US Open (tennis)#Boys' Singles

In early 1915, 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 York City area and that it would therefore be beneficial for the development of the sport to host the national championships there.{{cite news |url=https://timesmachine.nytimes.com/timesmachine/1915/01/17/301768272.pdf |title=Newport May Lose Tennis Tourney |newspaper=The New York Times |date=January 17, 1915 |access-date=July 16, 2012 |archive-url=https://web.archive.org/web/20210729141902/https://timesmachine.nytimes.com/timesmachine/1915/01/17/301768272.pdf |archive-date=July 29, 2021 |url-status=live}} This view was opposed by another group of players that included eight former national singles champions.{{cite news |url=https://timesmachine.nytimes.com/timesmachine/1915/01/18/100131498.pdf |title=Want Newport for Tennis Tourney |newspaper=The New York Times |date=January 18, 1915 |access-date=July 16, 2012 |archive-url=https://web.archive.org/web/20210729141630/https://timesmachine.nytimes.com/timesmachine/1915/01/18/100131498.pdf |archive-date=July 29, 2021 |url-status=live}}{{cite news |url=https://timesmachine.nytimes.com/timesmachine/1915/01/23/100134451.pdf |title=A Tennis "Solar Plexus" |newspaper=The New York Times |date=January 23, 1915 |access-date=July 16, 2012 |archive-url=https://web.archive.org/web/20210729141729/https://timesmachine.nytimes.com/timesmachine/1915/01/23/100134451.pdf |archive-date=July 29, 2021 |url-status=live}} This contentious issue was brought to a vote at the annual USNLTA meeting on February 5, 1915, with 128 votes in favor of and 119 against relocation.{{cite news |url=https://news.google.com/newspapers?id=vw0nAAAAIBAJ&dq=national%20lawn%20tennis%20newport%20new%20york&pg=5776%2C1049672 |title=Tourney Goes to New York |newspaper=Boston Evening Transcript |date=February 6, 1915 |access-date=July 16, 2012 |archive-date=August 17, 2021 |archive-url=https://web.archive.org/web/20210817142634/https://news.google.com/newspapers?id=vw0nAAAAIBAJ&dq=national%20lawn%20tennis%20newport%20new%20york&pg=5776,1049672 |url-status=live }}{{cite news |url=https://timesmachine.nytimes.com/timesmachine/1915/02/07/104641023.pdf |title='All-Comers' Tourney to be Restricted |newspaper=The New York Times |date=February 7, 1915 |access-date=July 16, 2012 |archive-url=https://web.archive.org/web/20210729142253/https://timesmachine.nytimes.com/timesmachine/1915/02/07/104641023.pdf |archive-date=July 29, 2021 |url-status=live}}{{cite news |url=https://timesmachine.nytimes.com/timesmachine/1915/02/06/106729791.pdf |title=Newport Loses Tennis Tourney |newspaper=The New York Times |date=February 6, 1915 |access-date=July 21, 2012 |archive-url=https://web.archive.org/web/20210729141644/https://timesmachine.nytimes.com/timesmachine/1915/02/06/106729791.pdf |archive-date=July 29, 2021 |url-status=live}} In August 1915, the men's singles tournament was held at the West Side Tennis Club, Forest Hills in New York City for the first time, while the women's tournament was held at the Philadelphia Cricket Club in Chestnut Hill, Philadelphia (the women's singles event was not moved until 1921).

The Open Era began in 1968 when professional tennis players were allowed to compete for the first time at the Grand Slam tournament held at the West Side Tennis Club. The previous U.S. National Championships had been limited to amateur players. Except for mixed doubles,{{citation needed|date=August 2018}} all events at the 1968 national tournament were open to professionals. That year, 96 men and 63 women entered, and prize money totaled $100,000. In 1970, the US Open became the first Grand Slam tournament to use a tiebreaker 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, John Newcombe and Margaret Court, receiving $25,000 each. Beginning in 1975, following complaints about the surface and its impact on the ball's bounce, the tournament was 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.{{Cite web |title=U.S. Open History |url=https://www.tennis.com/tournaments/2012/08/us-open-history/16931/ |website=Tennis.com |access-date=May 15, 2020 |archive-date=October 20, 2021 |archive-url=https://web.archive.org/web/20211020122209/https://www.tennis.com/error/404.html |url-status=live }}{{Cite web |title=When the US Open was played on clay… |url=https://thelacesout.com/when-the-us-open-was-played-on-clay-acbd0247aa6c |last=Maverick |first=Vickey |date=August 27, 2016 |website=Medium |access-date=May 15, 2020 |archive-date=April 15, 2021 |archive-url=https://web.archive.org/web/20210415230042/https://thelacesout.com/when-the-us-open-was-played-on-clay-acbd0247aa6c?gi=ae060c1a841c |url-status=live }}

