Serena Williams has been fined $17,000 by the US Tennis Association for three code violations during her US Open Final match with Naomi Osaka.
Williams who lost the final game to the 20-year Osaka, had gotten into a heated argument with the umpire Carlos Ramos, calling him a liar and a cheat for penalising her over alleged coaching.
Serena was also penalised for breaking her racket in anger and for accusing Ramos of sexism.
The US Tennis Association has now fined Williams $10,000 for “verbal abuse” of Ramos, $4,000 for being warned for coaching and $3,000 for breaking her racket.
This fine will come out of her prize money of $1.85 million as the runner-up.
Naomi became the first Japanese and first Haitian to win a grand slam title.
