40 Years...40 Champions For two wondrous weeks each summer, the US Open showcases the sport of tennis and its greatest players. Day and night, through seven rounds of play, only the best of the best survive. In fact, only 40 players in the 40 years of Open tennis have raised the US Open singles championship trophy. Billie. Chrissie. Jimbo. McEnroe. Martina. Pete. Andre. Serena. Venus. They've become household names in countless households. But that's what happens when you have the world's toughest tennis being played before worldwide fans at the game's greatest show. A test not only of talent but of will, an annual drama spotlighting not just athletic achievement but head and heart, the US Open--America's Grand Slam--is where the stars or tennis really earn their stripes.
