Nick Kyrgios and Stefanos Tsitsipas have both been hit with fines for their conduct in their ill-tempered clash at Wimbledon on Saturday.
Kyrgios claimed a 6-7 (2-7) 6-4 6-3 7-6 (9-7) victory over the World No.5 in their third-round clash that was littered with controversy.
At one stage at the end of the second set, Kyrgios demanded Tsitsipas be defaulted after the Greek star angrily whacked a ball into the crowd.
Tsitsipas was lucky to be allowed to continue because the ball didn't appear to hit anyone, but Kyrgios labelled the umpire a 'disgrace' for his leniency.
Both men copped code violations throughout the match, while Tsitsipas was hit with a point penalty when he thundered a ball into a scoreboard that he later admitted he was aiming at Kyrgios.
On Sunday, Wimbledon organisers revealed that Tsitsipas was fined $US10,000 ($A14,700) for hitting the ball which narrowly missed spectators.
Kyrgios, who'd already received the same punishment after spitting in his first-round match, was slugged a further $US4,000 ($A6,000) for his histrionics.
Speaking in his post-match press conference, Kyrgios said he wanted to see Tsitsipas punished for his actions.
“I always get fined, so I’m very keen to see what he will get after today,” the Aussie said.
The Australian hot-head threatened a sit-down protest after Tsitsipas only received a code violation for back-handing a ball in frustration into the stands.
"You can't hit a ball into a crowd and hit someone and not be defaulted," Kyrgios bellowed at chair umpire Damien Dumusois, while pointing out to that Novak Djokovic was booted out of the US Open in 2020 for striking a line judge with a ball.
"I would like to speak a supervisor. I'm not playing until I speak to a supervisor."
"Bring out more supervisors. I'm not done. Bring them all out."
Pat Cash levels 'cheating' allegations at Kyrgios
In a staggering twist to the saga on Sunday, Aussie great Pat Cash claimed some of Kyrgios' actions amounted to cheating.
With Kyrgios given his first centre-court date of the championships on Monday in a fourth-round clash with American Brandon Nakashima, Cash said pointedly: "Let's hope he doesn't drop tennis there to a lower level than he did on Saturday."
"It was absolute mayhem," he said on BBC radio.
"He's brought tennis to the lowest level I can see as far as gamesmanship, cheating, manipulation, abuse, aggressive behaviour to umpires, to linesmen.
"He was lucky to even get through the first set, he should have been defaulted in the first set.
"Something's got to be done about it - it's just an absolute circus. Is it entertaining? Yeah, possibly. It's gone to the absolute limit now."
Pressed on the cheating claims, Cash added: "The gamesmanship. The abuse he was giving.
"Tsitsipas would make a line call and he'd go up there and start complaining, he'd be in his face - that's part of gamesmanship, that's the sort of stuff he does and I think there's a limit.
"I have no problems with a bit of gamesmanship but, when it gets to that level, I think it's just out of control.
"As it was, the umpire lost control. The ball kids were running across the court as Kyrgios was serving, he didn't slow down for any of that stuff.
"Tsitsipas got sucked right into it - so it was entertaining and fascinating, but for me it's gone too far now."
