Which male tennis players have won on all surfaces?

Answer 1

Although Jimmy Connors never won the French Open, his victory at the 1976 US Open came during the brief period (1975-77) when that tournament was held on clay courts. Connors is, therefore, one of only five men (Mats Wilander, Andre Agassi, Roger Federer and Rafael Nadal are the others) to have won a Grand Slam singles title on grass courts, hard courts, and clay courts. Connors also won the U.S. Open singles championship itself on on grass courts, hard courts, and clay courts, the only man to accomplish that trio of wins.
