John Robert Isner (born April 26, 1985) is an American professional tennis player. He achieved his career-high singles ranking of world no. 9 on March 19, 2012, and is currently the second highest-ranked male American tennis player at no. 22, behind Sam Querrey. His most famous victories were against Roger Federer in the Davis Cup encounter in February 2012, top seed Novak Djokovic at the 2012 Masters 1000 tournament in Indian Wells, Andy Roddick in the 2009 US Open, and against Nicolas Mahut at the 2010 Wimbledon Championships where he played the longest professional tennis match in history, which lasted 11 hours and 5 minutes over the course of three days. He also played in the 10th-longest match—a 5 hour 41 minute match in the second round of the 2012 French Open.
Collegiate career 
Isner played collegiate tennis at the University of Georgia from 2004 to 2007 and became the school's all-time leader in singles and doubles victories, earning All-American honors each of his four years and leading Georgia to the 2007 NCAA championship. During college John developed the name "The Big Fella."
Professional career 
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 the Futures level.
He won his first tournament of the fall, the USA F14 Futures, beating the top three seeds along the way. Then, after first round losses in a Challenger-level and an ATP-level tournament, he beat five top-300 players and three seeds to win the Lexington Challenger in July to 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., Fernando González's late withdrawal freed a wildcard spot, which was given at the last minute to Isner. 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 incredible week raised his ranking to no. 193 in the world after just six weeks on the pro tour.
Isner's Washington success earned him wildcard entries into three more ATP tournaments: the Masters 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 debut, he defeated the 26th-seeded player, former quarterfinalist Jarkko Nieminen, and fired 34 aces along the way. He proceeded to win his second round match vs. 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.
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 (2 cm taller than John, Ivo is currently the tallest player on the ATP tour), 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 the ATP stop in San Jose, beating no. 90 Florent Serra and no. 26 Tommy Haas. He established himself as a top-100 player in the first three months of the year, beating six players in the top 100, while playing exclusively in ATP-level events. Isner played in his first French Open and Wimbledon, losing in the first round of each. He also played in 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 tie-breaker. In the main draw, Isner beat Albert Montañés and countryman Robby Ginepri, before bowing out in the quarterfinals to Robin Söderling.
Isner received a wildcard entry 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 new coach, Craig Boynton, who had previously coached former world no. 1 Jim Courier in the 1990s, in March 2009.
At the 2009 Indian Wells tournament, 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 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 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 US 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 on the 2010 United States Davis Cup team for the team's 2010 Davis Cup World Group first-round match 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 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 series 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 at the 2010 Davis Cup first round, where USA 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 Viktor 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 Novak Djokovic, which enabled Serbia to defeat the United States.
Afterwards, he appeared in the second master series tournament of the season, the 2010 Sony Ericsson Open Masters 1000 in Miami as the 17th seed. 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 Rome Masters, 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 while serving up 6–3, 5–4; 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 Madrid Masters. Seeded thirteenth, he advanced to the round of 16, before losing to world no. 3 and eventual champion Nadal.
Isner then played in 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 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 the 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 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 also to 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 in the 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.
Following the US Open, Isner participated with Mardy Fish and Sam Querrey in the Davis Cup tie against Colombia, winning the doubles match with Fish as his partner. The US won the match 3–1 to remain in the 2011 Davis Cup world group. Isner was next granted a wildcard to participate in the 2010 China Open, his first time competing in Beijing. In doubles, he teamed with Querrey, losing in the first round to Bob and Mike Bryan. In singles, Isner was unseeded, but made it to the semifinals, before losing to world no. 2 and defending champion Novak Djokovic 6–7, 2–6. Isner next competed in the Shanghai Masters, where he was unseeded, and made it to the second round, before losing to world no. 3 and reigning Australian Open champion Roger Federer in their first meeting since the 2007 US Open.
Following his win in Perth, Isner returned to Auckland to defend his ATP title at the 2011 Heineken Open. After a bye in his first round, the third seed faced Dutch world no. 52 Robin Haase. Isner defeated Hasse to go through to the quarterfinals, where he was defeated by David Nalbandian in straight sets.
Isner next played in the Australian Open. He entered the tournament seeded 20th and received a tough draw, including Radek Štěpánek, Marin Čilić, and Rafael Nadal. Isner came up against French world no. 69 Florent Serra, whom he easily defeated. Isner faced Radek Štěpánek in the second round. After losing the first set, Isner rallied to defeat Stepanek to progress into the third round. In the third round, Isner faced fellow top-20 player Marin Čilić. The match went to five sets, with Cilic emerging as the eventual winner.
At the 2011 French Open, Isner was drawn against top seed and defending champion Rafael Nadal. Isner took what was considered a surprise two-sets-to-one lead against Nadal, who had never played a five-set match at Roland Garros before. Nadal went on to win the title. Ironically, in the 2011 Wimbledon men's singles draw, Isner was paired against Mahut in the first round, a rematch of the world's longest match from the previous year's tournament, which he went on to win in straight sets. However, he lost in the second round to the 16th seed Nicolás Almagro in four sets, dropping his 2011 record to 11–14.
