John Robert Isner (born April 26, 1985) is an American professional tennis player. He has been ranked as high as world No. 8 in singles and No. 14 in doubles by the Association of Tennis Professionals (ATP).
Considered one of the best servers ever to play on the ATP Tour, Isner achieved his career-high singles ranking in July 2018 by virtue of his maiden Masters 1000 crown at the 2018 Miami Open and a semifinal appearance at the 2018 Wimbledon Championships. He has also twice reached the quarterfinals at the US Open in 2011 and 2018, the latter of which helped qualify him for an ATP Finals appearance later that year. At the 2010 Wimbledon Championships, he played the longest professional tennis match in history, requiring five sets and 183 games to defeat Nicolas Mahut in a match which lasted 11 hours and 5 minutes, and was played over the course of three days. Isner holds the record for hitting the ATP's fastest "official" serve ever and third-fastest on record in tennis at 157.2 mph or 253 km/h during his first-round 2016 Davis Cup match. He has the most aces in the history of the ATP Tour, having served 13,854, as of August 1, 2022.
Isner was born on April 26, 1985 in Greensboro, North Carolina to Robert and Karen Isner. He has two older brothers, Jordan and Nathan.
Isner started playing tennis at the age of 9 and did not take the sport seriously until the age of 11. He played for his high school of Walter Hines Page Senior High School where he helped lead them to a state championship in 2001. He also played in 10 junior tournaments which included the 2002 US Open (losing in the second round to eventual champion Richard Gasquet) and the 2002 Orange Bowl. He also made the finals of a tournament in Tulsa, Oklahoma losing to Brian Baker.
Coming out of high school in 2003 as a heavily sought-after prospect, Isner was recruited by the University of Georgia Bulldogs. He was a dominance in college, compiling a win-loss record of 143–28 in singles and 140–27 in doubles. He was ranked the top tennis player in the country on numerous occasions and won many tournaments. Some highlights from his college career include winning the 2005 NCAA doubles title parterning Antonio Ruiz-Rosales, winning the 2007 team event against Illinois and reaching the 2007 NCAA singles finals where he lost to Somdev Devvarman of Virginia in three sets.He ended his college career after his singles final loss and team win in 2007 and turned professional.
Isner began his professional career in earnest in the summer of 2007. With a world ranking of no. 839, he needed a wildcard entry into the main draws of every single tournament, even at Futures level.
He won his first tournament of the summer, the USA F14 Futures, beating the top three seeds along the way. Then, after first-round losses at Challenger level as well as a tournament at ATP level, he beat five top-300 players and three seeds to win the Lexington Challenger in July and improve his ranking to no. 416 after just one month.
At the following week's tournament at the Legg Mason Tennis Classic in Washington, D.C., a late withdrawal freed up a wildcard spot, which was given to Isner at the last minute. Isner took full advantage of his good fortune, recording his first wins over top-100 players. He won third-set tiebreakers on five consecutive days, beating no. 73 Tim Henman, no. 47 Benjamin Becker, no. 189 qualifier Wayne Odesnik, no. 12 Tommy Haas, and no. 54 Gaël Monfils, to reach the final, where he fell to fellow American Andy Roddick. His week raised his ranking to no. 193 in the world after six weeks on the pro tour.
Isner's success in Washington, D.C. earned him wildcard entries into three more ATP tournaments—the Masters 1000 Series event in Cincinnati a week later, New Haven and the US Open. He lost in the first round in Cincinnati to quarterfinalist no. 15 David Ferrer. The following week in New Haven, he beat no. 49 Becker a second time, before falling to Ferrer for the second week in a row.
In his US Open début, he defeated the 26th-seeded player, former quarterfinalist Jarkko Nieminen, firing 34 aces along the way. He proceeded to win his second-round match against Rik de Voest, before losing in the third round to top seed and eventual champion Roger Federer. Isner was one of only two players to take a set from Federer in the championship. His US Open performance improved his ranking to no. 144.
After the US Open, Isner continued to play exclusively in North America and finished the year ranked no. 107. That year, Isner was added to the United States Davis Cup team as a practice partner.
