Naomi Osaka knocked Aryna Sabalenka out of Wimbledon on Sunday, winning in straight sets 6-2, 7-6(2).

What happened?

Osaka's serve was nearly untouchable, with her winning 33 of 38 points on her first serve.

She landed 70 percent of her first serves in the second set and won 22 of 23 of those points.

Why it matters for Naomi Osaka

This win is Osaka's biggest since she returned to the tour after pregnancy in 2024 and her first quarterfinals appearance at Wimbledon.

Osaka had never played a fourth-round match at the All England Club before, but she overpowered Sabalenka with a stunning display of controlled aggressiveness.

What comes next?

Osaka will move on to the quarterfinals of Wimbledon, marking a significant milestone in her career.

On Sunday, Osaka seemed to understand how to play with the surface, instead of against it, and unlocked the movement needed to thrive on grass.

She felt like the player she was before her hiatus to give birth to her daughter, Shai, at last year's D.C. Open in late summer.

The process took close to two years, but Osaka's transformation into a titan of grass-court tennis took its biggest leap forward on Sunday.

Osaka's serve numbers were borderline absurd, with nearly half of her first serves not coming back.

She weaponized her second serve, too, winning 61 percent of those points.

Sabalenka, on the other hand, had a difficult result, adding to her rocky performances on clay and grass surfaces.

She made the final of the Australian Open and completed a rare Sunshine Double with wins at the BNP Paribas Open at Indian Wells and the Miami Open.

But as the season moved to organic surfaces, her results grew unstable, including a quarterfinal meltdown at the French Open.

Sunday's match was more about Osaka's fire and savvy than Sabalenka's instability, with Osaka overpowering maybe the most overpowering player in the world.

Osaka and Sabalenka are both 28 years old, and Sabalenka is a three-time Wimbledon semifinalist, but Osaka's win was a significant upset.

The win was her first at Wimbledon in six previous appearances, which used to make sense but now makes none at all, especially with Osaka cranking her old-style booming serve that gave Sabalenka few openings.
