Williams takes issue with Djokovic comment
Disgraced BNP Paribas Open Tournament Director Raymond Moore may have resigned, but the debate raged on over equal pay for male and female tennis players Tuesday.
A day after Moore resigned for commenting to the media that female players should be grateful to their male counterparts "because they ride on the coattails of the men", No. 1-ranked Serena Williams took issue with a comment made by men's No. 1 Novak Djokovic that "I think that our men's tennis world, ATP world, should fight for more, because the stats are showing that we have much more spectators on the men's tennis matches."
Williams responded by saying "If I have a daughter and she plays tennis, and I have a son who plays tennis, I wouldn't say that my son deserves more money because he's a man. I would say they deserve the same amount of money.
"I think (Djokovic) is entitled to his opinion. But if he has a daughter — I think he has a son right now — I think he should talk to his daughter and tell her his son deserves more money than you because he's a boy."
