Billie Jean King says the future for women's tennis is "dynamite" on and off the court thanks to young stars like Coco Gauff and Naomi Osaka.
American King, 76, was a trailblazer for gender equality in tennis in the 1970s, also using her platform to fight for other equal rights in society.
Gauff, 16, and Osaka, 22, have both protested and spoken out about racism following the death of George Floyd.
"I know them a little bit and they are amazing people," said King.
At a peaceful protest in Florida last month, Gauff urged people to vote and act against racism.
