NEW YORK -- American teenager Melanie Oudin's surprising run at the U.S. Open has ended with a 6-2, 6-2 quarterfinal loss to No. 9-seeded Caroline Wozniacki of Denmark.
The 70th-ranked Oudin, a 17-year-old player from Marietta, Ga., lost 14 of the first 18 points Wednesday night, and never recovered.
Oudin had upset four higher-ranked players including three-time major champion Maria Sharapova and Beijing Olympic gold medalist Elena Dementieva to become the youngest quarterfinalist at Flushing Meadows since Serena Williams in 1999.
And Oudin's last three victories each came after dropping the first set.
But Wozniacki, who leads the women's tour in match victories this season, stopped that pattern to reach her first Grand Slam semifinal.
