US Open:Sharapova out,Federer advances.

Five-time US Open champion Roger Federer beat 13th-seeded Jurgen Melzer of Austria 6-3, 7-6 (4), 6-3 on Monday night to reach the quarterfinals at a 26th consecutive Grand Slam tournament and set up an intriguing rematch with Robin Soderling. No. 5 Soderling of Sweden is the man who ended Federer's streak of 23 consecutive Grand Slam semifinals with an upset in this year's French Open quarterfinals. Meanwhile, Maria Sharapova lost to No. 1-seeded Caroline Wozniacki of Denmark in the fourth round 6-3, 6-4. It's the first victory for Wozniacki in three career meetings against Sharapova, but they hadn't met since 2008. In that time, the 20-year-old Wozniacki has grown as a player and built a huge supply of confidence, thanks to her Grand Slam final debut in New York and, most recently, her 18-1 record since Wimbledon. Wozniacki carries a 12-match winning streak into her quarterfinal against 45th-ranked Dominika Cibulkova, who eliminated 2004 U.S. Open champion Svetlana Kuznetsova 7-5, 7-6 (4)..
