Grand Slam (tennis)
Winning all four major tennis championships in one calendar year.
In tennis, a Grand Slam is the feat of winning all four major championships in a single discipline within one calendar year. For doubles, this can be accomplished either by a fixed team or by an individual playing with different partners. If a player wins all four majors consecutively but across two calendar years, it is called a "non-calendar-year Grand Slam." Winning all four majors at any time during a career is known as a "Career Grand Slam."
The term "Grand Slam" also refers to the four tournaments themselves, often called the Majors. These are the world’s four most important annual professional tennis events, offering the highest ranking points, prize money, public and media attention, the strongest and largest fields, and, for men, the longest matches (best of five sets, while women play best of three). The tournaments are overseen by World Tennis, not by the separate men’s and women’s tour bodies (the ATP and WTA), though both the ATP and WTA award ranking points based on players’ results in them.
The Grand Slam tournaments are the Australian Open in January, the French Open from late May to early June, Wimbledon from late June to early July, and the US Open from late August to early September. Each lasts two weeks. The Australian and US Opens are played on hard courts, the French on clay, and Wimbledon on grass. Wimbledon is the oldest, founded in 1877, followed by the US Open in 1881, the French in 1891 (becoming a major in 1925), and the Australian in 1905. However, it was not until 1923 that all four were officially designated as "Official Championships."
**History**
As tennis grew in popularity, the British and French tennis associations began discussions during their Davis Cup tie, and in October 1912 organized a meeting in Paris. They were joined by the Australasian, Austrian, Belgian, Spanish, and Swiss associations. This led to the formation of the International Lawn Tennis Federation (ILTF), which held its first meeting in 1913, with the Danish, German, Dutch, Russian, South African, and Swedish organizations also joining. Voting rights were allocated based on each country’s perceived importance, with Great Britain’s Lawn Tennis Association (LTA) receiving the maximum six votes. Three tournaments were established and designated as "World Championships": the World Grass Court Championships (on grass), the World Hard Court Championships (on clay), and the World Covered Court Championships (on indoor wood). The LTA was given the perpetual right to organize the World Grass Court Championships at Wimbledon, and France was allowed to stage the World Hard Court Championships until 1916. In 1913, New Zealander Anthony Wilding won all three World Championships.
The United States National Lawn Tennis Association (USNLTA) disagreed with the ILTF’s power distribution and the "World Championship" status given to the British and French tournaments, so it initially refused to join, remaining a bystander. By the 1920s, the World Covered Court Championships failed to attract top players, and American and Australian tennis grew in success. The ILTF worked to convince the USNLTA to join, meeting its demand to drop the "World Championships" designation from all three tournaments in March 1923. This led to the end of both the World Covered Court and World Hard Court Championships. A new category, "Official Championships," was created for the national championships of Britain, France, Australia, and the United States. By the 1930s, these four tournaments were firmly established as the sport’s most prestigious.
In 1933, Jack Crawford won the Australian, French, and Wimbledon Championships, needing only the U.S. Championships to hold all four major titles. Sports columnist Alan J. Gould of *The Reading Eagle* described this potential feat as "a grand slam," and later that year John Kieran of *The New York Times* wrote 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" comes from the card game contract bridge, where it means winning all possible tricks. In golf, it was first used to describe Bobby Jones’ 1930 achievement of winning the four major tournaments of that era. "Grand Slam" or "Slam" has since also been used to refer to the tournaments themselves. The first player to win all four majors in a calendar year, completing a true Grand Slam, was Don Budge in 1938.
At that time, only amateur players could compete in the Grand Slam and other ILTF-sanctioned tournaments. Amateur status, regulated by the ILTF and its national federations, forbade players from receiving prize money, earning pay by teaching tennis, being contracted by promoters, or playing paid exhibition matches. However, expense payments and certain monies from sporting goods companies or benefactors were allowed. Amateurs who "defected" to become professionals were banned from amateur tournaments and dropped from their national associations. The first major professional tour was established in 1926 by promoter C. C. Pyle, featuring a troupe of American and French players—most notably Suzanne Lenglen—who played exhibition matches for paying audiences. Over the following decades, many head-to-head tours and professional tournaments were created, including the U.S. Pro Tennis Championships, the French Pro Championship, and the Wembley Championship.

