1. Roland Garros
The Roland Garros Tournament, also known as the French Open, is one of the four Grand Slam tennis events held annually. It takes place in late May to early June in Paris, France, and is named after the famous French aviator Roland Garros. This prestigious tournament is played on the world’s largest clay court. Similar to other Grand Slam tournaments like the Australian Open and Wimbledon, the French Open follows a 5-set match format (for men’s singles) and a 3-set match format (for women’s singles), with no tie-breaker in the final set (except for the US Open). The event also includes men’s, women’s, and mixed doubles competitions. Roland Garros is widely regarded as the most physically demanding Grand Slam. The current defending champion is Novak Djokovic, who has won the title twice.
The tournament was first held in 1891 under the name Championat de France International de Tennis (French International Tennis Championship). Initially, only French male players or foreign players affiliated with a French tennis club were allowed to compete. In 1897, the women’s tournament was introduced, and it wasn’t until 1924 that foreign players were invited to join. In 1927, the French team stunned the tennis world by winning the Davis Cup in the United States. Following this victory, France was granted the privilege of hosting the next year’s Davis Cup, and to prepare for the 1928 tournament, the French government decided to build a tennis stadium at Porte d'Auteuil, funded by a donation of three hectares from the Stade de France club. The stadium was named after Roland Garros, the French World War I aviator, and the tournament has carried his name ever since.


2. ATP World Tour Finals
The ATP World Tour Finals, officially known as the ATP Finals, is the final men’s tennis tournament of the year, featuring the top 8 players in the world. Unlike most other tennis tournaments, the ATP Finals doesn’t follow a traditional knockout format. The 8 players are divided into two groups, each containing 4 players, and compete in a round-robin format within their group. The top 2 players from each group progress to the semifinals, with the winners meeting in the final to determine the champion. The tournament, which began in 1970, is considered a major milestone in tennis history. Initially known as The Masters, it was organized by the International Tennis Federation (ITF) and was a year-end event for the top male players. The results of this tournament did not contribute to the players’ overall season rankings. In 1990, the ATP took over the management of men’s tennis, replacing The Masters with the ATP Tour World Championship, where results began counting toward the players’ season rankings. The champion earned points equivalent to winning a Grand Slam. The ITF continued to organize the Grand Slam events and introduced the Grand Slam Cup, gathering the top 16 players based on Grand Slam performance.
In December 1999, the ATP and ITF agreed to merge their efforts, creating a combined event called the Tennis Masters Cup. Similar to the previous tournaments, the Masters Cup featured the top 8 players, based on the ATP Race rankings. However, players ranked 8th were not guaranteed entry. If a player outside the top 8 won a Grand Slam during the year and was ranked within the top 20, they would earn a spot in the event. In 2009, the event was renamed the ATP World Tour Finals and has been held at the O2 Arena in London from 2009 to 2012. Recently, the doubles competition has also been held alongside the singles, with the top 8 doubles teams also competing in a round-robin format leading to semifinals and finals. Roger Federer, a former world No. 1, leads the event with 6 titles, followed by Pete Sampras and Ivan Lendl with 5 each.


3. Wimbledon
Wimbledon is the oldest and most prestigious tennis tournament in the world. Held at the All England Club in Wimbledon, London, since 1877, it is one of the four Grand Slam tournaments alongside the Australian Open, Roland Garros, and the US Open. Since the Australian Open switched to hard courts in 1988, Wimbledon remains the only major event played on grass courts. The tournament takes place over two weeks in late June and early July, with the finals for both men's and women's singles held on the second Saturday and Sunday of July. The tournament features five adult events, alongside youth competitions and special invitation categories. Wimbledon is well-known for its strict dress code, as players are required to wear all white, and for its tradition of not having advertising around the courts. In 2009, the Centre Court was fitted with a retractable roof, allowing play to continue during rain delays.
In the men’s singles and doubles, the first player to win three sets is declared the winner, while in other events, two sets are required to win. If the score reaches 6-6 in any set, a tiebreaker is played. Since 2019, if the final set reaches 12-12, a tiebreaker is used to decide the match. All events are played in a knockout format, except for the mixed doubles and senior categories, which are also played in a knockout format. Before 1922, the defending champion (except in women’s doubles and mixed doubles) was automatically placed in the final, giving them an advantage by resting while their competitors had to play through the earlier rounds. Since 1922, defending champions are required to play through all rounds like other competitors.


