Stan Wawrinka has urged tennis authorities to take a big stick to tennis tyro Nick Kyrgios after the Australian was caught sledging the two-time slam winner.
In a comment picked up by a courtside microphone, Kyrgios, 20, linked the reigning Australian and French Open champion with teenage Australian player, Thanasi Kokkinakis.
“Kokkinakis banged your girlfriend. Sorry to tell you that mate,” said Kyrgios midway through the second set.
Wawrinka divorced his wife Ilham earlier this year and has since been romantically linked with Croatian teenager Donna Vekic.
The world No.5 appeared to not hear the comment at the time but unleashed after the match, won by Kyrgios 6-7 (8-10) 6-3 4-0 after Wawrinka retired with a back injury.
“I just hope the ATP takes big measures against him,” he told reporters in French.
“He’s young but that’s no excuse … every match, he behaves very badly.
“The problem is he doesn’t just behave badly towards himself, he behaves badly towards the people around, the other players, the ball kids, the umpires.
“I really hope the ATP will take major action against him this time.”
Wawrinka said he brought the matter to a head in the changerooms after the match.
“He tried to avoid me but I confronted him,” he said.
“It will stay in the locker room. There are things, regardless of how you are, regardless of the stress you have on the court, there are things you just can’t say.”
Wawrinka’s Swedish coach Magnus Norman weighed in, tweeting: “That was really really low Nick Kyrgios. Hope for u that u have people around that will teach u a thing or 2 about life tonight. Very bad”.
Looking sheepish after the match, Kyrgios told a court-side interviewer Wawrinka “was getting a bit lippy”.
“(It was) kind of in the heat of the moment,” said the Australian.
“I don’t know. I just said it.”
Kyrgios has already drawn the ire of Australian tennis officialdom several times this year.
But Tennis Australia was thrilled that Lleyton Hewitt had agreed to take on a mentoring role with Kyrgios, beginning this week.
Hewitt and Kyrgios were beaten in the first round of the doubles in Montreal.
Kyrgios’ slur also overshadowed a fine day of Australian results.
Compatriot Bernard Tomic and soon-to-be Australian Daria Gavrilova also won through to the last 16 in the Rogers Cup.
Tomic ousted reigning US Open champion Marin Cilic in straight sets.
At the sister event in Toronto, Gavrilova set up a third-round meeting with Roberta Vinci by beating Czech Lucie Safarova in three sets.
Kyrgios said he hoped Wawrinka would overcome his back injuries as he attempts to win a third slam of the year.
“I hope he gets better as soon as possible, obviously US Open around the corner,” Kyrgios said.
Kyrgios will play 16th seed John Isner in the third round in Montreal, while Tomic will play popular Frenchman Jo-Wilfried Tsonga.