Lore & Background
The four Grand Slam tournaments—the Australian Open, French Open, Wimbledon, and US Open—are the world’s most important annual professional tennis events, offering the highest ranking points, prize money, public and media attention, and the strongest fields. Each tournament is played over two weeks, with men’s matches best of five sets and women’s best of three. The Australian and US Opens are contested on hard courts, the French Open on clay, and Wimbledon on grass. Wimbledon is the oldest, founded in 1877, followed by the US Open (1881), the French Open (1891, attaining major status in 1925), and the Australian Open (1905). However, all four were not officially designated as “Official Championships” until 1923. This designation emerged after the International Lawn Tennis Federation (ILTF), formed in 1913, abandoned its earlier “World Championships” system—which had included grass, hard court, and indoor wood surface titles—following disagreements with the United States. The four national championships of Britain, France, Australia, and the US were then elevated. The term “Grand Slam” itself was first applied to tennis in 1933 by sports columnist Alan J. Gould, referencing the card game contract bridge, after Jack Crawford won three majors and needed the US title. Don Budge became the first player to win all four in a single calendar year in 1938. A Grand Slam is the achievement of winning all four majors in one discipline within a calendar year; a non-calendar-year Grand Slam means winning them consecutively across two years, while a Career Grand Slam is winning each major at any point in a career. In doubles, a Grand Slam can be achieved as a team or individually with different partners. The tournaments are overseen by World Tennis, not the separate ATP and WTA tours, though both tours award ranking points based on performances in them.

Did You Know?
- The term 'Grand Slam' originates from the card game contract bridge, where it is used for winning all possible tricks.
- The Grand Slam tournaments are independently organized by their respective national tennis associations and sanctioned by the ITF, not by a governing body called 'World Tennis'.
Vision & Founding
Michael Johnson had been nurturing the concept of a professional track and field league since the 1990s. The stated mission was to elevate track and field beyond the four-year Olympic rhythm, creating a recurring league format that would keep the sport in the public eye year-round. Johnson and billionaire hedge fund manager Bill Ackman were reported to be personally funding the venture with millions of their own capital. The design called for four meets spread across the track season, with global athletes competing in a structure modeled after other professional sports leagues. The league aimed to replace the sporadic, Olympics-dependent visibility of the sport with a consistent, recurring calendar that treated track and field as a year-round spectacle rather than a quadrennial event.
Athlete Roster & Early Momentum
The league attracted significant attention when it confirmed its early signings. However, the absence of prominent names like Noah Lyles and Sha'Carri Richardson drew attention.
Financial Collapse & Bankruptcy
The league's financial troubles became apparent almost immediately after its inaugural season. Notable competitors including Gabby Thomas, Emmanuel Wanyonyi, Alison dos Santos, and Grant Fisher publicly noted they had not yet been compensated. World Athletics head Sebastian Coe confirmed the governing body was monitoring the situation. In a July 24 interview, Johnson acknowledged the league was in a difficult financial situation partly due to excessive spending, and revealed that a key investor had pulled an eight-figure commitment right after the Kingston Slam. A scheduled $3 million payment in late July went unpaid. By late November, the league offered creditors a 50% settlement to avoid bankruptcy.
Competition Format & Structure
The league's competitive architecture was designed to create sustained engagement across a season rather than a single weekend. Each season comprised four slams held between April and June, with the original plan extending through September. Every slam featured six event categories for men and women, each category encompassing two disciplines contested over a weekend. The field in each category consisted of eight athletes: four Grand Slam Racers selected from world rankings who appeared consistently across all four meets, and four Grand Slam Challengers who were emerging athletes vying for a Racer spot the following year. Points were allocated from 12 down to 1 for first through eighth place in each individual event, with the category winner determined by the combined score across both disciplines. In case of a tie, the highest placement in either event would break it.
Frequently Asked Questions
What does a Grand Slam mean in tennis?
A Grand Slam in tennis refers to a player or team winning all four major championships—the Australian Open, French Open, Wimbledon, and US Open—within a single calendar year. It is the most prestigious seasonal accomplishment in the sport.
How is a Grand Slam different from a Career Grand Slam?
A Grand Slam requires all four major titles to be won within one calendar year, whereas a Career Grand Slam simply means a player has won each of the four majors at some point during their career, regardless of the years involved. There is also a non-calendar-year Grand Slam, where the four titles come in consecutive order but span two calendar years.
Can a doubles team achieve a Grand Slam in tennis?
Yes, a Grand Slam in doubles can be earned either by the same partnership winning all four majors in one year or by an individual player completing the set with different partners across the four events. This flexibility makes the doubles Grand Slam slightly broader in definition than the singles version.
