Wozniacki stays put
Denmark's Caroline Wozniacki remains on top of the women's singles rankings, which were released on Monday, in spite of her failure once again to land a Grand Slam title.
The 20-year-old has now spent 38 weeks in the number one position but has only ever reached one Grand Slam final -- the US Open in 2009 -- and was knocked out in the fourth round at Wimbledon.
Petra Kvitova's reward for winning Wimbledon was a move up one place to seven in the world, while the woman she beat in the final, Maria Sharapova, also edges up one place to number five. French Open champion Li Na slips two places to number six.
