Having been docked a point for an audible obscenity during the tie-break, he told Murphy that he would walk off court if he went on to lose the set, and he was as good as his word.
Temperamental Australian Nick Kyrgios was fined $A12,840 and lost another $A27,071 in prize money on Wednesday after storming off midway through his first-round match in Shanghai, tennis officials said.
The 22-year-old, who later claimed he was suffering from a stomach bug, was booed by the crowd as he walked off the court.
And when he was hit with a point penalty, Kyrgios said: "Poor officiating again. He can go in a spiral and get in the doldrums and then it takes quite a lot to lift him", said Croft. "He then needs other people around him and the right advice that he can respond to and lift his spirits a little bit".
"You think this place could not get any more ridiculous, sh*t like this happens".
He wrote: "Guys I want to apologise to the fans in Shanghai and those that watched around the world on TV today".
The Evil Within 2 | Launch Trailer
In an action-packed trailer Sebastian, the protagonist for The Evil Within 2 is stepping into a living haunted house with enough monsters and nightmares to make anyone think twice.
"My shoulder started to hurt in the practice today which didn't help either and once I loss the first set I was just not strong enough to continue because I've not eaten much the past 24 hours". The tweet later appeared to have been deleted from his account.
He had earlier received a warning for smashing two balls out of court in frustration at a line call. According to ATP Tour rules, it is mandatory to be examined by a physician if injured. Subsequently, Kyrgios was fined and slapped with an eight-week suspension by the ATP.
Kyrgios also earned almost $11,500 USA for reaching the second round of doubles.
It's the second year in a row the hot-headed Aussie has been punished for bad behavior at the Shanghai Rolex Masters.
Only previous year, he was fined $21,200 and hit with an eight-week suspension for tanking against Mischa Zverev in the second round of the same tournament. Big deal. I don't owe them anything.
Kyrgios won that match, eventually going on to compete against Rafael Nadal in the final.
