Guillermo Vilas

Guillermo Vilas is an Argentine former professional tennis player. Vilas was the world No. 1 of the Grand Prix seasons in 1974, 1975 and 1977. He won four major titles, the year-end championships, and 78 career singles titles overall, 62 of which were ATP titles. World Tennis, Agence France-Presse and Livre d'or du tennis 1977, among other rankings and publications, rated him as world No. 1 in 1977. In the computerized ATP rankings, he peaked at No. 2 in April 1975, a position he held for a total of 83 weeks, although some have argued that Vilas should have been ranked No. 1 for at least 10 weeks, particularly in 1977 when he won 2 majors. He was inducted into the International Tennis Hall of Fame in 1991, two years after his first retirement.
