Strict new guidelines on toilet breaks during matches have been sent to players by the ATP after growing calls to make lengthy visits to the bathroom a thing of the past.

The ATP guidelines will limit bathroom breaks to one per match, lasting no longer than three minutes. Players on the ATP and women’s WTA tours have regularly been accused of using bathroom breaks as tactical weapons at crucial junctures in matches.

Stefanos Tsitsipas was accused of cheating at this year’s US Open by Andy Murray after the Greek disappeared off court at various times during their marathon first-round match. In his next match, Tsitsipas went to the locker room for more than seven minutes after losing the third set, and was jeered by the Arthur Ashe Stadium crowd on his return.

Tsitsipas argued that he was not breaking any rules, which is why the ATP has decided to act.

Although toilet breaks will be limited to three minutes, players will also be allowed two minutes to change their clothing. Players will be limited to one toilet break per match and they will only be permitted at the end of a set.

Should a player spend too long in the bathroom he will be liable to time violations.
