Nick Kyrgios Denies Stan Wawrinka's Accusation He Never Apologized for Insult

The war of words between Stan Wawrinka and Nick Kyrgios continued Thursday after Kyrgios refuted Wawrinka's claims that the Australian tennis player didn't apologize for inappropriate remarks made at a match last week regarding Wawrinka's girlfriend. 

"No, he didn't apologize, so no," Wawrinka said during a post-match interview at the Western and Southern Open, according to the Sydney Morning Herald's Michael Chammas. "But I prefer not to talk about him. Thank you."

Kyrgios replied with a Facebook post insisting that he has apologized to the fifth-ranked player in the world: 

"

I am not trying to take any more attention away from the matches in Cincy, but I have been reading reports that I did not apologise for my comments, which is untrue. I privately and publicly apologised immediately after the match last week. There is no blame game, I take full responsibility for what was said and for what has been a difficult learning experience. ‪#‎NKRising

The public apology Kyrgios alluded to came via a Facebook post on Aug. 13, when he relayed the following message:       

"

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. 

"

Following the incident, the ATP slapped Kyrgios with a maximum fine of $10,000, according to the Associated Press (via the New York Times).     

While Wawrinka is still frustrated with Kyrgios' actions, he stood tall and withstood a first-set loss against Ivo Karlovic on Thursday to take the round-of-16 clash and advance to the Western and Southern Open quarterfinals. All three sets resulted in 7-6 tallies, with Wawrinka taking the final two. 

Kyrgios, meanwhile, was dropped in the first round of the Western and Southern Open by Richard Gasquet.

Wawrinka will now look to put the controversy behind him as he seeks to build solid momentum with the U.S. Open on the horizon.
