Stefanos Tsitsipas has explained his lengthy bathroom breaks, insisting he does not take them to disrupt anyone.
Both Andy Murray and Alexander Zverev have directed accusations at the Greek recently saying he times his permitted comfort breaks to ensure his opponents lose momentum and cool down at key stages of matches.
Tsitsipas, though, has dismissed those allegations, saying he simply goes off to change his clothes and 'freshen up' within the rules of the game, and so he does not believe the criticism is fair.
"It is important to take it if you have to," Tsitsipas explained.
"First of all, you carry less weight on you with all the sweat. You feel rejuvenated, you feel fresh, and you don't have all the sweat bothering you and coming in your face, on your fingers, and everywhere all over your body. It makes you feel better.
"For me, it is important to take that break. For someone else probably not. And everyone has his own time.
"I try and be as quick as I can. Sometimes I just need a bit more time. That's all.
"If I break a rule, then sure I'm guilty. If I'm staying within the guidelines, what's the issue?"
"It's my personal need. Some players take, as we know, much more than 25 seconds between points which is fair.
"I don't have anything against any player and I never complain about what other players do.
"Since I was a young kid my parents have taught me not to watch other people's business and concentrate on myself and do my job.
"I just don't understand why other players go and criticize other players during a match. They put too much emphasis on it."
During his US Open first round win over Murray, Tsitsipas took two long breaks just before Murray was due to serve. In his second round match, he took another long break after dropping a set to Adrian Mannarino.