Isner's no. 106 ranking in November 2007 was just good enough to get him direct entry into his first Australian Open after several players ranked above him dropped out. He was defeated in the first round of the 2008 Australian Open by veteran Fabrice Santoro of France. Teamed with Croat Ivo Karlović, who stands half an inch taller (Karlović is currently the joint tallest player on the ATP World Tour alongside Reilly Opelka), Isner also lost in the first round of doubles.
Isner broke into the top 100 at no. 93 in February with a quarterfinal appearance at an ATP event in San Jose, beating no. 90 Florent Serra and no. 26 Tommy Haas. He maintained a top-100 ranking in the first three months of the year, beating six players in the top 100, while playing exclusively in events at ATP level. Isner played at his first French Open and Wimbledon, losing in the first round of each. He also played at the US Open, where he lost in the first round. He ended the year ranked no. 144 in the world.
Isner qualified for the singles draw of the 2009 Heineken Open in Auckland, after winning three consecutive three-set matches in qualifying. His final match saw him bounce back from a 0–3 deficit in the third set to eventually beat Brazilian Thomaz Bellucci in a tiebreaker. In the main draw, Isner beat Albert Montañés and countryman Robby Ginepri, before ultimately exiting with a loss in the quarterfinals.
Isner received a wildcard into the 2009 Australian Open, after winning the United States Tennis Association's wildcard tournament, beating Donald Young and Jesse Levine along the way. Despite serving 39 aces against his first-round opponent, Slovakia's Dominik Hrbatý, he lost in four sets. Isner began working with a new coach, Craig Boynton, who had coached former world no. 1 Jim Courier in the 1990s, in March 2009.
At the 2009 Indian Wells Masters, Isner pulled off a major upset by defeating ninth seed Gaël Monfils. This was Isner's first win over a top-10 player, after four previous defeats. He then went on to defeat former world no. 1 Marat Safin, before losing to world no. 6 Juan Martín del Potro in the fourth round.
In April 2009 at the U.S. Men's Clay Court Championships in Houston, Texas, at River Oaks Country Club, Isner made it as far as the quarterfinals, where he was defeated by fellow American Wayne Odesnik. Isner qualified for the French Open, but had to withdraw after being diagnosed with mononucleosis, which caused him to miss Wimbledon as well.
In August 2009, he defeated world no. 7 Jo-Wilfried Tsonga and world no. 18 Tomáš Berdych en route to the semifinals of the ATP World Tour 500 event in Washington, before losing to world no. 5 Andy Roddick. This performance brought him to a career-high ranking of no. 55 and a special exemption into the Masters 1000 Series event in Montreal, where he defeated Jesse Levine, before losing to Mikhail Youzhny. He earned a wildcard into the Masters 1000 Series event in Cincinnati, where he defeated world no. 21 Tommy Haas, before losing to world no. 35 Jérémy Chardy in the second round.
Unseeded and ranked no. 55 in the world entering the US Open, Isner defeated world no. 29 Victor Hănescu in the first round, which was his first win in a Grand Slam tournament since the 2007 US Open, ending a streak of six consecutive defeats. He then advanced to the third round, where he defeated world no. 5 and fellow American Andy Roddick in five sets for his first victory over Roddick, his first victory in a five-set match, and the first time he advanced past the third round of a Grand Slam tournament. He was then defeated in the fourth round by world no. 10 Fernando Verdasco in four sets. His US Open performance brought his ranking to a career-high no. 39.
After playing in Vienna, Basel and at the Paris Masters, Isner finished the year at a career-high no. 34 in the world. He has credited his work with Boynton for helping him get back on track following his disappointing 2008 season.
His progress was acknowledged by his peers, as he was voted the ATP Most Improved Player for 2009, becoming the tenth American to win the award, and the first since Andre Agassi in 1998.
Isner began the year at the 2010 Heineken Open in Auckland. Unseeded, he reached his second career ATP final and first since Washington in 2007. In the final, he saved a championship point to defeat 2001 Australian Open finalist Arnaud Clément. The victory in Auckland was Isner's first ATP tour title; after the victory he donated $5,000 of his winnings to aid rescue action for the 2010 Haiti earthquake.
