Most professional men’s tennis matches are played in a best-of-three sets format, with 6 games (and a possible tiebreak) in each set. In Grand Slams (Australian Open, French Open, Wimbledon, and US Open), men play best-of-five sets, which means that players need to win 3 sets to win the match.

When playing, opponents typically compete in a best of three sets match, i.e., the first player who reaches two sets wins the match. However, some men’s professional competitions are contested as best of five sets, which is the maximum used by the sport.
