'You don't need to do that': Nick Kyrgios launches into chair umpire as Thanasi Kokkinakis hit with code violation

Nick Kyrgios was left fuming with the chair umpire during his doubles clash after Thanasi Kokkinakis was hit with a violation for ball abuse.

Up against James Duckworth and Alexsandar Vukic, all four Aussies were engaged in a tense rally at 4-3 with Duckworth and Vukic looking to break the serve of their rivals.

Kokkikankis lost the point by hitting the ball into the net and then aggressively hit the ball into the air on the rebound.

Under the player code of conduct, Kokkikankis' act breached the rule that states 'players shall not violently, dangerously or with anger hit, kick or throw a tennis ball within the precinct except in the reasonable pursuit of a point during a match'.

As the umpire handed down the violation, Kyrgios fired up.

"Bro, really? Really? You're really going to do that?," he said immediately.

Kyrgios then made reference to the fact Kokkinakis was playing injured after struggling to get through his singles match the night before.

"So him trying to play in front of the fans doesn't mean anything? You're going to give him a f---ing code violation for that? Really bro? F--k off."

Kyrgios' rant didn't stop when he murmured to himself "bro, read the game" before mentioning the code violation again.

Kokkinakis and Kyrgios then won the next game to make it 5-4 and Kyrgios had eyes only for the umpire once they sat down.

He unloaded again.

"We're both injured right, full stadium of people to come see us play and he (Kokkinakis) doesn't have to be here right and he hits a ball out of pain and you're going to give him a code violation," Kyrgios said.

"But it's not unsportsmanlike? I'm just saying, read the game a bit more.

"I'm just saying, you don't need to do that."

Kokkinakis was then heard accusing Jack Draper, his singles opponent from the second round, of committing the same act but hitting it flat.

Eventually, Kokkinakis and Kyrgios succumbed to injury during the doubles clash, retiring with Duckworth and Vukic leading 7-5, 3-2.
