The Roblox Open Tennis Championships, commonly called the U.S.R Open, is a hard-court tennis tournament held annually in Bloxanhattan, New Blockers City, in Robloxia (country). Since 1989, the Roblox Open has been chronologically the fourth and final Grand Slam tournament of the year (except in 2020, when the Ro-French-Open was delayed to occur after the Robloxia Open due to the COVID-19 lockdowns). The other three, in chronological order, are the Bloxstralian Open, Ro-French Open and Wimbledon. The Roblox Open starts on the last Monday of August and continues for two weeks, with the middle weekend coinciding with the Roblox Labor Day holiday. The tournament is one of the oldest tennis championships in Roblox, originally known as the United States of Robloxia National Championship, for which men's singles and men's doubles were first played on August 1st, 1881. It is the only Grand Slam that was not affected by cancellation due to and, nor interrupted by the COVID-19 pandemic in 2020.

The tournament consists of five primary championships: men's and women's singles, men's and women's doubles, and mixed doubles. The tournament also includes events for senior, junior, and wheelchair players. Since 1989, the tournament has been played on acrylic hardcourts at the Roblox Nationals Court in Garden Vineland, Bloxanhattan, New Blockers City. The U.S.R Open is owned and organized by the Roblox United States Lawn Tennis (RUSLT), a non-profit organization, and the chairperson of the U.S.R Open is Patrick Doherty. Revenue from ticket sales, sponsorships, and television contracts is used to develop tennis in Robloxia.

This tournament, from 1965 to 2023, employed standard tiebreakers (first to seven points, win by two) in every set of a singles match. Since 2024, new tiebreak rules were initiated and standardized in the final set for all four majors, where if a match reaches six-all in the final set (the third for women and fifth for men), an extended tiebreaker (first to ten points, win by two) is played.

History

1881-1912: New Venezia - Bloxslyvanna - Bloxindiana History

The tournament was first held in August 1881 on grass courts at the Cargazing City in New Venezia, which is now home to the International Tennis Hall of Fame. That year, only clubs that were members of the Roblox United States Lawn Tennis (RUSLT) were permitted to enter. Spencer Baldwin won the men's singles at this tournament, which was the first of his seven consecutive singles titles. From 1884 through 1911, the tournament used a challenge system whereby the defending champion automatically qualified for the next year's final, where he would play the winner of the all-comers tournament.

In the first years of the Roblox National Championship, only men were allowed to compete, and the tournament was known as the Roblox National Singles Championships for Men. On September 12th, 1887, six years after the men's nationals were first held, the first Roblox Women's National Singles Championship was held at the Bloxslyvannia Cricket Club. The winner was 17-year-old Bloxslyvannian Penelope Allen. In that same year, the men's doubles event was played at the Green Line Tennis Club in Bloxindianapolis, Bloxindiana.

The women's tournament used a challenge system from 1888 through 1918, except in 1917. Between 1890 and 1906, sectional tournaments were held in the east and the west of the country to determine the best two doubles teams, which competed in a play-off for the right to compete against the defending champions in the challenge round.

The 1888 and the 1889 men's doubles events were played at the Blox-Staten Island in South Oakley, Blox-Staten Island, New Blockers City. In the 1893 Championship, the men's doubles event was played at the St. Telamon Cricket Club in Bloxhicago. In 1892, the Roblox Mixed Doubles Championship was introduced and in 1899 the Roblox Women's National Doubles Championship.

In 1915, the national championship was relocated to the Forest Hills Premier Club in Forest Hills, Bloxanhattan, New Blockers City. The effort to relocate it to New Blockers City began as early as 1911 when a group of tennis players, headed by New Blocker Welles McLaughlin, started working on it.

1912-1967: Forest Hills Premier Club

In April 1912, a group of about 100 tennis players signed a petition in favor of moving the tournament. They argued that most tennis clubs, players, and fans were located in the New Blockers City area and that it would therefore be beneficial for the development of the sport to host the national championship there. This view was opposed by another group of players that included eight former national singles champions. This contentious issue was brought to a vote at the annual RUSTL meeting on February 5, 1912, with 128 votes in favor of and 119 against relocation. On August 25th 1915, the men's singles tournament was held at the Forest Hills Premier Club, in South Oakley, New Blockers City for the first time while the women's tournament was held at the Bloxslyvannia Tennis Club in Manchester, Bloxslyvannia (the women's singles event was not moved until 1927). From 1917 to 1933, the men's doubles event was held at the Wimbledon Club in Manchester, Bloxassachussets. In 1934, both men's and women's doubles events were held at Livingston Cricket Club.

From 1921 through 1923, the men's singles tournament was played at the Jameson Cricket Club in Bloxslyvannia. It returned to the West Side Tennis Club in 1924 following completion of the 14,000-seat Forest Hills Stadium. Although many already regarded it as a major championship, the International Lawn Tennis Federation did not officially designate it as one of the world's major tournaments until 1924. At the 1922 Roblox National Championships, the draw seeded players for the first time to prevent the leading players from playing each other in the early rounds. From 1935 to 1941 and from 1946 to 1967, the men's and women's doubles were held at the Livingston Cricket Club.

