The longest match in tennis history happened during the 2010 Wimbledon Championships and took three whole days to complete.
The “endless match” took place on June 22nd, and started out like any other. It was day two of the first-round matches at Wimbledon and American John Isner was facing off against Frenchman Nico Mahut. Neither tennis player was a household name so most viewers didn’t give the match any thought.
As with every men’s grand Slam match, the winner is decided by best of five sets, and the two opponents split the first four sets, forcing a fifth to decide the winner. But because additional tiebreakers were needed to decide the prior two sets, the match was postponed due to darkness.
While a tiebreaker can be used to decide who wins the match, the set itself has two be won by two games if it reaches a tiebreaker — which it did. So, while Isner and Mahut played it out, each trying to get two consecutive games over the other, they managed to set the record for the longest match in tennis history — and they were just getting started.
The match went on throughout the second day, until it finally had to be delayed again because of darkness. Isner was finally able to win the match on the third day after only one hour. In total, the match took 11 hours and five minutes.
