This was agreed by the Grand Slam Board, in which the major tournaments Australian Open, Roland Garros, Wimbledon and US Open are represented. The decision will then be made in the third (women) or fifth set (men) with a score of 6: 6 in a ten-point tie-break. The tennis player who first has ten points in the tie-break – by two points – is then the winner of the game. So far there have been different regulations in all four Grand Slam tournaments.
More than eleven hours of gameplay
In the past, there have always been marathon matches at the Grand Slam tournaments, especially for men. The duel between John Isner and Nicolas Mahut at Wimbledon in 2010 has become legendary. Isner won the fifth set 70:68. With more than eleven hours of play, this duel is the longest match in tennis history.
The new rule will be applied for the first time at the French Open (May 22 to June 5). So far there has been no tie-break in Paris in the decisive set.
