Daniil Medvedev suffered a complete meltdown during his ATP Tour Finals game against Taylor Fritz.

The Russian tennis star, 28, seemed to lose the plot when he was broken in the second set.

Medvedev would end up losing the match in straight sets 4-6, 3-6.

But it was his antics during the contest that had the crowd puzzled.

While his American opponent Fritz couldn’t help but burst into laughter with what he was seeing.

Clearly frustrated, the world No. 4 repeatedly tossed his racket in the air.

Then, he amusingly turned his racket upside down and tried to return a point.

Medvedev’s bizarre behaviour didn’t put Fritz off – who won comfortably.

After the game, the US Open 스포츠토토사이트 finalist saw the funny side.

“I mean, I was just laughing. I think he’s really funny, to be honest,” Fritz said.

“Even when he’s not playing me, he always cracks me up.

“He’s pretty funny. I was laughing more in between the points when he was, like, tossing the racket up. It’s just him.

“He had the upside down racket, but it’s 40-Love on my serve. It’s whatever. He ended up making the return anyway.”

Medvedev is no stranger to losing his temper during matches.

Back in October, he was seen in an angry exchange with an umpire at the Shanghai Masters.

Medvedev is back in action on November 13, when he faces off against Jannik Sinner
