NEW YORK — Andy Roddick is not ready for retirement yet.
A day after surprisingly announcing the U.S. Open will be the last tournament of his career, Roddick dominated Australian Bernard Tomic from start to finish Friday night and reached the third round with a 6-3, 6-4, 6-0 victory.
Roddick, the 2003 U.S. Open champion, plays at least one more time, against 59th-ranked Fabio Fognini. "I'm going to try to stick around a little longer," Roddick said during an on-court interview with one of his former coaches, Brad Gilbert.
Roddick turned 30 Thursday and held a news conference to say he would quit after a season of injuries and poor Grand Slam results. But he looked good against 43rd-ranked Tomic, 19, hitting 13 aces, including on the final point.
Asked whether he got emotional preparing for the match, Roddick said: "Had a rough patch there, about 15 minutes before. … Made the mistake of walking by one of the TVs while they were doing slow, dramatic things (recapping his career). I assume it was set to an '80s ballad. It got me a little bit."
Also on the men's side, Tampa resident and ninth seed John Isner advanced to the third round, beating Jarkko Nieminen 6-3, 6-7 (5-7), 6-4, 6-3. Defending champ Novak Djokovic beat 112th-ranked Rogerio Dutra Silva 6-2, 6-1, 6-2.
Maria Sharapova, the No. 3 seed, ended the run of Stanford All-American Mallory Burdette, 6-1, 6-1. But the big topic at her news conference was her saying she is no longer engaged to former NBA player Sasha Vujacic.
Sharapova said their relationship has been over "since the end of spring, actually." The couple met in October 2009 and became engaged a year later.
Vujacic was a first-round draft pick of the Lakers in 2004 and played for them until being traded to the Nets in 2010-11, then left the NBA to play in Turkey. Sharapova said their schedules made it "extremely difficult" to see each other.
"We have a tremendous amount of respect for each other. Still would love to call him a friend," Sharapova said. "We spent really great years together."
Defending champ and Tampa resident Sam Stosur dominated the second set against No. 31 seed Varvara Lepchenko for a 7-6 (7-5), 6-2 victory. She faces 18-year-old Brit Laura Robson, who eliminated ninth seed Li Na 6-4, 6-7 (5-7), 6-2 two days after ending Kim Clijsters' singles career.
Top-ranked Victoria Azarenka had no trouble with 28th-ranked Jie Zheng, winning 6-0, 6-1.
Clijsters, who says she is retiring for good after the Open, also has at least one more match. She and mixed doubles partner Bob Bryan won in the first round. She lost in women's doubles Thursday.
Late Thursday, Venus Williams lost to Angelique Kerber 6-2, 5-7, 7-5. "All I had was fight, because I didn't play well," Williams said.
