Tennis: Superstars Naomi Osaka, Rafa Nadal withdraw from Wimbledon

Naomi Osaka has withdrawn from this month's Wimbledon championships for personal reasons, but her agent says the world No.2 will be ready for the Tokyo Olympics.

Japan's Osaka quit the French Open last month, after organisers fined her US$15,000 and threatened her with expulsion from the tournament for refusing to attend mandatory post-match press conferences.

The 23-year-old, who said she has "social anxiety", explained that the media's line of questioning after matches impacted her mental well-being.

"Naomi won't be playing Wimbledon this year," says her agent. "She is taking some personal time with friends and family.

"She will be ready for the Olympics and is excited to play in front of her home fans." 

Wimbledon organisers - the All England Lawn Tennis Club (AELTC) - say Osaka will be "greatly missed" at the Grand Slam this year.

"We completely understand her decision," the AELTC says. "We wish her a happy time with her friends and family, and look forward to welcoming her back to Wimbledon next year."

Osaka's participation at Wimbledon was in doubt this month, when she pulled out of a WTA 500 grasscourt tournament in Berlin, which was meant to serve as a tune-up for the Grand Slam.

Osaka, a four-time Grand Slam winner, had announced before the French Open that she would not face the media and stuck to her stance.

A strongly-worded letter from the board of the four Grand Slam tournaments followed, warning her of possible expulsion from Roland Garros and future majors, after which she announced her withdrawal on social media.

Osaka's sudden withdrawal led to an outpouring of support from fellow tennis professionals and other athletes, including Venus and Serena Williams, Formula One champion Lewis Hamilton and former Olympic sprint champion Usain Bolt.

Judy Murray, mother of three-times Grand Slam winner Andy Murray, also supported Osaka, saying tennis players faced extremely high demands from the media.

The reaction to Osaka's withdrawal put French Open organisers on the back foot. Although they defended their handling of the situation, they accepted that the governing bodies need to do better on mental health issues.

Osaka's withdrawal is a second major blow to Wimbledon, after 20-time Grand Slam winner Rafa Nadal announced he was skipping the grasscourt major following a gruelling claycourt season.

Spaniard Nadal also says he will skip the Olympics, which begin on July 23.

"I have decided not to participate at this year's championships at Wimbledon and the Olympic Games in Tokyo," he tweets. "It's never an easy decision to take, but after listening to my body and discussing it with my team, I understand that it is the right decision."

Born to a Japanese mother and a Haitian father, Osaka grew up idolising 23-time Grand Slam champion Serena Williams and turned professional in 2013, aged 15.