4. US Open
The US Open is one of the four major tennis Grand Slam events held annually. It takes place in late August and early September in New York City, USA, making it the final Grand Slam of the year. Before 1968, it was known as the U.S. National Championships and was only open to amateur players. However, in 1968, the tournament expanded to include professional players, and its name was changed to the US Open. From 1881 to 1915, it was held at the Newport Casino in Newport, Rhode Island, before moving to the West Side Tennis Club in Forest Hills, New York, in 1915. It has been held at its current location in Flushing Meadows, New York, since 1978. Over the years, the US Open has been played on three different surfaces: grass (1881-1974), clay (1975-1977), and hard courts (1978-present). Jimmy Connors is the only player to have won on all three surfaces, winning on grass in 1974, on clay in 1976, and on hard courts in 1978, 1982, and 1983.
Today, the entire tennis complex in Flushing Meadows is known as the USTA Billie Jean King National Tennis Center, named after the former world number one female tennis player Billie Jean King. It features several courts, including the main Arthur Ashe Stadium with a seating capacity of 24,000. This stadium is named in honor of Arthur Ashe, the first African-American player to win the US Open in 1968. Other notable courts include Louis Armstrong Stadium (Court 2) and the Grandstand Stadium (Court 3). Smaller courts like Courts 4, 7, and 11 seat 1,000 spectators each. All US Open courts are made of DecoTurf hard courts, a surface made of multiple layers of rubber mixed with sand and applied to concrete. This surface allows for a fast and consistent bounce, ideal for players with powerful serves and aggressive net play. Since 2005, the courts have been changed from the traditional green to blue for better ball visibility.


5. Australian Open
The Australian Open is one of the four major tennis Grand Slam events, held annually in Melbourne, Australia. It marks the first Grand Slam of the year and takes place in the latter half of January. Organized by Tennis Australia, the event was first held in 1905 as the Australasian Championships, later becoming the Australian Championships in 1927, and then the Australian Open in 1969. The tournament is traditionally played as best-of-five sets for men’s singles and best-of-three sets for women’s singles, without a tiebreak in the final set. Alongside singles events, doubles and mixed doubles competitions are also held. Initially, the event was played at various venues across Australia, including Melbourne (46 times), Sydney (17 times), and Adelaide (14 times), before moving to Melbourne Park in 1988 to accommodate growing attendance. The event has also been hosted in New Zealand twice, in 1906 and 1912. Over time, the Australian Open became more accessible, especially with the advent of air travel for international players. In 1972, it was decided that the tournament would be held exclusively in Melbourne each year, with the Kooyong Lawn Tennis Club as the venue until the shift to Melbourne Park.
Melbourne Park, formerly known as Flinders Park, was built in 1988 to replace the Kooyong Club, which had become too small for the expanding event. The move to Melbourne Park brought a significant increase in audience numbers, with attendance rising by 90%, from 140,000 in 1987 to 266,436 in 1988. The early years of the tournament were marked by the challenges posed by Australia's vast distances, which made it difficult for international players to attend. For example, it took 45 days by sea to travel from Europe to Australia in the 1920s. The first overseas players to attend the tournament arrived by air in 1946, with the US Davis Cup team. Travel was equally challenging for Australian players, with long journeys across the country. When the event was held in Perth, players from Victoria or New South Wales were hesitant to travel the 3,000 kilometers by train to participate, and in 1906, only two Australian players competed in Christchurch, New Zealand.
