ATP fines Kyrgios for 'insulting remark' toward Wawrinka

MONTREAL (AP) — The ATP has fined Nick Kyrgios 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 Thursday 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."

The ATP rule book allows a fine of up to $10,000 for incidents of verbal abuse or unsportsmanlike conduct.
