Serena Williams tops WTA world rankings, Federer moves up to number 2 in ATP men's list

Paris: Serena Williams continued to dominate the WTA rankings despite being sidelined with an injury to her left knee.

The 33-year-old American was forced to abandon her defence of the China Open earlier this month due to the injury, with second-ranking Maria Sharapova going on to win the tournament.

But she is still nearly 2,000 points clear of the Russian atop the rankings.

Injury has also blighted Canada's Eugenie Bourchard as she had to pull out of her second round tie in Linz last week.

That meant she dropped down one spot in the rankings from sixth to seventh with Agnieszka Radwanska of Poland moving ahead of her.

The 33-year-old Swiss star is more than 3,000 points behind top-ranked Novak Djokovic, but he did have the satisfaction of defeating the Serb in straight sets in the Shanghai semi-finals.

Rafael Nadal moves down to third in the rankings with Australian Open champion Stan Wawrinka staying at fourth despite an early exit in China to Gilles Simon.

The Frenchman went on to reach the final where he lost to Federer and that was enough to hoist him up 11 places to 18th.
