Major professional tennis tournaments before the Open Era
The oldest of these three Professional Majors , or "Pro Slams", was the U.S. Pro Tennis Championships, played at a variety of different venues and on a variety of different surfaces, between 1927 and 1999. Between 1954 and 1962, the US Pro was played indoors in Cleveland and was called the World Professional Championships. The most prestigious of the three was generally the Wembley Championship. Played between 1934 and 1990, at the Wembley Arena in England, it was unofficially usually considered the world's championship until 1967. The third professional major was the French Pro Championship, played between 1934 and 1968, on the clay-courts of Roland Garros, apart from 1963–1967, when it was played on the indoor wood courts of Stade Coubertin.
