Nick Kyrgios is facing investigation from the governing body of men's tennis and increasing criticism across the sport's spectrum.
Witness: The head of women's tennis and legendary player Martina Navratilova this week called for strong punishment of Kyrgios for his sexually-oriented comments about a female player's relationships.
On Wednesday, Kygrios was caught on camera twice making derogatory comments regarding Stan Wawrinka's relationship with Donna Vekic.
Kyrgios was fined $10,000 for one comment regarding Vekic's previous relationship with Thanasi Kokkinakis. He was fined $2,500 for a second comment about Wawrinka and Vekic. And the Association of Tennis Professionals, which governs men's tennis, said it would weigh additional punishment.
Kyrgios, 20, has a history of hot-headed reactions on the court and is seen by tennis observers as the current "bad boy" in the sport. Wawrinka, 30, is in a relationship with Vekic, 19. He is from Switzerland; she is from Croatia.
Kyrgios, who is No. 41 in ATP rankings, has issued apologies to all three in statements released by his management.
Now, the Women's Tennis Association enters the fray.
"The statement made by Nick Kyrgios is crude and unacceptable," WTA Tour director Stacey Allaster said in a statement.
"I commend the ATP on assessing the on-site maximum fine and urge there to be further sanctions in accordance with their process."
Navratilova offered this comment via Twitter: "I think there needs to be more than just a fine. There is no place for that kind of behavior, that is clear."
Kyrgios won his match against Wawrinka, who withdrew because of back pain, only to lose his next match at the Rogers Cup tournament in Montreal. He was lustily booed when he entered the court on Thursday and as he left in defeat.
Asked about additional punishment, Kyrgios said: "No, I don't think there should be. It's all clear now. I apologised in public and privately as well. I have been fined so everything has sort of been put to bed now and I feel we can move on from it."
The ATP Player Council condemned Kyrgios.
"Comments like these have no place in our sport and have been met with endless criticism from the larger player body," according to a statement the group released.
"Nick's comments were disrespectful not only to Stan, but to the other players referenced. We understand sometimes things are said mistakenly under tense circumstances, but Nick's comments are indefensible.
"We fully support the ATP in their fining of Kyrgios and anxiously await for further repercussions for him once a more complete investigation has been done."
Kyrgios does have defenders albeit not of his comments. Britain's Andy Murray told the BBC: "People need to give him a little bit of a break." He did not, however, condone Kyrgios' actions.
"In other sports that sort of thing gets said more often than we imagine and in team sports especially," Murray said. "In tennis there are certain things you shouldn't do and that was one of them.
"Hopefully he learns from it. Nick is not all bad, he is a young guy growing up in the spotlight. There has been a lot of negativity towards him over the last few months and that isn't easy to deal with."
Australia's Davis Cup captain says Kyrgios remains in his plans.
"We're looking at a young kid, he's got enormous potential, he's a good kid at heart," Wally Masur told Fox Sports.
"We're trying to put things in place behind the scenes that can make a difference and help Nick achieve that potential.
"Nick is on a journey, this is all part of a learning curve."
