Melanie Oudin's magical US Open is over. Showing signs of shakiness in her first Grand Slam quarterfinal, the 17-year-old American got off to a slow start tonight against No. 9-seeded Caroline Wozniacki of Denmark and never really recovered, losing 6-2, 6-2.
Oudin, who is ranked 70th, upset four more established 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. (More Melanie Oudin stories.)