In 1978, the tournament moved from the West Side Tennis Club to the larger and newly constructed USTA National Tennis Center in Flushing Meadows, Queens, {{convert|3|mi|km|1}} to the north. The tournament's court surface also switched from clay to hardcourt. Jimmy Connors is the only individual to have won US Open singles titles on all three surfaces (grass, clay, and hardcourt), while Chris Evert is the only woman to have won US Open singles titles on two surfaces (clay and hardcourt).

The US Open is the only Grand Slam tournament that has been played every year since its inception.{{cite web |url=http://www.itftennis.com/about/grand-slams/us-open.aspx |title=Grand Slams – US Open |publisher=International Tennis Federation |access-date=August 23, 2012 |archive-date=March 27, 2012 |archive-url=https://web.archive.org/web/20120327103128/http://www.itftennis.com/about/grand-slams/us-open.aspx |url-status=live }}

In 2005 the US Open added Wheelchair singles and Wheelchair doubles tournament, while in 2006 the US Open added the Quad singles and Quad doubles tournament. During the 2006 US Open, the complex was renamed to "USTA Billie Jean King National Tennis Center" in honor of Billie Jean King, a four-time US Open singles champion and one of women's tennis's early pioneers.{{cite news |url=https://www.nytimes.com/2006/08/03/sports/tennis/03tennis.html |title=Tennis Center to Be Named for Billie Jean King |author=Richard Sandomir |newspaper=The New York Times |date=August 3, 2006 |access-date=February 20, 2017 |archive-date=September 7, 2021 |archive-url=https://web.archive.org/web/20210907031328/https://www.nytimes.com/2006/08/03/sports/tennis/03tennis.html |url-status=live }}

With the move to Flushing, the women's final was played between the two men's semi-finals on Saturday, creating a block that came to be known as "Super Saturday". 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.{{cite web |url=https://www.espn.com/tennis/usopen15/story/_/id/13550899/tennis-traditional-us-open-scheduling-favors-roger-federer |title=Traditional US Open scheduling favors Federer |website=ESPN.go.com |date=August 31, 2015 |access-date=August 31, 2015 |archive-date=February 16, 2016 |archive-url=https://web.archive.org/web/20160216212549/http://espn.go.com/tennis/usopen15/story/_/id/13550899/tennis-traditional-us-open-scheduling-favors-roger-federer |url-status=live }}

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.{{cite news |url=https://nypost.com/2001/08/30/ladies-first-womens-open-final-is-so-hot-theyre-moving-it-to-prime-time/ |title=Ladies first – women's open final is so hot, they're moving it to prime-time |newspaper=New York Post |access-date=September 12, 2016 |archive-date=August 13, 2020 |archive-url=https://web.archive.org/web/20200813123059/https://nypost.com/2001/08/30/ladies-first-womens-open-final-is-so-hot-theyre-moving-it-to-prime-time/ |url-status=live }} 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 USTA intentionally scheduled the men's final on a Monday—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.{{cite web |title=US Open schedules Monday finish |url=http://en.espn.co.uk/tennis/sport/story/183876.html |website=ESPN.co.uk |access-date=August 31, 2015 |archive-date=March 5, 2021 |archive-url=https://web.archive.org/web/20210305014044/https://en.espn.co.uk/tennis/sport/story/183876.html |url-status=live }}{{cite web |url=http://www.espn.co.uk/espn/sport/story/184271.html |title=ATP blasts US Open over Monday final |website=ESPN.co.uk |access-date=August 31, 2015 |archive-date=March 6, 2020 |archive-url=https://web.archive.org/web/20200306091206/http://en.espn.co.uk/espn/sport/story/184271.html |url-status=live }}

In 2015, the US 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.{{cite magazine |url=https://www.si.com/tennis/2015/09/11/us-open-schedule-watch-semifinal-matches |title=U.S. Open schedule: How to watch semifinal matches |magazine=Sports Illustrated |access-date=September 12, 2015 |archive-date=October 29, 2020 |archive-url=https://web.archive.org/web/20201029165740/https://www.si.com/tennis/2015/09/11/us-open-schedule-watch-semifinal-matches |url-status=live }}

