US Open

Getting to every ball, putting most shots right where she wanted them, Kim Clijsters was so dominant in the U.S. Open final that it would have taken a perfect performance to top her. Vera Zvonareva did not produce one. Far from it.

Top-seeded Caroline Wozniacki stretched her winning streak to 13 matches by beating 45th-ranked Dominika Cibulkova of Slovakia 6-2, 7-5 in the US Open quarterfinals today.

Stanislas Wawrinka beat Sam Querrey in five sets to put two Swiss men in a Grand Slam quarterfinals for the first time in the Open era - and keep the Americans out of the US Open quarters for the second straight year.

Forehands, backhands, big serves. Caroline Wozniacki got almost everything back today, frustrating Maria Sharapova in a 6-3, 6-4 victory to advance to the quarterfinals of the US Open.

Roger Federer is one cool customer.

Victoria Azarenka collapsed and fell to the ground while chasing down a routine forehand and had to be taken off the court in a wheelchair half an hour into her match on another steamy day at the US Open.
