Pete Sampras

Pete Sampras dominated the 1990s with 14 Grand Slam titles and a massive serve-and-volley game that made him virtually unbeatable on grass courts. He won Wimbledon 7 times, the most of any male player until Roger Federer, and held the world No. 1 ranking for 286 weeks. His ability to rise to the occasion in the biggest moments defined an era of American tennis.
