Why Djokovic Is Shirtless And Smiling Mid-Match

Novak Djokovic is at it again.

It may be the quarterfinals of the US Open, but Novak Djokovic still found time to have a laugh.

Tied at two-all in the second set, John Millman stopped the game to have an outfit change, apologising to his opponent for the interruption.

It seemed like a tense moment on court, as Millman explained he "didn't know what to do" because of his excess sweating.

But the Djoker, living up his prankster reputation, was more than happy to let him leave the court.

"I could use a break," Djokovic said.

Making the most of his break, Djokovic took off his shirt, put his hands behind his head and relaxed on the bench.

"I've never seen nothing like this," commentator John McEnroe said.

Djokovic, who had been looking gassed during the second set, was happy to recharge during the extended break.
