Guillermo Vilas

Short Biography

Guillermo Vilas (born 17 August 1952, in Buenos Aires, Argentina) is a retired professional tennis player from Argentina who won four major singles titles. Known for his prolific match play, especially on clay, he became the second man to win more than 900 matches in the Open Era, and his 660 wins on clay are by far the most of the era. His peak was the 1977 season during which he won two major titles (both on clay), had two long match win streaks of 46 all-surface and 53 on clay, and finished with an Open Era record 134 match wins. He also popularized the between-the-legs tweener shot, also known as the "Gran Willy" in his honor.
