Wozniacki rolls into fourth round in Flushing

Flushing Meadows, NY – World No. 1 Caroline Wozniacki round winner Saturday at the 2011 U.S. Open.

The 2009 runner-up waltzed past 103rd-ranked California native Vania King in 6-4, 6-4 fashion at Arthur Ashe Stadium. The Dane advanced in 1 hour, 36 minutes.

The 22-year-old King is now 0-16 lifetime against top-10 women.

The 21-year-old Wozniacki, still seeking her first-ever major championship, leads the WTA with six titles already this year, including a fourth straight New Haven championship last week.

"I won. I think that's the most positive," Wozniacki said. "It's great to be through. You know, I was fighting a lot out there, getting quite a lot of balls back."

King captured doubles titles at the U.S. Open and Wimbledon last year, but has never advanced beyond the third round in singles at a Grand Slam event.

Meanwhile, 2011 French Open runner-up and 2010 Roland Garros titlist Francesca Schiavone staved off a match point before fighting back to beat game South African Chanelle Scheepers 5-7, 7-6 (7-5), 6-3 at the USTA Billie Jean King National Tennis Center.

Scheepers, who is now 0-8 lifetime against top-10 players, was up a set and leading 5-4 in the second when the seventh-seeded Schiavone saved a match point to extend the bout.

Up next for Schiavone will be 17th-seeded Anastasia Pavlyuchenkova of Russia.

Tenth-seeded rising German Andrea Petkovic reached the fourth round at the U.S. Open for a second straight year by handling 18th-seeded Italian Roberta Vinci 6-4, 6-0. The 2011 Aussie and French Open quarterfinalist Petkovic will meet Spaniard Carla Suarez Navarro in her next match.

A mild upset came when the promising Pavlyuchenkova drove out former world No. 1 Jelena Jankovic in straight sets, 6-4, 6-4. The 11th-seeded Jankovic, who has battled injuries in recent weeks, was the 2008 U.S. Open runner-up to Serena Williams.

Also advancing on Day 6 of the fortnight was Suarez Navarro, who handled fellow unseeded Spaniard Silvia Soler-Espinosa 6-0, 6-4.
