MONTREAL — The ATP fined Nick Kyrgios on Thursday for his "insulting remark" toward French Open champion Stan Wawrinka during a match at the Rogers Cup.
The organization did not announce the amount of the fine but said in a statement that further details would be released after Kyrgios was notified. Wawrinka had urged tennis authorities to take action in a Twitter post earlier Thursday.
On Wednesday night, a courtside microphone picked up Kyrgios saying that fellow Australian player Thanasi Kokkinakis had slept with a player who is reportedly Wawrinka's girlfriend.
Wawrinka later tweeted: "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.
