introducing a tie break when the score in the fifth set (third set for women's matches) reaches 12-12. A further rule change during 2022 is trialing a 10-point tie break in the final set of all Grand Slam matches, meaning that under current rules, the Isner–Mahut match will likely remain the longest match in tennis history. Background The match took place during the 2010 edition of the 13-day Wimbledon Championships, held every June and July. Mahut, who was not ranked high enough to qualify for the tournament automatically, earned his place by winning in the qualifying pre-tournament, where he was seeded 27th.
