John Isner saddened the tennis world when, moments before the start of the US Open, he announced that it would be his last tournament of his career. Even though the American puts down his racket, tennis will remember him. There is a high probability that some of his records will remain unbroken.

John Isner is an American tennis player known to every tennis fan. This is rare because we tend to be selective. However, Isner cannot be ignored. 208 centimeters tall. Ace serving machine. Winner of the longest match in tennis history. These are just a few reasons why the tennis world will miss him when the American puts down his racket after the US Open.

While Isner has never won a grand slam, he has several tennis records that perhaps no one can beat. So far in his career, Isner has served a record 14,411 aces. In total, he won 16 singles titles. He also competed in the longest tennis match ever at Wimbledon in 2010, beating Nicolas Mahut 6-4, 3-6, 6-7, 7-6, 70-68 in 11 hours and five minutes. Isner then served a record 113 aces, and the match lasted three days and ended in a fifth set consisting of 138 games. He also achieved his best result in a grand slam at Wimbledon, where in 2018 he reached the semi-finals. In 2023, he became the first tennis player in history to record 500 tie-break wins.

In 2018, he recorded a career-high eighth place in the world ranking. From 2010, he was in the top 20 of the ranking for the next ten years.

We’re curious to see how much he’ll improve his ace record in his farewell US Open.
