If Novak Djokovic is to employ his toilet tactic against Jannik Sinner at Wimbledon, he’ll have to do it quickly.Rule changes have recently been introduced in tennis to limit bathroom time during matches, with the Serbian legend one of many to use them to his advantage.Djokovic was two sets down and heading out against Sinner in 2022GettyBut after a lengthy toilet break the legend was rebornAFPHowever, back in 2022 it wasn’t to delay or get in Sinner’s head, but in fact to provoke himself.Djokovic and Sinner face off again at Wimbledon in the semi-finals of the men’s tournament, and their first such encounter three years ago saw the senior Serb go missing for a solid number of minutes while two sets down.He rallied back to an almighty comeback over his Italian opponent and would then beat Nick Kyrgios in the final for his seventh Wimbledon title and 21st of a record 24 Grand Slams.But after downing Sinner, he admitted his disappearance was spent in the SW19 loos.“He was the better player for the first two sets but I had a toilet break and a pep talk in the mirror,” Djokovic revealed post-victory.“It’s true – sometimes these things are necessary. The toilet break was the turning point.“I go through the same doubtful moments as anyone else. The inner fight is the biggest fight you go through.”A number of viewers fumed on social media, agreeing that the toilet break was the turning point, but arguing that it shouldn’t be allowed.In fact, so known was Djokovic’s toilet tactic that the Wall Street Journal conducted a statistical analysis claiming he’s won 78.6 per cent of the sets following a toilet break.With the narrative becoming increasingly popular, fans have since got their own way with the ATP introducing a rule to cut them out.Djokovic said in his post-match interview that the toilet break played its partGettyThere was also the flashpoint of Sinner rolling his ankleAFPToilet breaks are now only permitted once per match, limited to three minutes, and can only take place at the end of a set.That means that if Sinner goes two sets up again, Djokovic will have to come up with a different kind of mastery.Yet even with his high profile admission in ‘22, the now 38-year-old has been outperformed when it comes to toilet breaks by quite an extent.Former world No.3 Stefanos Tsitsipas conducted by far the most egregious use and it left British legend Andy Murry flipping his lid.The Greek was at his best in 2021 making two Slam finals in Australia and France, but he used his biggest mind games in the first round against Murray in the US.Tsitsipas took numerous breaks throughout his five-set win, including a medical timeout for treatment on his foot.View Tweet: https://twitter.com/hashtag/USOpen?src=hash&ref_src=twsrc%5EtfwYet it was the final eight-minute toilet break in the deciding set that successfully caused Murray to lose it.“What for 20 minutes every time?” he angrily asked the match supervisor. “How long do you think it was, and the toilet’s right there.“What’s he doing in there? It’s never once taken me that long to go to the toilet ever and it’s right there.”Murray also told the umpire his opponent was ‘cheating’ and then added post-defeat: “It’s not so much leaving the court, it’s the amount of time.“It’s disappointing because I feel it influenced the outcome of the match.“I’m not saying I necessarily win that match but it had an influence on what was happening after those breaks.Murray fumed at the umpire and supervisor, but in the end he lostGetty“I rate him a lot. I think he’s a brilliant player. I think he’s great for the game. But I have zero time for stuff like that at all, and I lost respect for him. I think it’s nonsense, and it he knows it as well.”So high profile was the drama that it provoked the ATP’s change, an outcome that Djokovic is now the victim of.
