"I took things seriously right from the start," Mauresmo said. "I focused on my game, on what I needed to do today. I played at a good level, while preventing her from developing her game,'' she added.

The second-ranked Mauresmo broke Dushevina three times in the first set with her heavy topspin. The Frenchwoman's powerful groundstrokes continued in the second to win in 1 hour.

Dechy, ranked 20th, pressured Dementieva's serve in the first set, breaking her in the second and sixth games for a 4-2 lead.

At 5-3, Dechy missed an easy volley and drop shot, and Dementieva broke back on a backhand the Frenchwoman sent into the net.Both players then held serve to force a tiebreaker.

In another second-round match, Schnyder got the better of Pironkova in baseline exchanges with her powerful forehand.

She converted three of seven break points in the first set, but needed to wait until the ninth game in the second to break again.

Third-seeded Nadia Petrova of Russia also advanced to the quarterfinals with a 6-4, 6-1 victory over Anna Smashnova of Israel.

Smashnova had trouble with her serve, dropping the second game on a double fault.

Petrova held her serve in the third game for a 3-0 lead, but couldn't convert break points in the next game, allowing Smashnova to rally.

Smashnova broke back in the seventh game on a string of unforced errors by her Russian opponent, and went level at 4-4. But a wide backhand by Smashnova at 5-4 and 30-40 helped Petrova win a tight first set in 55 minutes.
