BBC Sport tennis. The rules of scoring. The maximum number of sets in a match is five for men and three for women. Usually the first player to win six games wins a set but if the score becomes five-games-all, one player must be two games ahead to win the set. So a player must win the set 7-5 or 8-6 or 9-7 and so on.
On June 24, John Isner and Nicolas Mahut finally finished the longest match in tennis history. Their match lasted three days and over 11 hours. The first four sets looked like any typical tennis match, but the fifth set put this game in the record books. Isner finally beat Mahut 70-68. This match made me think about the longest games in sports history and where Isner vs. Mahut stands in the record books.
