Serena, Li reach third round in China

Beijing, China ( - Serena Williams and Li Na were among Tuesday's second-round winners, while Venus Williams was sent packing at the $5 million China Open.

The top-seeded Serena, who has already clinched the year-end No. 1 ranking, beat wild card and former French Open champion Francesca Schiavone of Italy by a 6-4, 7-5 margin, while the fourth-seeded heavy Chinese favorite Li blitzed Bojana Jovanovski of Serbia 6-0, 6-1.

Serena won this event in 2004 and is playing for the first time since capturing the U.S. Open earlier this month for her 17th career Grand Slam singles championship. She is gunning for her 10th title of 2013 and Tuesday's win gave the American great a stellar match record of 78-4 for the year.

Li lost to Serena in the semifinals at Flushing Meadows. She won a season-opening event in Shenzhen, China, but has not had much success at this event in her home country with semifinal losses in 2010 and 2012 her best results in eight previous appearances.

Next up for Li will be Germany's Sabine Lisicki, the Wimbledon runner-up who cruised past wild card and former No. 1 Venus Williams 6-1, 6-2. The 13th- seeded Lisicki fired seven aces past Venus in their brief 53-minute affair.

Sixth-seeded former world No. 1 Caroline Wozniacki of Denmark recorded a 6-3, 6-1 victory over Monica Niculescu of Romania.

The 2010 Beijing titlist Wozniacki will next do battle with 11th-seeded American Sloane Stephens, who outlasted qualifier Eugenie Bouchard of Canada 6-1, 1-6, 6-4.

German Angelique Kerber, the No. 7 seed, beat Brit Laura Robson 6-1, 6-2 to set up a third-round match with 10th-seeded Italian Roberta Vinci, who rallied past Chinese wild card Zhang Shuai 3-6, 6-3, 6-1.

Other wins from seeded players came from No. 9 seed Petra Kvitova and 12th- seeded Carla Suarez Navarro. The Czech slugger Kvitova got past American Varvara Lepchenko 2-6, 6-2, 6-0, while and Suarez Navarro beat American qualifier Lauren Davis 6-4, 6-2. The former Wimbledon champion Kvitova is fresh off her title in Tokyo, where she topped the German Kerber in an all- left-handed final.

Additionally, Russian Maria Kirilenko, the 2005 Beijing champ, discarded Pole Urszula Radwanska 6-4, 6-4. Kirilenko should have her hands full with the U.S. and French Open champion Serena on Thursday.