The victory catapulted Isner into the top 30 for the first time and also allowed him to surpass Sam Querrey to become the second-highest-ranked American for the first time, behind only Andy Roddick. Isner said he intended to finish the year in the top 20, and given his ascendency in the world rankings combined with the absence of Roddick and James Blake for the 2010 Davis Cup season, it became increasingly likely that Isner would qualify to play singles for the United States Davis Cup team for the first time in his career.
After Gilles Simon withdrew, Isner became the final seed for the 2010 Australian Open. In the first round, he defeated world no. 49 Andreas Seppi for his first victory at the Australian Open and his first victory at a Grand Slam other than the US Open. He then advanced to the round of 16, before losing to world no. 4 and eventual finalist Andy Murray.
After the Australian Open, Davis Cup captain Patrick McEnroe announced that Isner and Querrey would be first and second singles selections on the United States Davis Cup team's first-round World Group tie in Serbia on indoor clay in March 2010; Isner described the selection as "a dream come true".
Isner next entered the 2010 Regions Morgan Keegan Championships in Memphis. Seeded sixth, he made it to the finals, before losing to Sam Querrey. In the doubles event, Isner teamed up with Querrey to win the tournament, defeating the British-Australian pair of Ross Hutchins and Jordan Kerr.
Prior to the Davis Cup tie, Isner competed at the 2010 Abierto Mexicano Telcel Championships, an ATP World Tour 500 event on clay, where he was the fifth seed. He lost in the first round to Simon Greul. Despite the loss, Isner following the tournament moved into the top 20 for the first time.
Isner appeared in the first round of the 2010 Davis Cup, where the United States was up against Serbia. In his two singles matches, he faced Serbia's team of world no. 2 Novak Djokovic and world no. 35 Viktor Troicki. He lost the first singles match against Troicki, but bounced back by winning the doubles match with Bob Bryan, as a replacement for food-poisoned Mike Bryan. In his second singles match, he lost to Djokovic, which enabled Serbia to defeat the United States.
At the 2010 BNP Paribas Open in Indian Wells, he was seeded 15th and advanced to the fourth round, before losing to world no. 2 and defending champion Rafael Nadal.
Afterwards, he appeared as the 17th seed at the second Masters 1000 Series event of the season—the 2010 Sony Ericsson Open in Miami. He advanced to the third round, before losing to 12th seed Juan Carlos Ferrero.
Isner began the clay-court season with an opening-round loss to world no. 89 Xavier Malisse at the U.S. Men's Claycourt Championship, followed by a round of 32 showing at his first-ever Internazionali BNL d'Italia, where he defeated Horacio Zeballos, before losing to Thomaz Bellucci. However, he teamed with Querrey to reach the doubles final in Rome, before losing to Bob and Mike Bryan; his doubles performance raised his doubles ranking to the top 30 for the first time.
His next tournament was the 2010 Serbian Open, where he was the second seed behind defending champion, tournament host and world no. 2 Djokovic. Isner advanced to the first clay-court final of his career, third final of the year, and fourth final of his career. In the final, he lost to Querrey, despite having a match point; this was the second consecutive final Isner lost to Querrey after serving for the championship. However, Isner's finals performance improved his ranking to a career-high no. 19.
Isner's next tournament was his debut appearance at the Mutua Madrileña Madrid Open. Seeded thirteenth, he advanced to the round of 16, before losing to world no. 3 and eventual champion Nadal.
Isner then played at the 2010 French Open; his ranking assured his first direct seed into a Grand Slam event. Seeded 17th, he defeated Andrey Golubev in the first round for his first singles victory at the French Open. He advanced to the third round, before losing to the no. 15 seed and eventual semifinalist Tomáš Berdych. In doubles, he and Querrey were the 12th seeds, but withdrew prior to the start of the tournament after Querrey's first-round loss in singles.
