Serena Williams has been fined £17,000 after receiving three code violations during Saturday's US Open final, in which the American accused the match umpire of lying and tearfully remonstrated with officials before going on to lose in straight sets to Naomi Osaka.
Williams was furious when she was given a coaching violation early in the second set after a hand gesture from her coach Patrick Mouratoglou, before telling umpire Carlos Ramos she would rather lose than cheat.
She was then docked a point for a second violation when she smashed her racket. Continuing her argument with Ramos at the next change of ends, Williams accused him of being a thief for taking a point away from her.
Ramos gave her a third violation, which resulted in a game penalty, putting Osaka 5-3 ahead. A tearful Williams argued her case with tournament officials but, although she held serve in the next game, Osaka served out the victory 6-2 6-4.
Mouratoglou later admitted he had been coaching, but Williams insisted they had never discussed such communication.
Mouratoglou alleged Osaka's coach Sascaha Bajin was also coaching, and it is an open secret that such conduct is commonplace.
