Serena Williams insisted she was not cheating in the US Open final on Saturday before accusing the sport which has made her a global icon of sexism. Naomi Osaka won the final 6-2, 6-4 to become Japan's first ever Grand Slam singles champion. It also delayed Williams's bid for a record-equalling 24th major title. However, the final was overshadowed by the American's angry and tear-filled meltdown in the second set.
She was handed a code violation for coaching, a penalty point for racquet abuse and a game penalty for calling umpire Carlos Ramos a "liar and a thief" and insisting "you owe me an apology".
Williams insisted that her coach Patrick Mouratoglou had not been coaching her even though the Frenchman told ESPN that he had and that all coaches do it.
"I just texted Patrick, like, What is he talking about? Because we don't have signals. We have never discussed signals," said Williams.
"I've seen other men call other umpires several things. I'm here fighting for women's rights and for women's equality," said the 36-year-old.
"For me to say 'thief' and for him to take a game, it made me feel like it was a sexist remark.
"He's never taken a game from a man because they said 'thief'. For me it blows my mind. But I'm going to continue to fight for women."
Williams made reference to the incident last week when French player Alize Cornet was warned for removing her shirt on court.
