Serena Williams has been fined $17,000 for her conduct during Saturday's US Open final defeat to Naomi Osaka.
Williams was issued a code violation for what umpire Carlos Ramos deemed to be coaching from Patrick Mouratoglou, irritating the 23-time major champion who insisted she was not a cheat.
A point penalty for racquet abuse led to her branding Ramos a "liar" and a "thief" and she was then docked a game, after which she called for the match referee and alleged she was being treated differently to male players.

Williams was in tears as she saw out a 6-2 6-4 loss to Osaka, whose maiden grand slam triumph was overshadowed by her opponent's argument with the official.
The American's behaviour has divided opinion, with Billie Jean King among the high-profile figures to come out in support of Williams in the face of fierce criticism from some quarters.
