John Robert Isner (born April 26, 1985) is an American professional tennis player. Considered one of the best servers of the ATP World Tour, Isner achieved his career-high singles ranking of world No. 9 in April 2012. In 2013, he became the 18th player to serve more than 5,000 aces on the ATP World Tour. He currently has 4th-most aces in the history of ATP, having served more than 8,800 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 of play over the course of three days. He also played the then 10th-longest singles match, a 5-hour 41-minute encounter in the second round of the 2012 French Open.

Isner has an extremely powerful and consistent serve, thanks in part to his 6-ft 10-in height which makes him the third tallest player on tour behind Ivo Karlovic and Reilly Opelka. Commentators 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 fitness has improved considerably throughout the years, as he displayed during his win in the longest tennis match ever at Wimbledon against Nicolas Mahut.
