BEIJING, Oct. 1 (UPI) -- Local favorite Li Na dropped just one game Tuesday in posting a second-round win at the China Open tennis tournament in Beijing.

World No. 1 Serena Williams also advanced in straight sets but in a much more difficult match, beating Francesca Schiavone 6-4, 7-5 in 1 hour, 47 minutes. Williams notched the only break of the first set but needed three breaks in the second as Schiavone was 2-of-7 in break chances in the set.
No. 6-seeded Carolina Wozniacki came out a 6-3, 6-1 winner over Monica Niculescu as she had six breaks in Niculescu's eight games serving and Angelique Kerber, seeded seventh, raced past Laura Robson 6-1, 6-2.
