Kyrgios wins heated showdown | Tsitsipas: He's a bully!

Nick Kyrgios knocked out fourth seed Stefanos Tsitsipas in a dramatic and

controversial showdown on a raucous No 1 Court on Saturday night.

The maverick Australian recovered from losing a first-set tie-break to win 6-7 (2-7) 6-4 6-3 7-6 (9-7) to win a match featuring code violations, a point penalty and numerous rows with officials.

At one point Kyrgios even demanded his opponent be defaulted for smashing a ball into the crowd in a bad-tempered affair.

Tsitsipas accused Kyrgios of being a bully and possessing an "evil side" in his post-match press conference.

He said: "It's constant bullying, that's what he does. He bullies the opponents. He was probably a bully at school himself. I don't like bullies. I don't like people that put other people down.

"He has some good traits in his character, as well. But he also has a very evil side to him, which if it's exposed, it can really do a lot of harm and bad to the people around him."

"I'm not sure how I bullied him. He was the one hitting balls at me, he was the one that hit a spectator, he was the one that smacked it out of the stadium," said Kyrgios.

"I just don't understand what I did. Like I did nothing towards him. I didn't think I was aggressive towards him.

"I wasn't hitting balls at his face. I don't know. I didn't feel like there was any anger.

"I had no anger towards Stef today on the match. I don't know where it's coming from, to be honest.

"If he's affected by that today, then that's what's holding him back. I just think it's soft."

A chaotic encounter began in relative calm with Kyrgios putting in a near-flawless display of serving - including an under-armer between the legs - in the first set.

Kyrgios had dropped just four points behind his serve, only to lose
