On-court achievements

Isner's best performance at the Grand Slam events came at the 2018 Wimbledon Championships, where he reached his maiden major semifinals.

John Isner has also been part of both the longest and the second-longest matches in tennis history - the 2010 Wimbledon first-round match against Nicolas Mahut, which went on for more than 11 hours, and the 2018 Wimbledon semifinal against Kevin Anderson.

He also has the record of hitting the most aces in a single match - 113 aces. The American also stands alone in the record of hitting the most aces in a single set - 85 aces.

Isner has 16 ATP singles titles, with his biggest title coming at the 2018 ATP Miami Masters. He also has five titles at the Atlanta Open.

Isner started his 2020 season strongly, reaching the semifinals in Auckland and Acapulco.

Later, he could not find his range after the tour's resumption following the lockdown enforced by the coronavirus pandemic. The former world number 8 started his 2021 season with a quarter-final run in Delray Beach. His overall performance in 2021 was nothing to write home about, although it was a big improvement over his 2020 season.

2022 was similar to the 2021 season, where Isner reached round three in two grand slams. However, he achieved a record for aces and sustained his top 15 rank in doubles. Coming into 2023, Isner is unfortunately not faring any better. He has exited all slams and masters in the first round. The US Open is the final chance for the player to do any better.
