BEIJING -- Top-seeded Caroline Wozniacki was a second-round winner, while U.S. Open and Wimbledon runner-up Vera Zvonareva posted a third-round victory Wednesday at the $4.5 million China Open.
The 2009 U.S. Open runner-up Wozniacki waltzed past Italian Sara Errani 6-4, 6-2, while the second-seeded Zvonareva came from behind to beat fellow Russian Maria Kirilenko 5-7, 6-4, 6-2 at the National Tennis Center. Kirilenko was a champion here in Beijing in 2005.
Wozniacki is fresh off her title last week in Tokyo, where she beat Russian star Elena Dementieva in a marquee finale.
The 20-year-old Wozniacki's third-round opponent on Thursday will be Czech Petra Kvitova, while Zvonareva will encounter French Open champion Francesca Schiavone in Friday's quarterfinals here. The fifth-seeded Schiavone fought back to beat Russian qualifier Vera Dushevina 4-6, 6-3, 6-1 on Day 5.
In other third-round play, 15th-seeded Israeli Shahar Peer pasted Serbian qualifier Bojana Jovanovski 6-1, 6-2 and Swiss Timea Bacsinszky handled Russian Elena Vesnina 6-2, 6-3. Peer and Bacsinszky will square off in the round of eight.
One other second-round match saw German Angelique Kerber blast Romanian Alexandra Dulgheru 6-2, 6-1.
An intriguing third-round match on Thursday will pit the seventh-seeded two- time major runner-up Dementieva against former world No. 1 and former French Open champion Ana Ivanovic.
The 2010 China Open champ will claim $775,500.
