John Isner height - How tall is John Isner?

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.

The longest match in history: Isner v Mahut, June 22–24, 2010

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 first three sets were all decided by tiebreakers, the first going to Anderson 7–6 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 line score reading 7–6, 6–7, 6–7, 6–4, 26–24.

Isner was the top seed and defeated Karol Beck, Arnaud Clément, Alex Bogomolov, Jr., and Tobias Kamke without dropping a set, to reach his first career grass-court final. In the final, he defeated Olivier Rochus to become the first top seed in 35 years to win the event.

Isner reached the fourth round of the French Open. At Wimbledon, he advanced to his first quarterfinal at a Slam in seven years since 2011 US Open. In the quarterfinal, Isner defeated Milos Raonic in four sets to advance to the first Grand Slam semifinal of his career, in which he lost to South African Kevin Anderson in a long five set match. This match lasted 6 hours and 36 minutes with a final score of 7-6, 6-7, 6-7, 6-4, 26-24, which was the fourth longest match in history and the second longest at a Grand Slam tournament behind Isner's first round defeat of Nicolas Mahut in 2010, also at Wimbledon. Isner adopting and working on an aggressive return style and a strong serve-and-volley game have been cited as reasons for his success in 2018 at Wimbledon.

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.

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.

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 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.

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.

Isner lost in the first round in Newport to eventual champion Rajeev Ram. He successfully defended his title in Atlanta in July to win his 10th ATP Tour title and third in a row at the tournament, defeating Marcos Baghdatis in the final in straight sets. The following week, he reached the final of the 500 tournament in Washington, D.C., losing in the final to Kei Nishikori. He also reached the quarterfinals of the Rogers Cup in Montréal, losing in three tiebreakers to Jérémy Chardy. However, the following week in Cincinnati, he bowed out in the first round against Sam Querrey. He then skipped Winston-Salem, his home tournament, the week before the US Open.

Isner has also earned a reputation for competing in extremely even, long duration matches and holds the unique distinction of having been a competitor in the longest and second longest matches in a major tournament in history. The first was the now legendary opening round match at the 2010 Wimbledon Championships when Isner defeated Nicolas Mahut in 11 hours, 5 minutes in a match played over three separate days. The second longest match in major tournament history was Isner's loss to South African Kevin Anderson in the first men's semifinal at the 2018 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, 7–6, 70–68.

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 also won the 2010 ESPY Award for Best Record-Breaking Performance in sport.

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, except the US Open, where there are no fifth-set tiebreaks, his matches can extend very long, as evidenced by the fact that he was a player in two of the longest Grand Slam matches, both at Wimbledon in 2010 and 2018 respectively.

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.

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'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.

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.

Isner began his professional career in earnest in the summer of 2007. With a world ranking of no. 839, he needed wildcard entries into the main draws of every tournament, even at Futures level.

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 Reily Opelka), Isner also lost in the first round of doubles.

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.

John Robert Isner (born April 26, 1985) is an American professional tennis player who has been ranked as high as No. 8 in men's singles 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 semifinals 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 his first ATP Finals appearance later that year. He currently has the second-most aces in the history of the ATP Tour, having served over 12,000 aces. At the 2010 Wimbledon Championships, he played the longest professional tennis match in history, defeating Nicolas Mahut in a total of 11 hours and 5 minutes, played over the course of three days.

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.