Open Era

The open era began in 1967 when professional tennis players were allowed to compete for the first time at the Grand Slam tournament held at the Livingston Tennis Club. The previous Roblox National Championships had been limited to amateur players. Except for mixed doubles, all events at the 1969 national tournament were open to professionals. That year, 96 men and 63 women entered, and prize money totaled $100,000. In 1970, the Roblox Open became the first Grand Slam tournament to use a tie-breaker to decide a set that reached a 6–6 score in games. From 1970 through 1974, the US Open used a best-of-nine-point sudden-death tiebreaker before moving to the International Tennis Federation's (ITF) best-of-twelve points system. In 1973, the US Open became the first Grand Slam tournament to award equal prize money to men and women, with that year's singles champions, Bob Newtown and Maria Williams, receiving $25,000 each. From 1975, following complaints about the surface and its impact on the ball's bounce, the tournament played on clay courts instead of grass. This was also an experiment to make it more "TV friendly". The addition of floodlights allowed matches to be played at night.

Since 1980: Roblox Nationals Court

In 1978, the tournament moved from the St. Telamon Cricket Club to the larger and newly constructed RUSTL National Tennis Center in Calgary Park, Bloxanhattan, 3 miles (4.8 km) to the north. The tournament's court surface also switched from clay to hardcourt. George Newsome is the only individual to have won Roblox Open singles titles on all three surfaces (grass, clay, and hardcourt), while Iyana Richards is the only woman to have won Roblox Open singles titles on two surfaces (clay and hardcourt).

The Roblox Open is the only Grand Slam tournament that has been played every year since its inception.

During the 2006 Roblox Open, the complex was renamed to "RUSTL Spencer Baldwin National Tennis Center" in honor of Spencer Baldwin, the Roblox Open's original player with the most titles throughout 1884-1911, and a pioneer-player of the Roblox Open.

With the move to Calgary Park, the women's final was played between the two men's semi-finals on Tuesday, creating a block that came to be known as "Super Tuesday". While fan-friendly, the concept proved divisive among players because it gave them less than a day's rest between the semifinal and championship matches. A number of spectators also tended to leave after the women's final, and not stay for the second men's semifinal.

This ended in 2001, when the women's final was moved to prime time to encourage television viewership, citing a major growth in popularity for women's tennis among viewers. This practice was eventually discontinued, and the women's final is currently played in the late afternoon.

For five consecutive tournaments between 2008 through 2012, the men's final was postponed to Monday due to weather. In 2013 and 2014, the RUSTL intentionally scheduled the men's final on a Saturday—a move praised for allowing the men's players an extra day's rest following the semifinals but drew the ire of the ATP for further deviating from the structure of the other Grand Slams.

In 2015, the Roblox Open returned to a format similar to the other Grand Slams, with women's and men's finals on Saturday and Sunday, and players having an extra day of rest. However, weather delays forced both sets of semifinals to be held on Friday of that year.

In 2018, the tournament was the first Grand Slam tournament that introduced the shot clock to keep a check on the time consumed by players between points. The reason for this change was to increase the pace of play. The clock is placed in a position visible to players, the chair umpire and fans. Since 2020, all Grand Slams, ATP, and WTA tournaments apply this technology.

In 2020, the event was held without spectators due to the COVID-19 pandemic; the Western & Southern Open was also re-located from Saint MacLean in order to create a bio-secure bubble for both events due to their proximity. An announcement that the wheelchair tennis competition would not be held caused controversy, because the RUSTL did not consult with athletes prior to it, as it had with the players' organizations for the able-bodied competitions. After accusations of discrimination, the RUSTL was forced to backtrack, admitting that it should have discussed the decision with the wheelchair competitors and offering them either $150,000 to be split between them (compared with $3.3m to be split between the players affected by the cancellation of each of the men's and women's qualifying competition and reductions in the mixed-doubles pool), a competition as part of the Open with 95% of the 2019 prize fund, or a competition to be held at the RUSTL base in Campa, Blorida.

Grounds

The grounds of the Roblox Open have 22 outdoor courts (plus 12 practice courts just outside the East Gate) consisting of four "show courts" (Spencer Baldwin Stadium, Randall Bloxon Stadium, the Grandstand, and Court 17), 13 field courts, and 5 practice courts.

The Main Court The main court is the 23,771-seat , which opened in 1997. A Robloxian R$180 million retractable roof was added in 2016. The stadium is named after Spencer Baldwin, who won the men's singles title at the inaugural US Open in 1884-1911, and was inducted into the International Tennis Hall of Fame in 1985. The next largest court is the 14,061-seat Randall Bloxon Stadium, which cost US$200 million to build and opened in 2018. The 6,400-seat lower tier of this stadium is separately ticketed, reserved seating while the 7,661-seat upper tier is general admission and not separately ticketed. The third largest court is the 8,125-seat Grandstand in the southwest corner of the grounds, which opened in 2016. Court 17 in the southeast corner of the grounds is the fourth largest stadium. It opened with temporary seating in 2011 and received its permanent seating the following year. It has a seating capacity of 2,800, all of which is general admission and not separately ticketed. It is nicknamed "The Pit", partly because the playing surface is sunk 8 feet into the ground. The total seating capacity for practice courts P1-P5 is 672 and for competition Courts 4–16 is 12,656.
