Williams was incensed at the coaching violation, although coach Patrick Mouratoglou, sitting in her box, admitted that he was coaching when he moved his hands.
US Open champion Naomi Osaka grew up dreaming of competing against Serena Williams in a Grand Slam final but never would have dared to go as far as to think her idol would be reduced to tears in a drama-filled match.
Williams, beaten by Naomi Osaka, was docked a game for verbal abuse and had a point penalty for racquet smashing and a code violation for coaching.
Williams, who in the end could not make sports history and match the record of 24 Grand Slam titles held by Margaret Court, did it negatively as she was the only tennis player to lose three times in Flushing Meadows, after the semifinal of 2009 and the end of 2011.
Williams smashed the racquet after Osaka broke her serve to take a 3-2 lead, which is automatically a point penalty. "But then when I hugged her at the net.", Osaka explained as she began to tear up. I just feel like I had a lot of emotions, so I had to kind of categorize what was which emotion', Osaka said.
King tweeted, "when a woman is emotional, she's "hysterical" and she's penalised for it".
"What the umpire did is totally not acceptable and I hope that we are going to have a sanction because we just can't let that happen", she said. She was telling me to think of it as just another match and then I would yell at her, 'Are you insane?
"I couldn't eat anything, I felt like I was going to throw up".
Williams was standing on the same side of the court - to the right of the umpire's chair - from where she famously lost her temper twice before. First, he said everyone gets coaching, which is widely known in professional tennis, even if Grand Slam rules forbid it.
A few games later, Williams slammed her racquet and broke it. There's also the freakish "abuse" citation, which Ramos doled out because Williams called him a "thief" - certainly far from the worst thing an athlete has called an official during an event.
Osaka ahead 15-love, Williams told Ramos he should have retracted the initial warning for coaching.
The jeers were not aimed at her, with the fans instead expressing a sense of injustice at the way home favourite Williams had been treated.
Briefly, Williams appeared to be working her way back into the match, breaking Osaka for the only time to go up 3-1 in the second set.
"This is outrageous", said Williams warming to her theme. "Unusual to do that in a Grand Slam final", Mouratoglou said. "He's never took a game from a man because they said thief".
Verbal abuse is defined as a statement about an official, opponent, sponsor, spectator or other person that implies dishonesty or is derogatory, insulting or otherwise. But I've seen other men call other umpires several things.
"Like 100 per cent of the coaches, in 100 per cent of the matches, so we have to stop this hypocrite thing", he said.
"It's weird in the women's game where they have coaching", said Barker. "Maybe there has to be a supervisor that comes on and has the final say before you give a game away".
