MELBOURNE -- Top-ranked Roger Federer advanced to the third round of the Australian Open today with an emphatic, 6-1, 6-4, 6-0, victory over Florian Mayer.
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. ''I thought I handled it well in the heat -- I'm very happy with my performance."
US Open women's champion Kim Clijsters spent 10 minutes longer on court than Federer in her 6-4, 6-2 victory over qualifier Yuan Meng.
Clijsters, bothered by hip and back soreness, overcame 48 unforced errors and five double faults to beat Yuan, who had heavy strapping on both thighs and produced only two clean winners in the match.
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.
Third-seeded Amelie Mauresmo advanced with a 7-6 (7-1), 6-2 win over French compatriot Emilie Loit, and 2004 French Open winner Anastasia Myskina had a 7-6 (7-4), 0-6, 6-3 victory over Jamea Jackson.
Seventh-seeded Patty Schnyder beat Shinobu Asagoe, 6-1, 7-6 (9-7).
Federer was so dominating that Mayer never had a game point after holding serve to pull to 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 lovely 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.
No. 5 Nikolay Davydenko, a potential quarterfinal rival for Federer, advanced, 4-6, 6-0, 6-3, 6-2, over Kevin Kim.
In women's matches, 17-year-old Michaella Krajicek defeated India's Sania Mirza, 6-3, 7-5, and Australia's Samantha Stosur beat Ana Ivanovic by the same score.
No. 16 Nicole Vaidisova and No. 20 Flavia Pennetta were other seeds advancing.
Mirza became 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 US 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.
Yesterday, defending women's champion Serena Williams had a 6-3, 6-1 victory over 130th-ranked Camille Pin to reach the third round.
Williams gave up only three points in the last three games in running her winning streak here to 16 matches. She won the title in 2003 and 2005, and skipped the 2004 tournament because of injuries.
''The last two times I played here, I did really well," she said. ''I'm just hoping to keep it up."
Top-ranked Lindsay Davenport, the 2000 Australian champion, had to scramble in defeating Croatia's Karolina Sprem, 7-6 (7-4), 6-3.
Maria Sharapova overcame 31 unforced errors and fended off three set points against American qualifier Ashley Harkleroad in the second set to advance, 6-1, 7-5.
French Open champion Justine Henin-Hardenne, seeded eighth, took the last five games after Hana Sromova turned her ankle badly and won, 7-6 (7-2), 6-1.
Also advancing were No. 6 Nadia Petrova and No. 14 Svetlana Kuznetsova, the 2004 US Open winner. Among the men, No. 2 Andy Roddick and No. 4 David Nalbandian moved on.
