Serena Williams fired back Monday at John McEnroe's remark that she would only rank about 700th on the men's tennis circuit.


On Monday, Williams responded in two Twitter posts.

'Dear John, I adore and respect you but please please keep me out of your statements that are not factually based,' she wrote.

'I've never played anyone ranked 'there' nor do I have time. Respect me and my privacy as I'm trying to have a baby. Good day sir.'
