Denis Shapovalov claims he`s got the smallest bladder on tour and the Canadian was not impressed when an umpire at the Australian Open denied his request for a toilet break. The world number 11 had dropped the fourth set of a five-set epic against Italian teenager Jannik Sinner that finished in the early hours of Tuesday and desperately needed to relieve himself. 

"What happens if I go?" asked the 21-year-old, "Do I get a fine? I don`t care!" he ranted at German umpire Nico Helwerth, who turned down his request. "What do you mean, I can`t go? Are you going to disqualify me? I have to pee!" He stepped up his tirade when it became clear the umpire would not relent. "I`m going to piss my pants!" he said. "I`m going to piss in a bottle."
