Australian Open champion Kim Clijsters will move up one spot to No. 2 while Serena Williams, who did not defend her title at Melbourne Park, will drop to her lowest ranking in nearly four years when the new lists are released on Monday.
Rafael Nadal maintains his No. 1 ranking despite his Australian Open quarterfinal loss to David Ferrer, while Caroline Wozniacki held the women’s No. 1 ranking despite losing to China’s Li Na in the semifinals.
Williams, who is recovering from a foot injury, dropped from fourth to 12th, her lowest ranking since March 2007 when she was No. 18.
The 13-time Grand Slam singles winner cut her foot on broken glass after her win at Wimbledon last year.
Wozniacki ensured she’d retain the No. 1 ranking by reaching the Australian Open semifinals, but frequently had to answer questions during the tournament about how she felt holding the top spot without ever winning a major.
“It’s sports. Life goes on,” Wozniacki said after her loss to Li. “I believe if I keep working hard my time will come.”
Vera Zvonareva will drop to No. 3 in the rankings, French Open champion Francesca Schiavone is fourth and Sam Stosur of Australia rounds out the top five.
Venus Williams is sixth, and Li will move to a career-high No. 7 due to her finals appearance in Melbourne.
Venus Williams withdrew four minutes into her third-round match in Melbourne because of an ailing hip muscle. It was the first time in 251 Grand Slam matches she had retired from a major, and the loss caused her to drop out of the top five for the first time in a year.
On the men’s side Roger Federer, who lost to Novak Djokovic in the Australian Open semifinals, is No. 2 behind Nadal. Djokovic, who went on to win the Australian title, remains at No. 3, with Robin Soderling fourth and Melbourne Park runner-up Andy Murray at No. 5.
During the Australian Open, 16-time Grand Slam winner Federer played down the importance of rankings at the top of the game.
“I would say 2, 3, 4, 5, 6 doesn’t really matter a whole lot to me anyway,” said Federer, a longtime No. 1. “Sure it’s better to be No. 2 so you don’t face No. 1 in the semis, but I don’t think the ranking will change my outlook a whole lot.”
