NEW YORK (AP) -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.
