Serena Williams has been fined US$17,000 for three code violations during her US Open final defeat to Naomi Osaka - including her angry outburst towards the umpire.
Williams was enraged by Carlos Ramos's warning for receiving coaching from her box, and accused him of being a "thief".
She had received a second code violation for racquet abuse along with a point penalty when she lost her temper and was given a third penalty point.
"You're attacking my character," she said. "You will never, ever be on another court of mine. You are the liar."
The tournament referee's office docked Williams $10,000 for the "verbal abuse", $4,000 for being warned for coaching, and $3,000 for breaking her racket, Associated Press reported.
The money comes out of her prize money of $1.85 million as the runner-up.
