The WCT Finals was a tennis tournament that served as the season-ending championship for the World Championship Tennis circuit. From 1971-1989, the event was held annually in Texas on indoor carpet courts, . The 1971 quarterfinals and semifinals were played in Houston, and final played at Moody Coliseum in Dallas. The 1972-1979 editions were played at Moody Coliseum, and the 1980-1989 tournaments at Reunion Arena in Dallas. The WCT, in 1974, was the first tennis tournament to experiment with electronic line calling.
The first edition of the WCT Finals in 1971 was played in November, just a few days before The Masters, the equivalent of the WCT Finals for the rival Grand Prix circuit. Because of TV pressure, the second edition was held in May 1972 and most of the following editions were organized in between months of March and May.
In 1972 another edition, less important and with half the prize money, was held in November in Rome. The prize money offered to the winner, Arthur Ashe, was US$25,000 compared to the US$50,000 won by Ken Rosewall for the main edition in May. A decade later there were three editions of the WCT Finals; the most important one in Dallas, and the others in autumn in Naples, Italy, and in winter (in January 1983) in Detroit. John McEnroe was the most successful player winning a record five titles out of eight final appearances.
