2007–2008: The beginnings on the World Tour

In the summer of 2007, Isner began his professional career on the ATP tour. In his only short professional career, he has already won a Challenger and a Future tournament, the second and third class tournament categories. His greatest success at the beginning of his career was at the ATP tournament in Washington, DC , where he - due to a back injury to Fernando González - made it into the main draw with a wild card. Although he only started the tournament as number 416, he defeated Tim Henman , Benjamin Becker , Wayne Odesnik , Tommy Haas and Gaël Monfils one after the other and reached the final, in which he was defeated 4: 6, 6: 7 Andy Roddick . Isner's greatest strength, due to his height of 2.08 m, is his serve with which he hit 144 aces in the course of the tournament and won all his matches in the tie-break of the third set on the way to the final . With this success he made it to number 193 in the world rankings. In addition, he received a wildcard for the subsequent tournaments in Cincinnati and New Haven , but failed in the first and second round each to David Ferrer . At the US Open , Isner reached the third round after victories over Jarkko Nieminen and Rik De Voest , in which he failed against the number one in the world, Roger Federer , in four sets. He was only one of two players who won a set against Federer in the course of the tournament.

Personal and curious

Isner studied speech communication at the University of Georgia and has two older brothers.

After his victory over Tommy Haas, the German jokingly asked for a size limit for ATP players. With a height of 2.08 m, Isner is the second tallest player on the ATP tour after the Croatian Ivo Karlović .

On June 24, 2010, Isner and Frenchman Nicolas Mahut set a historic record in the first round match at Wimbledon . Only after a total playing time of eleven hours and five minutes was the match decided in Isner's favor. The decisive fifth set lasted over eight hours and ended 70:68. The game had already started on June 22nd. Because of falling darkness, however, she was interrupted twice - after the fourth and at 59:59 in the fifth set. The game set new records not only in terms of length, but also in terms of the number of aces: Isner got 112, Mahut 103 aces. Never before had a player reached a three-digit number of aces in a match.

In 2011 the two met again in the first round at Wimbledon. This time the game was decided in three sets: Isner won 7: 6 (7: 4), 6: 2 and 7: 6 (8: 6).

On July 13, 2018, Isner also played the second longest Wimbledon match in history. In a playing time of 6:36 hours and five sets (6: 7 (6: 8), 7: 6 (7: 5), 7: 6 (11: 9), 4: 6, 24:26) he lost against Kevin Anderson in the longest semifinals of the tournament. He holds the record for the longest and third longest match in tennis history.

On March 6, 2016, Isner hit in his Davis Cup match against Bernard Tomic at 253 km / h, with which he achieved the fastest measured serve above the Challenger Tour level. Before that, Ivo Karlović (251.4 km / h) had held the record. Samuel Groth holds the record of the fastest serve with 263 km / h, which he set up on the Challenger Tour.

In December 2017, he married his longtime girlfriend, Madison McKinley.
