SERENA WILLIAMS said Sunday that she will not go to the Tokyo Olympics, but did not want to say why during her pre-Wimbledon video conference with reporters.

“I’m actually not on the Olympic list. ... Not that I’m aware of. If so, then I shouldn’t be on it,” Williams said.

The 39-year-old Williams has won four gold medals at past Summer Games for the United States: in both singles and doubles at the 2012 London Olympics — which held the tennis competition at the All England Club — and in doubles at the 2000 Sydney Olympics and 2008 Beijing Olympics.

All of her doubles golds were won with her older sister, Venus, as her partner.

At the 2016 Rio de Janeiro Games, Serena Williams lost in the third round of singles to Elina Svitolina of Ukraine and the siblings were beaten in the first round of doubles. Before that, they had been 15-0 as an Olympic doubles team.

“There’s a lot of reasons that I made my Olympic decision,” Williams said the day before the start of main-draw action at Wimbledon, where she will try to collect her 24th Grand Slam singles title. “I don’t really want to — I don’t feel like going into them today. Maybe another day. Sorry.”

Williams joins a growing list of top ranked tennis players opting not to travel to Tokyo in July.

Reigning U.S. Open champion Dominic Thiem announced June 17 he would not compete in Tokyo. Thiem at the time said on Twitter he did not “feel ready to play his best.” Thiem was later forced to withdraw from Wimbledon because of a wrist injury.

Rafael Nadal announced that same day he would not compete in Wimbledon or Tokyo. “After listening to my body and discuss it with my team I understand that it is the right decision,” Nadal then wrote on Twitter.

Roger Federer said Saturday he would not make his decision to participate in this year’s Games until after Wimbledon.(SD-Agencies)
