She got into a heated row with umpire Carlos Ramos, after resenting a violation for being coached which her coach later admitted before accusing him of treating her differently to male players.
Williams spoke exclusively to The Project's Lisa Wilkinson, in an interview to air next Sunday.
The International Tennis Federation supported Ramos in a statement released Monday, saying that his decisions were "in accordance with the relevant rules and were re-affirmed by the US Open's decision to fine Serena Williams for the three offenses".
Male tennis players are nearly three times more likely to be fined for losing their temper and smashing racquets than their female counterparts, The New York Times reported on Saturday. "It's because I am a woman, and that's not right". I didn't get coaching...
"I saw how Serena was being treated, and then I thought about coming back to my locker one day as a player, and there was [a reporter] in my chair", said Aaron, who endured racist taunts and death threats as he marched toward Babe Ruth's record. "But I was like 100 percent of the coaches on [sic] 100 percent of the matches", Mouratoglou told ESPN.
Osaka moved at the age of three with her family to the United States where she now resides in Florida and trains there.
USA player Steve Johnson added: "Look, I don't want this to come out the wrong way, but he enforced rules that have been enforced on me over the years". How can you say that? This latest crop of players all seem too entitled, that's a problem I suffer within all walks of life, young people feeling as though they are owed something.
Seeing this, Serena furiously called the umpire "a thief", causing him to list that as the third offence, "verbal abuse". He did what he had to do in that match, because she overstepped the limit. It was about seeing one of the most extraordinary female athletes who has ever lived continuing to be great even after delivering a baby and long past the time when somebody in her profession would ever reasonably be expected to be in the finals of a major tournament.
I hate to sound whiny, but Serena's incident, whether you think she is a sore loser or not, should bring us to think about how we treat women who are not conventionally "ladylike". Say it. Say you're sorry. Calling Ramos a "thief" and a "liar" explicitly violates that rule, and Ramos let Williams vent for quite some time before finally imposing the penalty.
Despite being vaulted into stardom on the world stage, the Japanese No.1 told reporters after her victory that she intends to remain grounded headed into the Asian swing - where her next tournament will be on home soil in Tokyo.
