Kyrgios apologizes for lewd remark directed at Wawrinka

Nick Kyrgios has apologized to Stan Wawrinka for the remark Kyrgios made about Wawrinka's girlfriend Wednesday during their Rogers Cup match.

Kyrgios wrote on Facebook:

I would like to take this opportunity to apologise for the comments I made during the match last night vs Stan Wawrinka. My comments were made in the heat of the moment and were unacceptable on many levels. In addition to the private apology I've made, I would like to make a public apology as well. I take full responsibility for my actions and regret what happened.

The ATP fined the 20-year-old Thursday. He was defeated 7-5, 6-3 in his third-round match with No. 16 John Isner on Thursday.