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.{{efn|name=Shot Clock|Once the chair umpire has announced the score following the previous point, the countdown starts and players have 25 seconds to begin their service motion. However, the chair umpire has the ability and discretion to pause or reset the clock to 25 seconds the clock if a point with a particularly long rally merits a pause for the players to recover their breath. In normal circumstances during the game, if the player has not started the service motion at the completion of the 25-second countdown, the chair umpire issues a time violation. The server will receive a warning and for each subsequent violation, the player loses a first serve (second serves are supposed to happen without delay, so the clock won't be used). In the case of the receiver, if it isn't ready at the end of 25 seconds, the chair umpire first issues a warning, then the loss of a point with every other violation. After even-numbered games, the chair umpire will start the clock when the balls are all in place on the server's end of the court.{{cite news |title=US Open '18: On the clock! 25-second countdown's Slam debut |date=August 26, 2018 |url=https://eu.usatoday.com/story/sports/tennis/2018/08/25/us-open-18-on-the-clock-25-second-countdowns-slam-debut/37603593/ |agency=AP |access-date=March 29, 2020 |archive-date=November 9, 2020 |archive-url=https://web.archive.org/web/20201109034735/https://eu.usatoday.com/story/sports/tennis/2018/08/25/us-open-18-on-the-clock-25-second-countdowns-slam-debut/37603593/ |url-status=live }}}} The reason for this change was to increase the pace of play.{{cite web |url=https://www.usopen.org/en_US/news/articles/2018-07-10/50_for_50_billie_jean_king_1971_1972_and_1974_womens_singles_champion.html |title=Shot clock, warm-up clock to be implemented at 2018 US Open |last=Marshall |first=Ashley |date=July 11, 2018 |website=usopen.org |access-date=March 29, 2020 |archive-date=October 27, 2020 |archive-url=https://web.archive.org/web/20201027011751/https://www.usopen.org/en_US/news/articles/2018-07-10/50_for_50_billie_jean_king_1971_1972_and_1974_womens_singles_champion.html |url-status=live }} The clock is placed in a position visible to players, the chair umpire and fans.{{cite web |url=https://www.atptour.com/en/news/shot-clock-implemented-in-us-summer-swing-2018 |title=USTA, ATP & WTA Implement Rules Innovations At Events Throughout Summer |date=July 11, 2018 |website=atptour.com |access-date=March 29, 2020 |archive-date=October 2, 2021 |archive-url=https://web.archive.org/web/20211002211506/https://www.atptour.com/en/news/shot-clock-implemented-in-us-summer-swing-2018 |url-status=live }} Since 2020, all Grand Slams, ATP, and WTA tournaments apply this technology.{{cite news |title=Tennis: ATP to use Shot Clock in all tournaments in 2020 |date=March 13, 2019 |url=https://www.reuters.com/article/us-tennis-atp/tennis-atp-to-use-shot-clock-in-all-tournaments-in-2020-idUSKCN1QU2H0 |work=Reuters |location=London |access-date=March 29, 2020 |archive-date=November 8, 2020 |archive-url=https://web.archive.org/web/20201108002531/https://www.reuters.com/article/us-tennis-atp/tennis-atp-to-use-shot-clock-in-all-tournaments-in-2020-idUSKCN1QU2H0 |url-status=live }}

All the courts used by the US Open are illuminated, allowing matches and television coverage to extend into the evening.

From 1978 to 2019, the US Open was played on a hardcourt surface called Pro DecoTurf. It is a multi-layer cushioned surface and classified by the International Tennis Federation as medium-fast.{{cite web |url=http://www.itftennis.com/technical/courts/classified-surfaces/about-court-pace-classification.aspx |title=About Court Pace Classification |publisher=International Tennis Federation |access-date=August 25, 2018 |archive-date=January 21, 2021 |archive-url=https://web.archive.org/web/20210121212202/https://www.itftennis.com/technical/courts/classified-surfaces/about-court-pace-classification.aspx |url-status=live }} Each August before the start of the tournament, the courts are resurfaced.{{cite news |url=https://www.nytimes.com/2011/09/08/sports/tennis/us-open-speed-bumps-on-a-hardcourt.html |title=Speed Bumps on a Hardcourt |author=Thomas Lin |newspaper=The New York Times |date=September 7, 2011 |access-date=August 25, 2018 |archive-date=July 2, 2021 |archive-url=https://web.archive.org/web/20210702164636/http://www.nytimes.com/2011/09/08/sports/tennis/us-open-speed-bumps-on-a-hardcourt.html |url-status=live }} In March 2020, the USTA announced that Laykold would become the new court surface supplier beginning with the 2020 tournament.{{cite web |url=https://www.tennis.com/pro-game/2020/03/us-open-changing-hard-court-brand-for-1st-time-since-1970s/88096/ |title=US Open Changing Hard-Court Brand for First Time since 1970S |agency=Associated Press |website=tennis.com |date=March 23, 2020 |access-date=July 25, 2020 |archive-date=January 27, 2021 |archive-url=https://web.archive.org/web/20210127045532/https://www.tennis.com/pro-game/2020/03/us-open-changing-hard-court-brand-for-1st-time-since-1970s/88096/ |url-status=live }}

