TOKYO -- Top-seeded Dane Caroline Wozniacki and two- time 2010 Grand Slam finalist Vera Zvonareva of Russia were among Tuesday's second-round winners at the $2 million Toray Pan Pacific Open.

The former U.S. Open runner-up Wozniacki waltzed past Hungarian qualifier Greta Arn 6-1, 6-3, while the second-seeded Zvonareva zipped past Italian Sara Errani 6-3, 6-3 on the hardcourts at Ariake Colosseum.

The surging Zvonareva was this year's runner-up at the U.S. Open and Wimbledon.

A top-five upset came when German Julia Goerges grounded fourth-seeded French Open runner-up Samantha Stosur of Australia 7-5, 6-3.

Fifth-seeded French Open champion Francesca Schiavone and former Pan Pacific titlist Elena Dementieva also posted wins on Day 3. The Italian Schiavone beat Romanian Alexandra Dulgheru 7-5, 6-3, while a seventh-seeded Dementieva drubbed Kazakhstan's Yaroslava Shvedova 6-0, 6-1. The Russian Dementieva captured this Tokyo tournament back in 2006.

Meanwhile, eighth-seeded Belarusian Victoria Azarenka drilled Czech Lucie Safarova 6-1, 6-3 and German Andrea Petkovic toppled 10th-seeded Svetlana Kuznetsova 6-3, 7-5. The two-time major champion Kuznetsova was the Pan Pacific runner-up in 2008.

In other action involving seeds, No. 11 Marion Bartoli whipped former world No. 1 Ana Ivanovic 6-2, 6-1; Estonian Kaia Kanepi upended No. 13 Israeli Shahar Peer 6-3, 7-6 (7-5); American qualifier Coco Vandeweghe erased No. 14 Frenchwoman Aravane Rezai 6-4, 6-4; and No. 16 Russian Anastasia Pavlyuchenkova routed Ukrainian Kateryna Bondarenko 6-2, 6-1. Ivanovic was a Pan Pacific Open runner-up in 2007.

Additionally, 40-year-old Japanese Kimiko Date Krumm got past Slovakian Daniela Hantuchova 2-6, 6-0, 4-0, Italian Flavia Pennetta held off Russian Maria Kirilenko 6-3, 4-6, 6-3, and Italian qualifier Roberta Vinci vaulted past Bulgarian Tsvetana Pironkova 6-4, 6-2. Date Krumm, who captured this title in 1995 and celebrated her birthday here on Tuesday, was leading Hantuchova in the third set when the Slovakian retired with a shoulder injury.

Some of Wednesday's third-round matches will pit Wozniacki against Pavlyuchenkova; Zvonareva versus Vinci; third-seeded Jelena Jankovic against Kanepi; Schiavone versus the age-defying Date Krumm; and Dementieva against Pennetta. Jankovic was last year's Pan Pacific runner-up to Maria Sharapova, who was stunned by the wild card Date Krumm here on Monday.

The 2010 Pan Pacific Open champ will earn $350,000.
