Grand Slam (tennis)
The Grand Slam in tennis is the achievement of winning all four major championships in one discipline in a calendar year. In doubles, a Grand Slam may be achieved as a team or as an individual with different partners. Winning all four major championships consecutively but not within the same calendar year is referred to as a "non-calendar-year Grand Slam", while winning the four majors at any point during the course of a career is known as a "Career Grand Slam".
The term Grand Slam is also attributed to the Grand Slam tournaments, referred to as Majors, and they are the world's four most important annual professional tennis tournaments. They offer the most ranking points, prize money, public and media attention, the greatest strength and size of the field and, in recent years, the longest matches for men.
The tournaments are overseen by the International Tennis Federation, rather than the separate men's and women's tour organizing bodies, the Association of Tennis Professionals and Women's Tennis Association, but both the ATP and WTA award ranking points based on players' performances in them.
The Grand Slam tournaments are the Australian Open in January, the French Open from late May to early June, Wimbledon in late June to early July, and the US Open in late August to early September, with each played over two weeks. The Australian and the US tournaments are played on hard courts, the French on clay court, and Wimbledon on grass court. Wimbledon is the oldest tournament, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905, but it was not until 1923 that all four were designated as "Official Championships".
History
With the growing popularity of tennis, and with the hopes of unifying the sport's rules internationally, the British and French tennis associations started discussions at their Davis Cup tie, and in October 1912 organized a meeting in Paris, joined by the Australasian, Austrian, Belgian, Spanish, and Swiss associations. They subsequently formed the International Lawn Tennis Federation, holding their first meeting in 1913, joined by the Danish, German, Dutch, Russian, South African, and Swedish organizations. Voting rights were divided based on the perceived importance of the individual countries, with Great Britain's Lawn Tennis Association receiving the maximum six votes. Three tournaments were established, being designated as "World Championships":- World Grass Court Championships, played on grass courts.
- World Hard Court Championships, played on clay courts.
- World Covered Court Championships, played on an indoor wood surface.
The United States National Lawn Tennis Association expressed disagreement over the power distribution within the ILTF and the designation of "World Championship" status to the British and French tournaments, and thus initially refused to join the Federation, choosing instead to be bystanders to their meetings. By the 1920s, with the World Covered Court Championships failing to attract top players and the growing success of American and Australian tennis, the ILTF worked to convince the USNLTA to join them, meeting their demand to drop the designation of "World Championships" from all three tournaments in March 1923, which led to the demise of both the World Covered Court Championships and the World Hard Court Championships. A new category of "Official Championships" was created for the national championships of Britain, France, Australia, and the US. By the 1930s, these four tournaments had become well defined as the most prestigious in the sport.
In 1933, Jack Crawford won the Australian, French, and Wimbledon Championships, leaving him just needing to win the last major event of the year, the U.S. Championships, to become the reigning champion of all four major tournaments, a feat described as "a grand slam" by sports columnist Alan J. Gould of The Reading Eagle, and later that year by John Kieran of The New York Times, who stated that if Crawford won at Forest Hills it "would be something like scoring a grand slam on the courts, doubled and vulnerable." The term 'Grand Slam' originates from the card game contract bridge, where it is used for winning all possible tricks. In golf it was used for the first time to describe a total of four wins, specifically Bobby Jones' achievement of winning the four major golf tournaments of the era, which he accomplished in 1930. "Grand Slam" or "Slam" has since also become used to refer to the tournaments individually. The first player to win all four majors in a calendar year and thus complete a Grand Slam was Don Budge in 1938.
At the time, only amateur players were allowed to participate in the Grand Slam and other ILTF-sanctioned tournaments. Amateur standing, regulated by the ILTF alongside its associated national federations, forbade players from receiving prize money, earning pay by teaching tennis, being contracted by promoters and playing paid exhibition matches, though expense payments were allowed along with certain monies from sporting goods companies or other benefactors. Amateurs who "defected" to become professional were banned from competing in amateur tournaments and dropped from their national associations. The first major professional tour was established in 1926 by promoter C. C. Pyle with a troupe of American and French players, most notably Suzanne Lenglen, playing exhibition matches to paying audiences.
Over the next decades many other head-to-head tours were run and professional tournaments established, with three, the U.S. Pro Tennis Championships, French Pro Championship and Wembley Championships, standing out, and considered to have been the professional majors. By the 1950s, largely due to efforts of player/promoter Jack Kramer, this lucrative parallel circuit was luring in most of the star amateurs on the men's side, much to the ire of the ILTF and organizers of the Grand Slam tournaments. It was an open secret that the top players who remained as amateurs were receiving undeclared under-the-table payments from tournament promoters, an arrangement tolerated by their national tennis associations to dissuade them from joining the pro ranks and secure their availability for the majors and Davis Cup. This system was derisively referred to as 'shamateurism' that was seen as undermining the integrity of the sport. Ramanathan Krishnan and Roy Emerson, for example declined large contract offers from the professional promoters, with the latter stating that he was better paid in the amateur circuit.
Tensions over this status quo, which had been building for decades, finally came to a head in 1967. The first tournament open to professional tennis players played on Centre Court at Wimbledon, the Wimbledon Pro, was staged by the All England Lawn Tennis Club in August, offering a prize fund of US$45,000. The tournament was deemed very successful, with packed crowds and the play seen as being of higher quality than the amateur-only Wimbledon final held two weeks earlier. This success in combination with large signings of top players to two new professional tours—World Championship Tennis and the National Tennis League—convinced the LTA on the need for open tennis. After a British proposal for this at the annual ILTF meeting was voted down, the LTA revolted, and in its own annual meeting in December it voted overwhelmingly to admit players of all statuses to the 1968 Wimbledon Championships and other future tournaments in Britain, "come hell or high water". The eventual backing of the USNLTA that came after a February 1968 vote forced the ILTF to yield and allow each nation to determine its own legislation regarding amateur and professional players, which it voted for in a special meeting in March 1968. This marked the start of the Open Era of tennis, with its first tournament, the 1968 British Hard Court Championships, beginning three weeks later on 22 April in Bournemouth, England, while the first open Grand Slam tournament, the 1968 French Open, was held in May.
Even after the advent of the Open Era, players including John McEnroe and Chris Evert have pointed out that skipping the Australian Open was the norm because of the travelling distance involved and the inconvenient dates close to Christmas and New Year. There were also the contracted professional players who had to skip some major events like the French Open in the 1970s because they were committed to the more profitable pro circuits. In one case, Australian players including Rod Laver, Ken Rosewall and Roy Emerson who had contracts with George MacCall's National Tennis League were prevented from participating in the 1970 Australian Open because the financial guarantees were deemed insufficient.
Although it has been possible to complete a Grand Slam in most years and most disciplines since 1925, it was not possible from 1940 to 1945 because of interruptions at Wimbledon, the Australian and French Championships due to World War II, the years from 1970 to 1985 when there was no Australian tournament in mixed doubles, 1986 when there was no Australian Open, and 2020 when Wimbledon was cancelled due to the COVID-19 pandemic.
