Stosur blitzes Wozniacki in Doha

The Australian, who lost in the final of the French Open, is now on the verge of a place in the last four after storming to a 6-4 6-3 win in 87 minutes.

Although Wozniacki found it hard to live with her opponent's thundering groundstrokes, she did create opportunities of her own - but she squandered six chances to break.

Kim Clijsters recorded her seventh victory in eight attempts against a flagging Jelena Jankovic. With Jankovic clearly still suffering with the sinus problems that have affected her for months, the Belgian cruised to a 6-2 6-3 triumph.

It is another setback for Jankovic who, sinus issues aside, has struggled to find any semblance of form since Wimbledon. The Serb has now lost 16 of 25 matches played since her exertions at SW19 in the summer.

Clijsters, playing at the WTA Championships for the first time since 2006, took advantage of her opponent's woes in ruthless fashion. She won 29 of 45 points in a completely one-sided first set - with a 100% break-point conversion rate - and lost a mere three points on her first serve.

The second frame was more closely fought, but Jankovic's resistance was decisively wounded in the fifth game when Clijsters snatched a crucial break. "I'm not happy with everything I did today but I will try and remember the positives and take them forward to tomorrow's match," Clijsters said. "I want to be a bit more consistent, hit a few less double faults and try to remember the good things."

Vera Zvonareva took a huge step towards making the semi-finals by defeating Victoria Azarenka in straight sets. In a low-quality match - there were 66 unforced errors in all - Azarenka threw away a lead in both frames before falling to a 7-6(4) 6-4 defeat.