Since 2005, all US Open and US Open Series tennis courts have been painted a shade of blue (trademarked as "US Open Blue") inside the lines to make it easier for players, spectators, and television viewers to see the ball. The area outside the lines is still painted "US Open Green".{{cite magazine |url=https://www.si.com/tennis/2015/08/21/how-us-open-makes-courts-colors-science |title=The science behind creating the U.S. Open courts and signature colors |author=Tim Newcomb |magazine=Sports Illustrated |date=August 24, 2015 |access-date=December 10, 2017 |archive-date=November 11, 2020 |archive-url=https://web.archive.org/web/20201111201342/https://www.si.com/tennis/2015/08/21/how-us-open-makes-courts-colors-science |url-status=live }}

In 2006, the US Open introduced instant replay reviews of line calls, using the Hawk-Eye computer system. It was the first Grand Slam tournament to use the system.{{cite magazine |last=Williams |first=Daniel |date=January 11, 2007 |title=Australian Open Preview |url=http://content.time.com/time/world/article/0,8599,1577215,00.html |access-date=March 1, 2021 |magazine=TIME |publisher=Time Warner |quote=As seen at last year's U.S. Open and numerous events since, this is the best innovation in tennis since yellow balls. |archive-date=August 11, 2016 |archive-url=https://web.archive.org/web/20160811181908/http://content.time.com/time/world/article/0,8599,1577215,00.html |url-status=live }} The Open felt the need to implement the system because of the controversial quarterfinal match at the 2004 US Open{{citation needed|date=August 2018}} between Serena Williams and Jennifer Capriati, where a number of important line calls went against Williams. Replays on TV showed these calls were incorrect, including one critical point in the match that was incorrectly overruled by the chair umpire.{{cite news |url=https://www.nytimes.com/2004/09/09/sports/tennis/williams-receives-apology-and-umpires-open-is-over.html |title=Williams Receives Apology, and Umpire's Open Is Over |author=Chris Broussard |newspaper=The New York Times |date=September 9, 2004 |access-date=February 20, 2017 |archive-date=May 25, 2021 |archive-url=https://web.archive.org/web/20210525010950/http://www.nytimes.com/2004/09/09/sports/tennis/williams-receives-apology-and-umpires-open-is-over.html |url-status=live }} Instant replay was available only on the Arthur Ashe Stadium and Louis Armstrong Stadium courts through the 2008 tournament. In 2009, it became available on the Grandstand court.{{citation needed|date=August 2018}} In 2018, all competition courts were outfitted with Hawk-Eye, and all matches in the main draws (Men's and Women's Singles and Doubles) followed the same procedure, whereby each player was allowed three incorrect challenges per set, with one more given in a tiebreak. Player challenges were eliminated in 2021, when the tournament became the second Grand Slam to fully incorporate Hawk-Eye Live, where all line calls are made electronically; the previous year's tournament had also incorporated Hawk-Eye Live on all courts except for Arthur Ashe and Louis Armstrong stadiums to reduce personnel during the COVID-19 pandemic.{{Cite web |date=September 6, 2021 |title=US Open 2021: 'Hawk-Eye Live' replaces line judge as technology takes over US Open; officials reduced from 400 to 130 |url=https://www.insidesport.co/us-open-2021-hawk-eye-live-replaces-line-judge-as-technology-takes-over-us-open-officials-reduced-from-400-to-130/ |access-date=September 8, 2021 |website=InsideSport |archive-date=September 7, 2021 |archive-url=https://web.archive.org/web/20210907095358/https://www.insidesport.co/us-open-2021-hawk-eye-live-replaces-line-judge-as-technology-takes-over-us-open-officials-reduced-from-400-to-130/ |url-status=live }}

In 2007, JPMorgan Chase renewed its sponsorship of the US Open and, as part of the arrangement, the replay system was renamed to "Chase Review" on in-stadium video and television.{{cite web |url=http://www.sportsbusinessjournal.com/article/55967 |title=Chase signs mega renewal with Open |access-date=September 9, 2016 |archive-date=February 13, 2021 |archive-url=https://web.archive.org/web/20210213071804/https://www.sportsbusinessdaily.com/Journal.aspx |url-status=dead }}

