Naomi Osaka will not be taking home a medal in Tokyo after losing to Marketa Vondrousova of the Czech Republic on Monday night.
Vondrousova advanced to the Olympic quarterfinals with a 6–1, 6–4 victory.
Osaka won her first two matches in Tokyo as she returned to the court after taking a break for her mental health. Osaka withdrew from the French Open in May after refusing to participate in media availabilities. Osaka noted she suffers from anxiety, which is exacerbated when she has to speak with the press.
"I think the best thing for the tournament, the other players and my well-being is that I withdraw so that everyone can get back to focusing on the tennis going on in Paris," Osaka wrote in a social media post.
