Guillermo Vilas

Guillermo Vilas was a left-hander with heavy topspin on both sides and extraordinary fitness, who could stay in rallies for as long as it took. In 1977 he won the French Open and the US Open, which was then played on clay at Forest Hills, and put together a 46-match winning streak. He won more than 60 tour titles, most of them on clay, and helped make Argentina a clay-court nation.
