Since Saturday, the debate around the final has only gotten thornier. The US Open has fined Williams $17,000 (over £13,000) for her code violations, while the Women’s Tennis Association (WTA) supported Williams’ claims that she was subjected to sexist treatment by Ramos.

“The WTA believes that there should be no difference in the standards of tolerance provided to the emotions expressed by men vs women and is committed to working with the sport to ensure that all players are treated the same,” said WTA CEO Steve Simon in a statement.

“We do not believe this was done [on Saturday] night.”

The incident has also sparked debate about the widespread policing of black women’s emotions – particularly anger. A cartoon published in Australian newspaper the Herald Sun has been widely decried as racist for depicting Williams as a raging stereotype of a black woman, while Osaka is shown as a dainty figure with straight, blonde hair. (In reality, Osaka – who is of mixed Haitian and Japanese heritage – has curly hair.)

In the wake of the match and that cartoon, many black women have spoken out on social media to say that Williams’ treatment resonates with their own experiences.
