Vera Zvonareva moved a win away from her second Grand Slam final of 2010 on Wednesday, defeating Kaia Kanepi 6-3, 7-5 at the U.S. Open.

The Russian won the quarterfinal match by getting balls back and watching her 31st-seeded opponent self-destruct. Estonian Kanepi, a quarterfinalist at Wimbledon this year, made 60 unforced errors in a windy Arthur Ashe Stadium.

"In these conditions, the most important thing is to find the right balance," Zvonareva said. "It's between keeping the ball in

play and going for your shots, and I think I was able to find that balance."

Zvonareva, who lost to Serena Williams in the Wimbledon final this year, will play the winner of the day's later quarterfinal between No. 1 Caroline Wozniacki and unseeded Dominika Cibulkova.

Kanepi and Zvonareva combined for a total of 88 unforced errors and only 28 winners on Wednesday.

The tone for the match was set early, when the players traded service breaks right away to make it 1-1 and combined for 12

unforced errors and one winner through the first two games.

"It was tough for both of us," Zvonareva said. "We tried to show our best today and sometimes we had some ridiculous rallies."

Other matches scheduled for Wednesday were men's quarterfinals between No. 17 Gael Monfils and No. 3 Novak Djokovic and a night contest between No. 2 Roger Federer and No. 5 Robin Soderling.

The first women's semifinal was set up on Tuesday, when a pair of two-time winners at Flushing Meadows, No. 2 Kim Clijsters and No. 3 Venus Williams, each won.