The total prize money for the 2023 US Open was $65 million and is the largest package of all Grand Slams and the largest in tournament history. The package is divided as follows:{{cite web |url=https://www.usopen.org/en_US/visit/prize_money.html |title=2023 US Open Prize Money |publisher=United States Tennis Association |access-date=August 18, 2023 |archive-date=August 8, 2018 |archive-url=https://web.archive.org/web/20180808072324/https://www.usopen.org/en_US/visit/prize_money.html |url-status=live }}

The men's and women's singles prize money ($44.7 million) accounts for 68.7 percent of total player base compensation, while men's and women's doubles ($7,133,600), men's and mixed doubles ($679,200) account for 11.0 percent and 1.0 percent, respectively. All prize money for the doubles competitions are distributed per team. The prize money for the wheelchair draw amounts to a total of $1,366,800, plus additional expenses, such as per diem and direct hotel payments of $4,656,420.

In 2012, the USTA agreed to increase the US Open prize money to $50.4 million by 2017. As a result, the prize money for the 2013 tournament was $33.6 million, a record $8.1 million increase from 2012. The champions of the 2013 US Open Series also had the opportunity to add $2.6 million in bonus prize money, potentially bringing the total 2013 US Open purse to more than $36 million.{{cite web |title=US Open makes long-term commitment to the game |url=http://www.usopen.org/news/us_open_makes_long-term_commitment_to_the_game/ |publisher=United States Tennis Association |access-date=June 25, 2013 |archive-date=September 10, 2021 |archive-url=https://web.archive.org/web/20210910045955/https://www.usopen.org/news/us_open_makes_long-term_commitment_to_the_game/ |url-status=live }} In 2014, the prize money was $38.3 million.{{cite web |title=2014 US Open Prize Money |publisher=United States Tennis Association |website=2014.usopen.org |url=http://2014.usopen.org/en_US/about/history/prizemoney.html |archive-url=https://web.archive.org/web/20150826081902/http://2014.usopen.org/en_US/about/history/prizemoney.html |archive-date=August 26, 2015}} In 2015, the prize money was increased to $42.3 million.{{cite news |date=July 14, 2015 |title=Game, set, cash: US Open prize money upped to 42.3 million dollars |publisher=Dpa International |url=http://www.dpa-international.com/news/sports2/game-set-cash-us-open-prize-money-upped-to-423-million-dollars-a-45953096.html |archive-url=https://web.archive.org/web/20150716115938/http://www.dpa-international.com/news/sports2/game-set-cash-us-open-prize-money-upped-to-423-million-dollars-a-45953096.html |archive-date=July 16, 2015}} In 2021, the USTA set a new record for the highest prize money and total player compensation in the tournament's history with $57,462,000 and also boosted the prize money for the qualifying tournament to $6 million, a 66% increase over the package in 2019.{{Cite news |date=August 23, 2021 |title=2021 US Open offers record prize money, $57.5 million in total player compensation |work=US Open |url=https://www.usopen.org/en_US/news/articles/2021-08-20/rafael_nadal_ends_season_due_to_foot_injury_withdraws_from_2021_us_open.html |access-date=September 11, 2021 |archive-date=August 25, 2021 |archive-url=https://web.archive.org/web/20210825121618/https://www.usopen.org/en_US/news/articles/2021-08-20/rafael_nadal_ends_season_due_to_foot_injury_withdraws_from_2021_us_open.html |url-status=live }}

The 2023 tournament saw another record, with total prize money reaching $65 million. Efforts were also undertaken to enhance support for participants across all events by implementing expanded player expense assistance measures. This iteration of the tournament introduced substantial changes in player per diem allowances, extending to all competitors. Notably, travel vouchers worth $1,000 have been newly introduced. Moreover, players can receive an additional hotel room or witness a twofold increase in their daily hotel allowance, which has been raised from $300 to $600, provided they choose alternate lodging. Additionally, an elevation in meal allowances and provision of racquet stringing services are also in effect for all participating players.{{Citation | year=2023 | title=US Open Prize Money 2023 | url=https://www.perfect-tennis.com/prize-money/us-open/ | access-date=18 August 2023 | archive-date=May 30, 2023 | archive-url=https://web.archive.org/web/20230530051429/https://www.perfect-tennis.com/prize-money/us-open/ | url-status=live }}
