Naomi Osaka became the latest casualty in an upset-ridden few days at the Tokyo Olympics, falling to Marketa Vondrousova in a third-round stunner on Tuesday, 6-1, 6-4.

The Top 3 players on the WTA rankings were all in the singles draw in Tokyo and they’ve now been taken out one day after another: No. 1 Ashleigh Barty fell to Sara Sorribes Tormo in the first round on Sunday; No. 3 Aryna Sabalenka fell to Donna Vekic in a second-round match on Monday; and now No. 2 Osaka is out in the third round to Vondrousova.

With No. 4 Sofia Kenin and No. 5 Bianca Andreescu not playing, No. 6-ranked Elina Svitolina is now the highest-ranked player left in the draw in the Japanese capital. The Ukrainian outlasted Greece's Maria Sakkari in her third-round match, 5-7, 6-3, 6-4.

After Vondrousova raced out to a 4-0, double-break lead and eventually pocketed the first set in 24 minutes, the No. 2-ranked Osaka looked like she was starting to build a comeback, breaking in the first game of the second set and then holding for 2-0. But Vondrousova got the break back for 2-all and eventually broke one last time in the last game of the match—Osaka clawed her way out of double match point serving at 4-5, 15-40 and had two chances to hold for 5-all, but Vondrousova closed it out.

The Czech finished the day with just 10 unforced errors, Osaka 32.


Vondrousova's win over No. 2 Osaka is her fourth career Top 10 win, and third over a No. 2.

Vondrousova's win over No. 2 Osaka is her fourth career Top 10 win, and third over a No. 2.

Before today, Vondrousova was best known for having reached her first Grand Slam final on the clay of Roland Garros in 2019, where she finished runner-up to Barty.

The Czech’s win over Osaka is tied for the best win of her career—she defeated Simona Halep twice when she was ranked No. 2 in 2019, at Indian Wells and Rome.

“I think this is one of the biggest [wins of my career], for sure,” Vondrousova told after the match. “I beat Simona twice, but I think Naomi, she is the greatest now, the greatest in the game, and she’s also the face of the Olympics.

“It was tough for her, I think, to play like this. But I’m too happy now.”

Osaka spoke to the press about the pressure of playing her first Olympics at home.

“For me, I feel l should be used to it by now, but at the same time, I think the scale of everything is a bit higher because of the break that I took. I’m glad I didn’t lose in the first round, at least,” the four-time Grand Slam champion said. “I’m really glad to be here. I’m sad that I lost, of course, but all in all really happy with my first Olympic experience.”

“It’s so much pressure, I cannot imagine,” Vondrousova said of Osaka's situation. “I know how it is to be under pressure. It’s tough. But I think she didn’t play a bad match—she was fighting all match, staying calm, and she was fighting until the very end.”
