Serena Williams is holding her ground on claims of sexism against chair umpire Carlos Ramos, following her explosive outburst at last week's US Open final defeat.
Williams, 36, a 23-time single grand slam champion, was given three separate code violations in her loss in the US Open final, resulting in Naomi Osaka being awarded a crucial point penalty which gifted her game seven of the second set, then an even more crucial game penalty to gift her the next game, and a 5-3 second set lead.
She would later add that the incident was sexist, and that male players are able to get away with worse on-court infringements.
Appearing on Australia's The Project, Williams spoke publicly for the first time about the ordeal.
"I just don't understand … if you're a female you should be able to do even half of what a guy can do," Williams said.
Williams also hit back at Ramos' claims that she'd received coaching from trainer Patrick Mouratoglou - which he'd admitted to - denying her own involvement.
"He said he made a motion."
"I don't understand what he was talking about. We've never had signals."
