Schnyder mixes up game to score second-round win in Stanford

"I guess I've really made the most of my opportunity getting in -- a bit of luck, find some form," Stosur said. "I served pretty good. I hit a few double faults but also a few aces. I attacked when I could and played pretty good defense when I needed to."

Earlier, Keothavong forced Bartoli to hit a lot of balls in order to win.

"From one double break down it was almost the end for me. I decided I was going to win this match whatever it takes," said Bartoli, who got more aggressive and came to the net for quick points. "She was playing so well from the baseline and was hardly missing one ball. ... I was able to do it. It was hard to do it, but I was able to get those winners."

The 29-year-old Schnyder is making her sixth appearance at Stanford, with a runner-up performance in 2006 here to Kim Clijsters as her best showing. She hasn't dropped a set in her first two matches.

Schnyder led 5-3 in the first-set tiebreaker against Kleybanova before the 19-year-old Russian fought back to make it interesting. The left-handed Schnyder trailed 3-2 in the second set after Kleybanova held serve, but evened it at 3-3 after winning her serve at love and hitting an ace on game point. Kleybanova then beat herself with her shaky serve. She double-faulted on back-to-back points to fall behind 4-3, Schnyder then held serve at love again to make it 5-3. After consecutive aces to start her next service game, Kleybanova had another double fault before holding that game.

"At the end I really felt comfortable on my service games," said Schnyder, who hit several pretty drop shots. "I felt like I finally had better speed and footwork on my forehands."

This was the players' second career meeting and second this year after Schnyder won 6-1, 6-3 in first round of the Gold Coast event in Australia.