Despite being ranked no. 19 in the world entering Wimbledon, Isner was seeded 24th by the tournament committee due to his lack of experience on grass, but was moved up to 23rd following the withdrawal of Radek Štěpánek. In the first round, Isner played Nicolas Mahut in the longest match in tennis history, prevailing 6–4, 3–6, 6–7, 7–6, 70–68. However, fatigued and having little time to recover his energy, Isner was beaten by Thiemo de Bakker in the second round, 0–6, 3–6, 2–6, having served no aces. He also pulled out of the doubles, where he and Querrey had been 12th seeds. Despite having been eliminated in the second round, Isner's total of 113 aces were more than any other player throughout the championship. His Wimbledon performance brought his ranking to a career-high no. 18 in the world.
Isner's next tournament was the 2010 Atlanta Tennis Championships, where he played doubles with James Blake and reached the semifinals. In singles, Isner was second seed and made it to his fourth final of the year, before losing to Mardy Fish, which dropped his career record in finals to 1–4 (0–4 against Americans).
Isner next competed at the 2010 Legg Mason Tennis Classic, the ATP World Tour 500 series event in Washington, D.C. and site of his breakthrough performance in 2007. Isner was to also compete in the doubles with Sam Querrey, but withdrew due to shoulder concerns. Seeded fifth in singles, Isner made it to the round of 16, before losing to Xavier Malisse.
Isner next played at the 2010 Cincinnati Masters, where he was unseeded. After defeating Łukasz Kubot in the first round, he faced 2002 Wimbledon finalist and 2005 Tennis Masters Cup champion David Nalbandian, but was forced to retire up a break at 5–4 in the first set after injuring his right ankle. Although Isner was found to have suffered ligament damage to the ankle, he chose not to withdraw from the US Open singles tournament.
At the 2010 US Open, Isner was 18th seed and defeated Frederico Gil in the first round. After the match he revealed that although the initial diagnosis was a right ankle ligament tear, a second opinion revealed that the damage was a strain and not a tear, and he declared his ankle 90% healed. He then advanced to the third round, before losing to 12th seed and 2006 US Open semifinalist Mikhail Youzhny. The loss dropped Isner out of the top 20 and from the no. 2 to the no. 4 ranked American player. Due to his ankle injury, he chose not to compete in doubles.

In the final, he defeated Olivier Rochus to become the first top seed in 35 years to win the event.

Isner started the US Open Series with a disappointing loss in the second round of the 2016 Rogers Cup to Ryan Harrison. Isner rebounded by reaching his first final of the season and his fourth consecutive final at the Atlanta Open, losing in straight sets to Nick Kyrgios. Isner skipped the Summer Olympics due to it lacking ranking points and prize money, electing to focus on the summer hardcourt tournaments of the US Open Series. After Isner lost in straight sets in the second round to Milos Raonic and Steve Johnson reached the quarterfinals in Cincinnati, Isner lost the title of the top-ranked American man for the first time in three years. Although he regained it in the following week, Johnson took it back again following the 2016 US Open, after Isner was unable to defend his fourth-round points, losing in the third round to Kyle Edmund in four sets.
Isner teamed up with Jack Sock to win his second Masters doubles title and fourth overall doubles title at the 2016 Shanghai Masters. Unseeded at the final regular tournament of the season, Isner would prevail against seeded players David Ferrer and Marin Čilić to reach his third Masters final and second final of the season at the 2016 BNP Paribas Masters in Paris. His semifinal victory allowed him to again finish the year as the no. 1 American for the fifth consecutive year and inside the top 20 for the seventh consecutive season.

The longest match in history: Isner v Mahut, June 22–24, 2010
Main article: Isner–Mahut match at the 2010 Wimbledon Championships
At the 2010 Wimbledon Championships, Isner faced qualifier Nicolas Mahut in the first round. Isner won the match 6–4, 3–6, 6–7(7–9), 7–6(7–3), 70–68.
The final set alone was longer than the previous longest match.
In the match, Isner set the record for the most aces served in a match, breaking Ivo Karlović's record of 78; Mahut passed the old mark as well. Isner set a new record of 113 aces, ahead of the 103 aces served by Mahut.
The first four sets were played on June 22. At 21:13 BST on June 23 the match was suspended due to darkness for a second day at 59–59 in the fifth set. The match resumed on June 24, at 15:30 BST, starting the third day of the match. Overall, the match lasted eleven hours and five minutes. Isner also set the record for the most games won in a Wimbledon match with 92.
