Caroline Wozniacki was dumped from the Sydney International yesterday, opening the way for rival Petra Kvitova to seize the world number one ranking heading into next week’s Australian Open.

Wozniacki crashed out to Polish world number eight Agnieszka Radwanska, 3-6, 7-5, 6-2 in the quarter-finals after being broken while serving out for the match at 5-4 in the second set.

Radwanska will now face Bela-russian third seed Victoria Azarenka in today’s semis, with Kvitova lining up against Chinese defending champion Li Na in the day’s other semi-final.

Wimbledon champion Kvitova had an emphatic straight sets victory over Daniela Hantuchova, while world number five Li downed Czech Lucie Safarova 6-2, 7-6.

Kvitova is on track to take the number one ranking by winning the tournament.

Wozniacki, whose tenure at the top of the women’s singles rankings comes despite not yet winning a grand slam in 19 attempts, was taken to a third set by Radwanska after appearing to be in a winning position.

The Dane seemed troubled by a wrist injury as Radwanska broke her three times in the final to claim only her second win in seven meetings.

Earlier, Kvitova reeled off the opening eight games before dishing out a 6-0, 6-4 victory over Hantuchova, the Slovak number 21.

Kvitova, who like Li has been in top form in preparation for the season’s first grand slam in Melbourne, swept to victory breaking Hantuchova’s service five times for her fourth win over the Slovakian.

“I was surprised that I played well. In these (windy) conditions it’s very tough to play,” Kvitova said.

“Yeah, I’m still on the track. But still it’s two matches, and the next one is really tough against Li Na,” Kvitova said.

“She is tough opponent. She’s in top five, so it will be a good match.”

Li said she was playing her best tennis since before last year’s Wimbledon as she battled into the semi-finals.

The world number five needed one hour 50 minutes to subdue battling Czech Safarova in blustery conditions to move into the last four in the defence of the Sydney title she won last year.

It was Li’s third win this week, continuing her upsurge in form after a dismal follow-up to her landmark French Open success at Roland Garros, which saw her become the first Asian to win a grand slam title.

Belarussian Azarenka downed France’s Marion Bartoli 7-5, 6-4 in their quarter-final.
