Serena Williams: Women are still fighting for equal rights
Serena Williams supports Caroline Wozniacki's accusation of sexist scheduling at Wimbledon and believes there is a "huge conversation" to be had about the issue at all grand slam tournaments.
Wozniacki hit out at Wimbledon organisers after she lost in the fourth round on Monday, insisting "different" standards mean women are given fewer opportunities than men to play on the All England Club's show courts.
Williams booked her place in the semi-finals on Tuesday after she came from a set down to beat Victoria Azarenka on Centre Court, and the American said afterwards there is work to be done on the scheduling of women's matches.
"We're still fighting on that," Williams said.
"We've made some progress but hopefully we'll keep making more progress.
"We made progress making 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."
During the first seven days at Wimbledon, only nine out of the 24 matches scheduled on Centre Court were from the women's draw.
