Serena advances to Toronto quarterfinals

TORONTO, Aug. 20 (UPI) -- Second-seeded Serena Williams advanced to the quarterfinals Thursday with a 6-1, 6-4 third-round win over Alona Bondarenko at the Rogers Cup in Toronto.

The reigning Wimbledon, Australian Open and U.S. Open champion made quick work of her Ukrainian opponent, avoiding the fate of older sister, Venus, a 1-6, 7-5, 6-4 loser to Kateryna Bondarenko, Alona's sister, in Tuesday's second round.

"I couldn't get my serve in and got frustrated (in the second set)," a somewhat disappointed Serena Williams told the Toronto Star. "I have to get to the final. I have to get there myself."

Also advancing Thursday were No. 4 Elena Dementieva, No. 14 Agnieszka Radwanska, Samantha Stosur, Lucie Safarova, a 7-6 (7-3), 6-4 winner over China's Jie Zheng; and Alisa Kleybanova, who knocked off top-seeded Dinara Safina on Wednesday.
