Tokyo Olympics: Serena Williams confirms she won't be at Games

Serena Williams has confirmed that she will not participate in the tennis tournament at this summer's rescheduled Tokyo Olympics.

Nadal, Thiem have also chosen to sit out Olympics

Rafael Nadal and Dominic Thiem have already opted out of featuring at the Games next month, with Roger Federer and Novak Djokovic yet to commit.

Williams, who made her Olympics debut in 2000 and has four gold medals, is now atop the list of big-name absentees, having previously expressed reservations because she would not be able to take her three-year-old daughter Olympia along with her.

Williams not drawn on reasons for Tokyo snub

"I'm actually not on the Olympic list – not that I'm aware of. If so, then I shouldn’t be on it," she said at a pre-Wimbledon news conference.

"There's a lot of reasons that I made my Olympic decision. I don’t feel like going into them today. Maybe another day. Sorry."

Williams will begin her pursuit of an eighth Wimbledon and 24th grand slam singles title against Aliaksandra Sasnovich on Tuesday.
