The Australian, who capitulated in Sunday's China Open final with Rafael Nadal when incensed by a line call, had already been given a point penalty for an audible obscenity by umpire Fergus Murphy.
The 22-year-old then received a warning for smashing two balls out of court in frustration at another disputed line call before being heard to say that he would quit the match if he lost the first-set tie-break.
Johnson sent down an ace to close out the breaker 7-5 and, true to his word, Kyrgios shook his American opponent’s hand and walked off court to a chorus of boos from the spectators.
The tournament has not been kind to the temperamental youngster and he was fined and banned for his actions at the event 12 months ago and there is every chance of a similar sanction this time around.
The Aussie was forced to undergo psychological counselling at the end of last year as part of a deal to reduce his ban and it remains to be seen what action is taking against the volatile player.
