Wozniacki out of US Open

Slowed by a right knee injury, eighth-seeded Caroline Wozniacki

failed to make it out of the first round of her second straight

Grand Slam tournament, falling 6-2, 6-2 to 96th-ranked

Irina-Camelia Begu of Romania at the U.S. Open on Tuesday.

Wozniacki quit after the first set of her semifinal match last

Friday in New Haven. Four days later, she was ousted from the U.S.

Open, finishing the match with tape that trainers applied to her

hurting knee during an injury timeout in the second set.

Begu got her first U.S. Open win.

Wozniacki was the top seed at Flushing Meadows the last two

years but fell in the semifinals both times.

Earlier this summer at Wimbledon, she lost her first-round match

to Tamira Paszek.
