McEnroe's views anger Serena
Serena Williams has asked John McEnroe for "respect" after the seven-time Grand Slam champion said his fellow American would be ranked "like 700 in the world" if she had to play on the men's circuit.
Former world No. 1 Williams, who has taken time off to have a baby, responded testily on Twitter.
"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." - REUTERS
