PATTAYA, Thailand (AP)—Top-seeded Vera Zvonareva of Russia advanced to the Pattaya Open quarterfinals with a 6-3, 6-2 victory Thursday over Alberta Brianti of Italy.
The defending champion wasn't challenged by the 72nd-ranked Brianti. The 14th-rankled Russian stuck to a baseline game, winning crucial points throughout the match.
The win set up a match against Sybille Bammer, who won the title in 2007. Bammer fought back from a set down to beat teenager Chan Kai-Chen 5-7, 6-4, 6-2.
Many seeded players went out early. The latest was third-seeded Vera Dushevina of Russia, who lost to Ekaterina Bychkova 6-4, 6-1. Bychkova posted her first win over the 40th-ranked Dushevina after losing three previous matches.
She will play Sesil Karatantcheva in the quarterfinal Friday.
``I've never played her before in the pro circuit, but we used to compete in the juniors. But we will surely fight hard for the semifinal,'' Bychkova said.
