# Guillermo Vilas

Guillermo Vilas (Spanish pronunciation:; born 17 August 1952) is an Argentine former professional tennis player. He was the world No. 1 of the Grand Prix seasons in 1974, 1975 and 1977. He won 62 singles titles and 16 doubles titles during his career, four major titles and the 1974 Tour Finalss. World Tennis, Agence France-Presse and Livre d'or du tennis 1977 (Christian Collin-Bernard Ficot), 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 two majors. He was inducted into the International Tennis Hall of Fame in 1991, two years after his first retirement.
Vilas is known for his prowess on clay courts. He won over 650 matches on clay, an all-time record. His peak was the 1977 season during which he won 16 ATP singles titles, including two majors (both on clay) and had a 53-match winning streak on clay, the longest in the Open Era at his time. In 2016, The Daily Telegraph ranked him as the third best male clay-court player of all time, behind Rafael Nadal and Björn Borg. In 2018, Steve Tignor for Tennis Magazine ranked him as the 16th greatest tennis player of the Open Era.
Historical and statistical studies presented in 2015 by Argentinian journalist Eduardo Puppo and Romanian mathematician Marian Ciulpan concluded that Vilas should have been No. 1 in the old ATP ranking system for seven weeks between 1975 and 1976. The ATP and its chief executive at that time, Chris Kermode, although not refuting the data, decided not to officially recognize Vilas as No. 1. In October 2020, Netflix released a documentary film about Vilas's case titled Guillermo Vilas: Settling the Score. In May 2024, ATP's vice-president confirmed that Vilas will never be number one.

## Career

Raised in the seaside resort of Mar del Plata, Vilas was a left-hander and played his first tour event in 1968. He was in the year-ending top ten from 1974 through 1982. He was a clay-court specialist and played well on hard-court, grass, and carpet surfaces.
He won four Grand Slam titles: the 1977 French Open and the 1977 US Open (both played on clay) and the 1978 and 1979 Australian Open (both played on grass). He was also the runner-up at the French Open three times (1975, 1978, and 1982) and at the Australian Open once (January 1977).
In 1974, he won the year-end Masters Grand Prix title. In addition, he won seven Grand Prix Super Series titles (1975–80), the precursors to the current Masters 1000.

### Best year

A left-handed baseliner, Vilas's best year on tour was 1977 when he won 16 singles titles, including two of the four major Grand Slam singles tournaments and 16 of the 31 Association of Tennis Professionals tournaments he entered. His playing record for 1977 was 130 wins against 15 losses (89.65%). Not including the Masters year-end championship, he won 72 of his last 73 ATP matches in 1977. The highest point during this run was winning the last US Open played at Forest Hills against Jimmy Connors 2–6, 6–3, 7–6$^{(7–4)}$, 6–0 in a match where Vilas surprised his American rival by attacking the net.

### Winning streak

In 1977 he won seven consecutive titles after Wimbledon—Kitzbühel (clay), Washington (clay), Louisville (clay), South Orange (clay), Columbus (clay), US Open (clay) and Paris (clay)—and set up a 46-match all-surface winning streak. He also had a record 53-match winning streak on clay courts, which stood until surpassed by Rafael Nadal in 2006. Both his winning streaks were terminated in October 1977 by Ilie Năstase in the final of the Raquette d'Or tournament. In that best-of-five-set final, Vilas dropped the first two sets by 6–1, 7–5 and then retired in protest of Năstase's use of a spaghetti racquet. (The ITF had voted to ban the racquet, but the ban did not take effect until the day after the match). After that he won a further 28 matches in a row with titles at Tehran, Bogotá, Santiago, Buenos Aires (all on clay), and Johannesburg (hard). That run was ended in the Masters semi-finals by Björn Borg.

### ATP ranking No. 1 controversy

Even though he won 21 singles titles including 16 ATP titles that season, including the French Open and the US Open and was the runner-up at the January edition of the Australian Open in 1977, Vilas was never ranked by the ATP as world No. 1 during 1977 which was due to the fact that the rankings at the time were based on the average of a player's results. He was instead ranked year-end world No. 2, behind Jimmy Connors who won 8 singles titles only (including the Masters Grand Prix and did not win any of the 4 Grand Slam titles, but was the runner-up at Wimbledon and the US Open in 1977). Nevertheless, Vilas was rated number one by World Tennis, France Presse, Tennis de France, Le Livre d'or du Tennis, Gene Scott, Peter Bodo, Christian Quidet, and Michael Sutter. The International Tennis Hall of Fame inscription for Vilas stated "it was generally considered Vilas was the real No. 1 for 1977". Vilas was also rated number one by Bud Collins and John Barrett by the 2010s.
Argentine journalist Eduardo Puppo and Romanian mathematician Marian Ciulpan investigated the 1973–78 period records, and delivered a detailed report with more than 1,200 pages in which they came to the conclusion that Vilas should have been ranked No. 1 for five weeks in 1975 as well as during the first two weeks of 1976 and handed over their research to the ATP at the end of 2014. Although the study was not refuted, in May 2015 the ATP announced it had decided not to make official the No. 1 position for Vilas because it happened in the interval between the publications of the official rankings.
In October 2020, Netflix released a documentary about the controversy titled Guillermo Vilas: Settling the Score. It also covered (briefly) Evonne Goolagong's recognition as world no. 1 (for two weeks in 1976) retroactively by the WTA in 2007.
In May 2024, ATP's vice-president confirmed that Vilas will never be number one.

### Other controversies

In 1983, the Men's International Professional Tennis Council on June 7 suspended Vilas for one year and fined him $20,000, having found that his manager and coach, Ion Tiriac, on the player's behalf, had accepted about $60,000 in appearance money from tournament promoters. Such payments were barred by the rules of the Grand Prix circuit.
In 2005, after living the life of an international playboy most of his life, Vilas settled down and married. He was 47 when he met Phiangphathu Khumueang, a 17-year-old from Thailand, and they married five years later.

### Retirement

Vilas retired from the ATP Tour in 1989 but still played on the ATP Challenger Series until 1992. He was inducted into the International Tennis Hall of Fame in 1991. Vilas was in the stands at Flushing Meadows to cheer on his countryman, Juan Martín del Potro, who beat Roger Federer in an upset in the 2009 US Open final.

## Family

Vilas married Phiangphathu Khumueang from Thailand in 2005. They have three daughters and one son. They reside in Monaco. He is reportedly suffering from a form of dementia.
