Responding to a challenge from a fan, Andy Murray writes in his BBC column that he's up for facing Serena Williams in a battle of the sexes showdown in Las Vegas.

“I have been challenged by someone on Twitter to taking on Serena Williams,” Murray wrote. “I'd be up for it, why not? I've never hit with her but she's obviously an incredible player and I think people would be interested to see the men play against the women to see how the styles match up. It's happened in the past with Jimmy Connors and Martina Navratilova. How about Las Vegas as a venue?”

Williams seemed surprised by Murray's challenge; she said it would be fun to face him, but doubts "I'd win a point."

“He wants to play me? Is he sure?” Serena said with a laugh. “That would be fun. I doubt I'd win a point, but that would be fun. I get alleys. He gets no serves. I get alleys on my serves, too. He gets no legs.

Two-time Roland Garros champion Serena, who has won Grand Slam titles on every surface,  says she'd pick clay for the match.

“Indoor, grass, I'm going to have to choose grass indoor. Actually, I might go clay," Serena said. "I think I might go clay with him. He loves grass. I do, too. But I'm going to definitely go clay.”
