Tennis is a sport which is not time-bound. But usually, we don’t see a match going on more than 2 -3 hours. But it takes a high amount of grit & stamina from a player’s body when the game lasts for long hours.
Although, Introduction of the tiebreak in 1970 reduced the chances for long matches in tennis. All Grand slams then used tie-breakers but not The French Open, which used the advantage set rules.
But most Tennis fans have witnessed the longest match in tennis history which happened in the first round of Wimbledon in 2010 and lasted for 11 hours 5 minutes. Interestingly four of the top 5 encounters were played between 2010-18.
Here is a list of all-time longest matches in Tennis history
