Tennis has been one of the most popular sports in the world for centuries. The game is played in nearly all regions of the earth and in many cases has been passed down from generation to generation. With the increase of popularity comes the increase in competition. There is no denying how competitive and tight these matches go.
Tennis matches can be played in various formats, including singles and doubles. Singles matches typically involve two players, while doubles matches have four players (two on each team). Doubles matches often result in longer rallies and, consequently, longer games. In Grand Slam tournaments like Wimbledon, the US Open, the Australian Open, and the French Open, matches can potentially be longer. These tournaments employ a best-of-five-sets format for men's singles and doubles matches. Consequently, some men's Grand Slam matches have been known to extend well beyond four hours. Here are the five longest tennis matches ever seen on the professional tour.