The match brought Isner a measure of fame, particularly in the United Kingdom and his native United States. He had guest appearances on Good Morning America and the Late Show with David Letterman, and threw the ceremonial first pitch at a New York Yankees game in Yankee Stadium. He and Mahut won the 2010 ESPY Award for Best Record-Breaking Performance in sport.

The second-longest match: Isner v Anderson, July 13, 2018
This match saw Isner face similarly big-serving Kevin Anderson of South Africa. The match is the longest tennis match ever in the second week of a Grand Slam tournament, both by time and number of games played. It is also the longest-ever match on Centre Court, and the fourth-longest tennis match of all time.
The first three sets were all decided by tiebreakers, the first going to Anderson and both the second and third going to Isner. In the fourth set Anderson exploited an opening and broke Isner's serve to make the score 7–6, 6–7, 6–7, 6–4 going into a fifth set in which Anderson seemed to have gained significant momentum from his service break. The fifth quickly became a battle of services as both players began to tire. At 16–17 it began to rain, leading to speculation of a delay to close the Centre Court roof, but the rain stopped during the crossover break. Isner endured a shaky mistake which permitted Anderson to get back in the game to 40–30 from 40–0 down, but Isner forced Anderson to miss the next backhand return and held serve. At 24–24, Anderson built up a 0–40 lead and while Isner got back two of those points to bring the score to 30–40, Anderson broke Isner on his third break point of the game, and served out to win the match in 6 hours and 36 minutes, with the scoreline reading 7–6, 6–7, 6–7, 6–4, 26–24.

Isner has an extremely powerful and consistent serve, thanks in part to his 6-foot-10½-inch height which makes him the third-tallest player on tour behind Ivo Karlović and Reilly Opelka. Commentators[who?] have also praised his composure; in five consecutive third-set tiebreaker wins in Washington, D.C., he delivered huge serves when it mattered most. Isner also has a very powerful forehand, which he uses in tandem with his serve. Isner will often go for one-two points: a big serve followed up by a big forehand. He is also known to back up his serves with approaches to the net, though he does not strictly serve-and-volley. Isner's movement around the court is hampered by his body and he is hurt by players that move him around the court. Isner's fitness has improved considerably throughout the years, as he displayed during his win in the longest tennis match ever at Wimbledon against Nicolas Mahut.
Because of his style of play, that consists of a big, consistent serve, he often ends up winning a great majority of his service games. But at the same time, due to poor movement around the court, he often finds it difficult to break the opponent's serve, especially those players that move him around the court. This often finds him involved in long matches where each player continues holding serve until the set reaches the tiebreak. At Grand Slams with no fifth-set tiebreaks, his matches could extend very long: he played in the two longest Slam matches during the 2010 and 2018 Wimbledon Championships. In 2022 all slams adopted 10-point fifth-set tiebreakers, so these records may stand until the rule is again changed.
As of January 2012, Isner was sponsored by Lacoste and Prince for his attire and rackets, respectively. His attire carried through most of 2015. He switched his attire to FILA in 2016 at the Australian Open.
Isner's first coach was Craig Boynton, who worked with him from 2009 to 2012 and helped develop his style of play. Isner and Boynton split over reportedly mutual agreement. Isner then hired Mike Sell, who helped him to significant success, such as defeating Roger Federer, David Nalbandian and Novak Djokovic. During his time with Sell, Isner's ranking stayed around no. 10 in the world. After parting from Sell in 2014, Isner teamed with Justin Gimelstob and worked with him until April 2016. With Gimelstob, Isner's ranking stayed around 10, until 2016, where he dropped to 17. As of 2018, he is currently working with coaches Rene Moller and David Macpherson.
While at the University of Georgia, Isner majored in speech communication. He resided in Tampa, Florida, where he trained at the Saddlebrook Academy alongside other American tennis pros such as James Blake and Mardy Fish. Currently, he resides in Dallas, Texas.
Isner married Madison McKinley, a jewelry designer, on December 2, 2017, in Bluffton, South Carolina. They have three children.
