American players prove dominant in U.S. Open series
The last several years have been marked by a lack of American success in the world of men's tennis. In recent years, only two Grand Slam titles have been won by Americans. Andre Agassi won the 2003 Australian Open and Andy Roddick won the 2003 U.S. Open. In addition, only one American -- Roddick -- has remained in the upper tier with players like Lleyton Hewitt, Marat Safin and Roger Federer, who hail from Australia, Russia and Switzerland, respectively.
