Serena Williams has been fined a total of US $17,000 (NZ$25,700) after her outburst during yesterday's US Open final defeat to Naomi Osak.
Williams, 36, was given three separate code violations during the second set of yesterday's loss in New York, resulting in Osaka being awarded a game as a penalty.
The fine breaks down to being US$10,000 for verbally abusing chair umpire Carlos Ramos, including calling him a thief, a further US$4,000 for being warned for coaching, and US$3,000 for breaking her racket.
Williams then unleashed a furious outburst towards the match officials, delaying play for several minutes.
"To lose a game for saying that is not fair," Williams said post match. "There's a lot of men out here that have said a lot of things and because they are men that doesn't happen."
This was the third high-profile conflict with an official for Williams at Flushing Meadows, following her infamous tirade after a foot fault in the 2009 semifinals against Kim Clijsters, and a dispute over a hindrance call in the 2011 final against Sam Stosur.
