The second-seeded Clijsters needed treatment on her back and hip between sets and was not moving fluently, although she went to the net 14 times and won 12 of those points. “I’m happy with the win but my body doesn’t feel too good at the moment,” Clijsters said. “Although I didn’t play my best tennis, not even close, I always felt like I could win. “As long as (the hip) doesn’t get worse, I’ll keep fighting and see how I go.” Third-seeded Amelie Mauresmo advanced with a 7-6 (1), 6-2 win over French compatriot Emilie Loit, while 2004 French Open winner Anastasia Myskina had a 7-6 (4), 0-6, 6-3 victory over Jamea Jackson. MELBOURNE, Australia — Top-ranked Roger Federer advanced to the third round of the Australian Open with an emphatic 6-1, 6-4, 6-0 win over Florian Mayer today. The 24-year-old Swiss star finished with 38 winners and closed out the 1-hour, 12-minute match with an ace. “It’s so nice to get quick matches in the heat,” said Federer, whose next opponent is 30th-seeded Max Mirnyi. Seventh-seeded Patty Schnyder beat Shinobu Asagoe 6-1, 7-6 (9). Federer was so dominating that Mayer never had a game point after holding serve to pull within 4-5 in the second set. Always a perfectionist, the normally stoic Federer did seem a little annoyed at his 18 unforced errors that accounted for one-third of Florian’s points. And after smacking a forehand crosscourt winner for his third break of the final set, he allowed himself a little fist pump. He finished off the match with two service winners and his eighth and ninth aces, then hit a ball high into the stands. “If I keep on playing the way I am, not losing too much energy out on the court, maybe it’s going to pay back eventually,” said Federer, who has lost only 12 games in the two rounds. The overmatched Mayer tried a little of everything, charging the net and flicking soft drops from the baseline, but nothing worked as temperatures reached 88 degrees. He raised his racket to acknowledge the crowd after winning his first game the sixth of the match. But he became increasingly frustrated, shaking his head and even looking to the sky for help. No. 5 Nikolay Davydenko, a potential quarterfinal opponent for Federer, advanced with a 4-6, 6-0, 6-3, 6-2 victory over Kevin Kim and No. 6 Guillermo Coria overcame Federico Luzzi 7-6 (10), 6-4, 6-3. In women’s matches, 17-year-old Michaella Krajicek defeated Sania Mirza 6-3, 7-5 and Samantha Stosur beat Ana Ivanovic by the same score. No. 16 Nicole Vaidisova and No. 20 Flavia Pennetta were other seeded players advancing. Mirza become the first Indian woman to reach the third round of a major with her breakthrough run here last year. She improved on that at the U.S. Open, where she reached the fourth round. But this time it was Krajicek, a half sister of 1996 Wimbledon champion Richard Krajicek, who made the third round of a major for the first time. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
