Williams was given a 3rd code violation in the 2nd set of the U.S. Open Final, resulting in the loss of a game. Naomi Osaka would go on to with the match in straight sets 6-2, 6-4.

Williams clashed with chair umpire Carlos Ramos, demanding an apology after he initially issued a warning for a code violation in the second set's second game for receiving coaching, which is not allowed during Grand Slam matches.

King tweeted, "when a woman is emotional, she's 'hysterical' and she's penalized for it ." King wrote that if a male player had a similar outburst, he'd be called "outspoken" and have no repercussions.

King also tweeted that coaching should be allowed in tennis.
