Wawrinka later left the match while 0-4 down in the third set, and took to twitter to complain about Kyrgios’ behaviour.
In his post-match press conference, Wawrinka told reporters that Kyrgios has “big problems”, and that he had confronted Kyrgios in the locker room after the match, and also said he hopes the ATP comes down hard on him.
Posting on twitter @stanwawrinka said :
“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.”
In a court side interview after the match, Kyrgios said :
“You know he was getting a bit lippy at me, so I don’t know it is just in the moment sort of stuff – I don’t really know, I just said it.”
Kyrgios is in Canada warming up for the US Open. This is not the first time that Kyrgios has courted controversy – At Wimbledon, little more than a month ago, he made headlines for arguing with umpires and reporters, and was accused of “tanking”, or giving up on a game, when losing to Richard Gasquet in the fourth round.
Kyrgios has since played for Australias’ Davis Cup team against Kazakhstan in Darwin last month, losing to 115th ranked Aleksandr Nedovyesov.
