The Russian, champion in 2002 and 2004, now stands 11-0 at the tropical resort venue, where she earned her first title a week after lifting the US Open two years ago.

Kuznetsova, the world No. 5, will face American Lindsay Davenport on Saturday in a battle of former Grand Slam champions.

Davenport, the defending champion and former world No. 1, defeated Hana Sromova 6-1, 6-0 in a match where the Czech's unorthodox, no-rhythm game caused her little concern.

"We had some long points and I was working them," said the three-time Grand Slam champion, who will be happy to get some serious competition in the form of Kuznetsova.

"I was able to overpower her. She has no rhythm of pace, but I can't really complain about winning an easy match.

"I felt all the time that I had the match on my racket. At least in the next round I'll be able to rip some balls again."

Kuznetsova said she is keen to take on Davenport after losing three of four to the Californian, the last time in the Australian Open fourth round.

"It will be a high-level match. She's playing well even if she's had a long break (before the US Open) due to injury.

"The key to her game is her serve. If I can move her around and get to the net, I think I have my chances."

Kuznetsova said that a test against a top player is exactly what she wants at the semi-final stage. "She's one of the best in the world, it will be a pleasure to play her."

Swiss second seed Patty Schnyder had another easy outing, defeating Melinda Czink 6-2, 6-2.

Sixth seed Marion Bartoli kept France in the title race with her defeat of Russian Olga Poutchkova 6-2, 6-4.
