While Williams has been one of the main attractions at every tennis tournament she's played for the past 15 years, some of her fellow female players have felt the sting of not being superstars or, well... guys.
After her fourth-round loss, Wozniacki (who despite being a former world No. 1 has never won a grand slam title) noted "different" standards at Wimbledon when it came to which matches got scheduled on the show courts.
And Williams, though she's almost always on Centre Court at the All England Club, including for today's straight-set dispatching of Maria Sharapova in their semifinal, agrees with her bestie that there's a long way to go in the ongoing battle of the sexes in tennis.
"Every year there's two men's and one women's match on the main courts, Court No. 1 as well as on Centre Court," Williams said yesterday after her win over Victoria Azarenkain the quarterfinals. "We're still fighting on that. We've made some progress but hopefully we'll keep making more progress.
"We made sure that women have more featured matches. It's just a little bit at a time. Hopefully we'll get to the point where we'll even have more featured matches. I don't think it's limited to Wimbledon. We have this problem at a lot of different tournaments. Pretty much most of the tournaments that are both men and women.
"So I think it doesn't start here. It's a huge conversation that we have to have."
Williams and Wozniacki are longtime BFFs, both on the tour and off, and the athletes stepped out for dinner together last night in London. The stylish duo were joined by Drake, who's been a fixture in the fancy seats at Wimbledon this year.
When asked about Wozniacki and Williams' concerns, the All England Club said in a statement, per ESPN, that "scheduling of the program of matches to be played each day at The Championships is a complex operation."
"It may not be possible to satisfy the often conflicting requests, but in all cases fairness will be the objective," the club said.
