Nick Kyrgios fined for 'Kokkinakis banged your girlfriend' sledging of Stan Wawrinka
Nick Kyrgios has been fined for an insulting remark made to Stan Wawrinka during their Rogers Cup match in Montreal this week.
French Open champion Wawrinka branded Kyrgios ''unacceptable'' and called for action to be taken against him after the Australian appeared to make comments about his girlfriend.
The ATP confirmed on Thursday: "The ATP has announced that Nick Kyrgios has been fined for an insulting remark made to Stanislas Wawrinka during his second round match against Wawrinka at the Rogers Cup in Canada."
Details of the fine are not being made public until after Kyrgios has been notified.
Kyrgios won Wednesday's contest after the Swiss retired hurt, but it was an apparent exchange at the end of the first set which become the focal point.
On-court microphones recorded 20-year-old Kyrgios walking to the net and saying: ''Kokkinakis banged your girlfriend. Sorry to tell you that mate'' - an apparent reference to Australian Davis Cup team-mate Thanasi Kokkinakis.
Speaking on court afterwards, Kyrgios claimed he had been provoked, saying: ''He was getting a bit lippy with me. Kind of in the heat of the moment, I don't know. I just said it.''
Writing on Twitter, Wawrinka said: ''So disappointing to see a fellow athlete and colleague be so disrespectful in a way I could never even imagine.
''What was said I wouldn't say to my worst enemy. To stoop so low is not only unacceptable but also beyond belief.
''There is no need for this kind of behaviour on or off the court and I hope the governing body of this sport does not stand for this and stands up for the integrity of this sport that we have worked so hard to build.''
Controversy has followed Kyrgios around since his 2014 breakthrough when he knocked Rafael Nadal out of Wimbledon.
At this year's tournament he was moved to deny accusations of abusing an umpire and throwing a game, while on Davis Cup duty with his country he shouted ''I don't want to be here'' while on court.
The woman in question is reported to be 19-year-old Croatian player Donna Vekic, who has been linked to Wawrinka since he divorced his wife Ilham in April.
The 19-year-old was in the crowd to watch the Swiss' Wimbledon third-round win over Fernando Verdasco last month.
Her best performance in a Grand Slam came in 2013, when she reached the third round of the French Open. She partnered Kokkinakis in the mixed doubles at the 2014 Australian Open.