Isner next took a last-minute wild card to participate in the 2011 Hall of Fame Tennis Championships, replacing compatriot and defending champion Mardy Fish, who was chosen to play in the Davis Cup for the United States during the that weekend. Isner was the top seed and defeated Karol Beck, 2001 Australian Open finalist 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. The title was his first of 2011 and second of his career, raising his record in ATP finals to 2–0 against non-Americans, and ending a three-match losing streak in finals. The championship raised Isner's world ranking from no. 48 to no. 36.
Isner next played in the 2011 Atlanta Tennis Championships, where he was the third seed. He defeated James Blake, Lu Yen-hsun, and Gilles Müller to reach his second consecutive tour final. In the final, he faced Mardy Fish in a rematch of the 2010 final. Isner was ultimately defeated by Fish. He then reached the semifinals of the Legg Mason Tennis Classic, defeating Tobias Kamke, James Blake, Victor Troicki, before losing to Gaël Monfils.
At the Rogers Cup, Isner defeated Marcos Baghdatis, but lost to Viktor Troicki in the second round. Isner won the Winston-Salem Open as the fourth seed, defeating Dudi Sela, Jarkko Nieminen, Marcos Baghdatis, and Andy Roddick in the semifinals, before defeating Julien Benneteau in the final.
John reached the semifinals at the Master's 1000 in Paris, where he held three match points before losing to Jo-Wilfried Tsonga in the semifinals. The result brought him back into the world top 20. He finished the year ranked no. 18, his second consecutive year-end top 20 ranking, and his highest year-end ranking to date.
John defeated David Nalbandian in the second round of the 2012 Australian Open in an epic five-set match, but was defeated in the third round by Feliciano López. He kept his good form and stunningly beat world no. 3 Roger Federer in Switzerland in the Davis Cup first round, as well as beating Marco Chiudinelli in another singles rubber, to help propel the US team to victory over the Swiss. He then reached the final of the Indian Wells Masters by beating world no. 1 Novak Djokovic in three sets in the semifinals, before being defeated by Federer in straight sets in the final. Isner also reached the doubles final of the same tournament partnering Sam Querrey.
Isner continued his fine form in the U.S. Davis Cup Quarterfinals against France. Isner defeated Gilles Simon in the first live rubber of the tie in straight sets. Two days later, Isner clinched the tie and propelled the United States into the semifinals by defeating French no. 1 Jo-Wilfried Tsonga in four sets.
In the French Open, he defeated Rogério Dutra da Silva 6–3, 6–4, 6–4 in the first round before being defeated by wildcard Paul-Henri Mathieu in the second round: 6–7, 6–4, 6–4, 3–6, 18–16 in the second-longest ever Roland Garros match at 5 hours and 41 minutes.
In the Wimbledon Championships, he was the eleventh seed, being the second top seed among the United States players. However, he was upset by 73rd ranked Alejandro Falla in five sets, being eliminated in the first round. Ironically, if he had won this match, he would have gone on to face Mahut for the third straight year. He beat Mahut 6–2, 7–6 at the Hall of Fame Tennis Championships in July, on his way to winning the championship for the second consecutive year.
Isner reached the semifinals at the 2012 Atlanta Tennis Championships, losing to Andy Roddick, 4–6, 7–6, 4–6. John defeated Raonic in the Rogers Cup (ATP 1000) quarterfinals and played Richard Gasquet for a place in the final, but lost
Isner was seeded first in Sydney, but he lost in the second round to Ryan Harrison in straight sets. He did not appear at the Australian Open the following week because of a bone bruise in his right knee.
John, won his sixth ATP title and first on clay, defeating Nicolás Almagro in the US Clay Court Championships final (Houston), 6-3, 7-5. He made the long trip to Monte Carlo for the Masters 1000 event there, but was eliminated in the first round. He also made early exits in Madrid and Rome.
Longest match in history 
In the match, Isner set the record for most aces in a match, breaking Ivo Karlović's record of 78; Mahut passed the old mark as well. Isner served an all-time record of 113 aces, ahead of the 103 aces served by Mahut.
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 most games won in a Wimbledon match with 92.
The match brought Isner a measure of fame, particularly in the 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.

Playing style and equipment 
Isner has an extremely powerful and consistent serve, thanks in part to his 6-ft, 9-in (206 cm) height. Only Ivo Karlović is taller among the current players. Commentators[who?] have also praised his composure; in five consecutive third-set tiebreaker wins in Washington, 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.
Personal life 
Isner was born in Greensboro, North Carolina. He has two older brothers, Nathan and Jordan. Isner started playing tennis seriously at age 11 under the tutelage of Oscar Blacutt and Rob Stephens. He played competitively for Westside Swim and Tennis Club in Greensboro throughout his childhood. He is a graduate of Walter Hines Page Senior High School, in Greensboro, and the University of Georgia, where he majored in Speech Communication. He currently resides in Tampa, Florida, where he trains at the Saddlebrook Academy alongside other American tennis pros such as James Blake and Mardy Fish.
