Kyrgios is no stranger to controversy and he made headlines for all the wrong reasons last night when he repeatedly abused umpire Fergus Murphy during his second-round clash with Karen Khachanov.
The Australian won the first set in a tiebreak but he grew frustrated with Murphy, accusing him of starting the 25-second shot clock too early.
At the end of the second set tiebreak, Kyrgios was then issued a point penalty after using an expletive.
He then left the court for a bathroom break and television pictures showed him smashing two rackets in a tunnel before walking back onto court.
Kyrgios would go on to lose the match 6-7, 7-6, 6-2 and after embracing Khachanov at the net, he appeared to spit towards the official’s chair and did not shake Murphy’s hand.
This evening, the ATP issued a hefty fine of $113,000 to Kyrgios and said he was still under investigation, which could lead to an additional fine and/or suspension.
In reaction to the news, Petchey was asked for his assessment and he launched a defence of Kyrgios using punishments handed to Serena Williams to make his point as he questioned the fine.
“He’s been fined $113,000. It is an awful lot of money,” he said on Amazon Prime.
“Lets go back to Serena Williams at the US Open last year and the negative press that generated.
“She had prior at the US Open from 2009 and only an $82,500 fine there. That was reduced on good behaviour.
“Nick hasn’t been given that opportunity. And of course, Serena fined only $17,000.
“So you do have to question whether Nick is getting punished consistently in respect to everyone else out there.”
The incidents involving Williams which Petchey is referring to are from last September when Williams was fined $17,000 for calling umpire Carlos Ramos a “liar” and “thief” during the US Open final following perceived coaching.
And in 2009, Williams argued with a line judge over a foot fault call and was fined $82,500.
Kyrgios will now head to New York for the US Open with doubts over whether he will be allowed to participate after his latest indiscretion.
