Rosewall and Pancho Gonzáles as well as Andrés Gimeno, Roy Emerson, and Fred Stolle. In 1971, the WCT circuit grew to 21 tournaments around the globe. In July 1971, at its annual meeting, the International Lawn Tennis Federation (ILTF) voted to ban all WCT contract professionals from the ILTF tournaments and facilities from the beginning of 1972 onwards. At the end of the 1971 WCT season, the top eight players from the season were seeded according to their WCT rankings and played a year-end championship tournament in November. This was held about two weeks before the similar championship of the rival Grand Prix circuit, called The Masters. For commercial reasons, from 1972 onward this championship, played on indoor carpet, was usually held in the spring in Dallas, Texas and became known as the WCT Finals. The tournament ran for 19 years and the last championship was held in 1989. The format for this event was adopted by the Association of Tennis Professionals for the year-end Tour Finals. In April 1972 an agreement was reached between the ILTF and WCT that divided the 1973 tour in a WCT circuit that ran from January through May and a Grand Prix circuit that was scheduled for the rest of the year. Under this agreement WCT players were again allowed to play the Grand Prix tournaments. The WCT tour was merged into the Grand Prix tennis circuit in 1978. On 30 April 1981 WCT announced its withdrawal from the Grand Prix circuit and the establishment of its own full calendar season for 1982. According to Lamar Hunt the reasons for the withdrawal were the restrictions placed on them by the Men's Professional Council, the administrators of the Grand Prix circuit. In January 1983, WCT sued the Men's International Professional Tennis Council (MIPTC), the Association of Tennis Professionals and the ITF, claiming unfair restriction of trade. In November 1983 a settlement resulted in WCT's reincorporation into the Grand Prix with effect from 1985. 1989 was the last season of WCT. The ATP established its own tennis circuit from 1990. On August 28, 1990, after the Tournament of Champions event at Forest Hills, WCT announced its dissolution. WCT also built and operated tennis clubs in the United States; WCT Lakeway World of Tennis in Lakeway (metro Austin), Texas and WCT Peachtree World of Tennis in Peachtree Corners (metro Atlanta), Georgia.
