Paris, France – Wimbledon champion Petra Kvitova and reigning French Open champ Li Na were among Thursday's second-round winners at Roland Garros.
Kvitova, the No. 4 seed, handled Urszula Radwanska of Poland 6-1, 6-3 in 70 minutes on Court Lenglen.
The Czech Kvitova denied Maria Sharapova a second Wimbledon crown in last year's finale at the All England Club for her first career Grand Slam title and is trying to better her fourth-round result from last year here in Paris.
"I don't have any expectation. I know that last season was great for me, and it will be very tough to have similar result as last year," Kvitova said. "So I know this season will be very tough with the pressure and with everything else."
Up next for the lefthanded Czech will be Russian Nina Bratchikova, who beat France's Claire Feuerstein 3-6, 6-3, 7-5 on Day 5.
A seventh-seeded Li pushed her French Open winning streak to nine matches with a 52-minute 6-0, 6-2 dismantling of Frenchwoman Stephanie Foretz Gacon.
The Chinese Li, who became the first-ever Asian Grand Slam champion by running the table here a year ago, will meet American Christina McHale in her next outing.
Ninth-seeded former world No. 1 Caroline Wozniacki of Denmark handled Aussie Jarmila Gajdosova 6-1, 6-4, while 10th-seeded rapidly-rising German Angelique Kerber whipped Belarusian Olga Govortsova 6-3, 6-2, and 14th-seeded Francesca Schiavone overcame Bulgarian Tsvetana Pironkova 2-6, 6-3, 6-1 in just over two hours. The former U.S. Open runner-up Wozniacki will tangle with tough Estonian Kaia Kanepi on Saturday, while the Italian Schiavone will lock horns with surprise American Varvara Lepchenko in her next outing.
Schiavone was the surprise French Open champ in 2010 and last year's Roland Garros runner-up to Li.
Czech veteran Klara Zakopalova took down 16th-seeded Russian glamour girl Maria Kirilenko 6-4, 3-6, 6-3; the Uzbekistan native Lepchenko toppled 19th-seeded former world No. 1 Jelena Jankovic of Serbia 7-6 (7-4), 4-6, 6-4; 22nd-seeded Anastasia Pavlyuchenkova of Russia beat Melinda Czink of Hungary 4-6, 6-3, 6-3; a 23rd-seeded Kanepi drilled Romanian Irina-Camelia Begu 6-4, 6-1; 25th-seeded German Julia Goerges grounded Brit Heather Watson 6-3, 6-4; and 28th-seeded Chinese Peng Shuai defeated Spaniard Lourdes Dominguez Lino 6-4, 6-3. The fading former U.S. Open runner-up Jankovic is a three-time French Open semifinalist.
Additional second-round wins came for McHale, Dutchwoman Arantxa Rus, Kazakhstan's Yaroslava Shvedova, and Spaniard Carla Suarez Navarro. Rus topped giant-killer Virginie Razzano in straight sets, while the 20-year-old McHale whipped fellow American, 18-year-old Lauren Davis, 6-1, 6-3. The French Razzano shocked former No. 1 and pre-tournament favorite Serena Williams in a three-set thriller here on Tuesday.
A match between a second-seeded Sharapova and Japan's Ayumi Morita was pushed into Friday. Sharapova was scheduled to play on Court Chatrier, but a marathon men's match between American John Isner and Frenchman Paul-Henri Mathieu prevented that from happening.
The three-time major champion Sharapova needs a French Open title to complete a career Grand Slam.
The third round will get underway Friday, including matches for top seed Victoria Azarenka, third seed Agnieszka Radwanska and sixth-seeded U.S. Open champ and 2010 French Open runner-up Sam Stosur. Azarenka will take on Canadian Aleksandra Wozniak, while Radwanska will face 26th-seeded former French Open champ Svetlana Kuznetsova, and Stosur will be opposed by 27th- seeded Russian slugger Nadia Petrova.
Azarenka beat Sharapova in this year's Aussie Open final to capture her first- ever Grand Slam title and become the No. 1 player in the world.
Also on the Day-6 schedule are Kerber, 13th-seeded former Roland Garros champ Ana Ivanovic and rising American Sloane Stephens.
