sport comes a day after four-time major champion Kim Clijsters played the last singles match of her career, a second-round loss to Laura Robson at Flushing Meadows.
Roddick celebrated his 30th birthday on Thursday.

So what are your thoughts on Andy Roddick's career?
Most people look at Roddick's career as a disappointment since he only won one Grand Slam after having so much hype behind him because of his serve, but I completely disagree. Could he have done a better job developing an all around skill set? Absolutely, but he still had a wonderful career if you ask me.
People who discredit him for only win one Grand Slam fail to realize a couple of things. The first thing is that he reached reached four other Grand Slam finals. And the 2nd thing is, he did that during the era of Roger Federer and Rafael Nadal... two serious GOAT contender. And lately he's also had to deal with Novak Djokovic, who undoubtedly has an unbelievably great future ahead of him.
For Roddick to accomplish what he has during this era is extremely impressive, and I don't think many others throughout history could have done much more against Federer and Nadal in their prime.
Also, let's face it... Roddick has been the only American male tennis star worth a damn for ten years now. Without him, American male tennis would have been the shits. He at least gave us someone to root for during every Grand Slam, and he competed his ass off.
I'll say the only major disappointment about his career is the 2009 Wimbledon loss, which in my opinion is what broke him. Since then he has not been the same, and you can't blame him. That was one of the most heartbreaking losses in the history of sports, period. Had he won that... not only do I think he would have competed better these last couple of years, but his legacy would have been much more respected than it probably will end up being.
Regardless of what others think though, Andy Roddick has my respect and my full support during this US Open. I'm definitely rooting for him to go out with a bang. If he doesn't, then that's fine; he's still had a hell of a career as far as I'm concerned.
