The ATP will limit stops in the middle of games to go to the bathroom, with a maximum of three minutes per excursion and only one trip allowed per game.
This new regulation arises in response to the controversies that arose this season, when Novak Djokovic went to the bathroom for several minutes when he lost at Roland Garros against Lorenzo Musetti and Stefanos Tsitsipas, by two sets to zero, and also when the Greek did it in the first round of the US Open.
That was the final tense point, with Tsitsipas going to the bathroom at the beginning of the fifth set against Andy Murray and staying there for eight minutes, which raised the complaints of the Briton, who ended up telling the Greek that he had lost respect for him.
Now the ATP will limit trips to the bathroom to one per game, of no more than three minutes. You can only go to the toilet at the end of a set, while an extra two-minute trip will be allowed in case it is to change clothes.
