BEIJING (AP) — Second-seeded Victoria Azarenka reached the third round of the China Open by beating Polona Hercog of Slovakia 7-6 (8), 6-3 Wednesday.

The fourth-ranked Belarussian will next face Anastasia Pavlyuchenkova of Russia. Pavlyuchenkova beat Azarenka in doubles on Wednesday.

"I just need to get some rest and get ready tomorrow," Azarenka said.

In the third round, Ana Ivanovic defeated third-seeded Vera Zvonareva 6-2, 6-1.

The former No. 1 said changes made by new coach Nigel Sears were starting to pay off, especially in improving her serve and forehand.

"Sometimes it takes time to see results, but it's coming together now," said Ivanovic, the 2008 French Open champion.

Ivanovic will next meet 11th-seeded Agnieszka Radwanska of Poland, who beat Zheng Jie of China 6-1, 6-4.

In the men's tournament, Ivan Ljubicic of Croatia beat Florian Mayer of Germany 6-0, 2-6, 6-3, Fernando Verdasco of Spain defeated Flavio Cipolla of Italy 2-6, 6-1, 6-2 and Mikhail Youzhny of Russia beat Feliciano Lopez of Spain 6-7 (5), 6-2, 7-5.
