Serena Williams has been fined a total of £13,000 ($17,000) for three code violations during the US Open final.
The tournament referee's office docked Williams £7,800 ($10,000) for 'verbal abuse' of chair umpire Carlos Ramos, £3,100 ($4,000) for being warned for coaching, and £2,300 ($3,000) for breaking her racket.
The money comes out of her prize money of £1.4million ($1.85m) as the runner-up.
Williams' furious outburst at umpire Carlos Ramos overshadowed her 6-2 6-4 final defeat by Naomi Osaka at Flushing Meadows on Saturday.
Initially unhappy about being penalised for Patrick Mouratoglou coaching from from the stands, Williams was then given a point penalty for smashing her racket before Ramos took a game away from her after she called him a 'thief'.
The American tennis great stated afterwards that it was 'sexist' for her to have been penalised a game.
During her post-match press conference, the 36-year-old said: 'I can't sit here and say I wouldn't say he's a thief, because I thought he took a game from me.
'But I've seen other men call other umpires several things. I'm here fighting for women's rights and for women's equality and for all kinds of stuff.
'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'. It blows my mind.
'I just feel like the fact that I have to go through this is just an example for the next person that has emotions, and that wants to express themselves, and wants to be a strong woman.
'They're going to be allowed to do that because of today. Maybe it didn't work out for me, but it's going to work out for the next person.'
Saturday's rant was not the first on-court outburst of Serena's career. She clashed with umpire Mariana Alves during a 2004 US Open quarter-final against Jennifer Capriati.
Five years later at Flushing Meadows she threatened to shove a tennis ball down the throat of a line judge who called a foot fault against her. She was fined a record 82,500 dollars (£51,000) and put on a two-year probation.
Another fine was dished out at the 2011 US Open after Williams berated umpire Eva Asderaki, who had awarded a point against the American because she shouted 'Come on' mid-rally. Williams was furious and harangued Asderaki, calling the umpire 'a hater' and saying she was 'unattractive inside'. She was fined only $2,000 (£1,250).
Tennis legend Billie Jean King, who won 12 Grand Slam singles titles, including four US Opens, was among those who jumped to back Williams as the row escalated.
King said on Twitter: 'Several things went very wrong during the Women's Finals today.
'Coaching on every point should be allowed in tennis. It isn't, and as a result, a player was penalized for the actions of her coach. This should not happen.'
