LONDON, June 26 (Agencies): Serena Williams has been known to say she isn�t satisfied with this or that aspect of her game, even after easily winning a match, say, 6-3, 6-2. So it was somehow refreshing to hear Williams actually praise herself after a victory by that very score over 26th-seeded Maria Kirilenko at Wimbledon on Saturday.
She was part of a parade of past champions who breezed into the fourth round on Saturday, joined by Roger Federer, Rafael Nadal and Maria Sharapova, who all were straight-set winners, too. Top-seeded Caroline Wozniacki, seeking her first Grand Slam title, and two-time Australian Open champion Novak Djokovic, who is now 44-1 in 2011, also moved on.
There were two upsets of some significance.
Two-time French Open finalist Robin Soderling, who was seeded fifth, was dealing with stomach problems and bowed out meekly against 158th-ranked qualifier Bernard Tomic of Australia 6-1, 6-4, 7-5. Tomic is the first 18-year-old to reach the men�s fourth round at Wimbledon since Michael Chang and Goran Ivanisevic in 1990.
�I was very calm, but inside I was bursting. I tried not to show it to him. He was getting a bit frustrated,� Tomic said. �The way I�ve been playing is really good. If I can keep it up like this, who knows?�
No. 9 Gael Monfils lost to 93rd-ranked qualifier Lukasz Kubot of Poland 6-3, 3-6, 6-3, 6-3. Kubot is the first man from Poland to make it this far at Wimbledon since Wojtek Fibak in 1981.
Wimbledon is the only Grand Slam tennis tournament that schedules a day off on the middle Sunday � and the only one that puts all 16 men�s and women�s fourth-round matches on the second Monday. When play resumes, these are some of the men�s matchups: No. 1 Nadal vs No. 24 Juan Martin del Potro, the 2009 US Open champion; No. 2 Djokovic vs No. 19 Michael Llodra; No. 3 Federer vs No. 18 Mikhail Youzhny; No. 4 Andy Murray vs No. 17 Richard Gasquet; and No. 10 Mardy Fish, the last US man left, vs No. 6 Tomas Berdych, the 2010 Wimbledon runner-up.
Fish advanced on Saturday when Robin Haase retired in the fourth set, while Berdych wrapped up a rain-suspended victory over Alex Bogomolov Jr. of the United States.
�It�s lonely,� said Fish, who�s been broken only once in three matches. Djokovic trashed his racket during a 6-4, 4-6, 6-3, 6-4 victory over 2006 Australian Open finalist Marcos Baghdatis in the day�s last match on Centre Court.
�Look, I�m not going to change who I am. I can work on some things, but, you know, my temper is my temper. My character is my character,� said Djokovic, whose 43-match winning streak ended with a loss to Federer in the French Open semifinals.
With Baghdatis serving at 30-all while leading 4-3 in the second set, Djokovic pushed a shot long to lose the point. Standing at the baseline, he smashed his racket, hitting it once, twice, three times against the ground. As Djokovic walked to the sideline to trade in that now-damaged piece of equipment for a fresh one, Baghdatis chuckled to himself.
Chair umpire James Keothavong � brother of British player Anne Keothavong � was less amused, warning Djokovic for racket abuse.
