Williams called Ramos a "thief' and a "liar" for charging her with a point penalty, and also slammed her racket to the court, breaking it during the match". Will rules change in Serena's matches? Osaka, who became the first-ever Japanese-born Grand Slam victor, said she was crying when she heard the boos, because she thought they were aimed at her.
Writing in The New York Times, Navratilova - the American 18-time grand slam victor - felt that Williams had some point in her argument with the officials, but that her behaviour was inexcusable, and something which was a bad look for those watching on.
But her claims were soon undermined by statistics showing that there were 86 code violations handed out to male players at the US Open, and only 22 to women. "I think the umpire, he did what was within his rights".
Tennis legend Martina Navratilova also criticized Williams this week, writing in The New York Times, "We can not measure ourselves by what we think we should also be able to get away with". That enraged Williams, and her reactions started the process by which Williams ended up losing a point and a game for racket abuse and verbal abuse, respectively.
"This week has been a dream come to life, and I'm so honored to represent Japan and Nissan on the world stage", Osaka said. "But in my mind, I really wanted to know what was going on".
Deadly Florence trudges inland in Carolinas with 'epic' rain, flooding
The storm is likely to bring significant rain to the Carolinas, where some places could see upwards of 20 inches, the update said. The rising sea crept towards the two-storey home of Tom Copeland, who lives on a spit of land surrounded by water in Swansboro.
The 20-year-old powered her way through the fortnight with the loss of just one set, culminating with a victory over her idol and 23-time major champion Serena Williams in the final.
She also called Ramos a "thief" for taking a point from her.
Williams' antics during her heated exchange with Ramos have since become the biggest controversy in the sporting world for the past week, with tennis greats speaking out both to condemn and support Williams' explanations for her behavior.
Ramos belatedly received public backing from the International Tennis Federation (ITF) and took his place in the chair for Cilic's routine 6-1 6-3 7-6 (7-5) win over Tiafoe.
It remains to be seen whether Serena will face any further ramifications for her behaviour, after being fined $17,000 in the wake of the incident. A pleaser. I keep thinking about what Claudia Rankine wrote about Ms. Williams in a 2015 article for The New York Times: "Once recognized, black excellence is then supposed to perform with good manners and forgiveness in the face of any racist slights or attacks". Most of those criticisms - largely made by men - were valid, but they chose to ignore Williams' experience as a black woman.
