Respect me and my privacy as I’m trying to have a baby. Good day sir- Serena Williams (@serenawilliams) June 26, 2017McEnroe, a former player and now TV commentator, said Williams is the best women’s tennis player in history – “no question.” But when asked whether she was the sport’s best ever, regardless of gender, he made clear he didn’t think so.He said he thought Williams could beat some men, “but if she had to just play the circuit – the men’s circuit – that would be an entirely different story.” He said if she tried to be part of the men’s tour, “she’d be like 700 in the world.”In one of her tweets, Williams wrote : “I’ve never played anyone ranked ‘there’ nor do I have time.”She added: “Respect me and my privacy as I’m trying to have a baby. Good day sir.”Williams is taking a break from the tennis tour because she is pregnant. She plans to return to competition in 2018.advertisementThe American has won 23 Grand Slam singles titles, a record in the Open era, which began in 1968.McEnroe won seven major titles.
