Williams sisters are beatable: Mauresmo

The Williams sisters can be beaten and the return of Lindsay Davenport could help break up their domination of the women's game, a confident Amelie Mauresmo said before the start of the U.S. Open on Monday.

After winning the Canadian Open and pushing Davenport hard in a close-fought duel at the New Haven Open last week, the Frenchwoman said she was in good form going into the U.S. Open, where she is seeded 10th.

"I feel my tennis is picking up form, I'm reaching an excellent level," Mauresmo, a semi-finalist at Wimbledon this year, said in an interview in Le Figaro newspaper.

Serena Williams has already won the French Open and Wimbledon this year and is the top seed at the U.S. Open, with her elder sister Venus, champion for the last two years, seeded second. Serena took the U.S. title in 1999.

Mauresmo believes other players are ready to break the sisters' domination of the game. "This domination won't go on forever. Everyone has highs and lows. They are on top... but it won't take a lot to change that," she said. "The Williamses are very strong but beatable."

Davenport, who has made a strong comeback after returning from knee surgery in January, could be a threat with her powerful play, she said.

Mauresmo said she had taken a few days rest after losing to Davenport last week, so as to be fresh for the U.S. Open.

"I want things to go well here," she said.
