Rybakina Dismantles Osaka, One Win From World No. 1

Clinical from the first game

Second seed Elena Rybakina needed just over an hour to end Naomi Osaka's 2026 US Open campaign, winning 6-1, 6-4 in a round-of-16 encounter that was rarely in doubt. The opening set took fewer than twenty minutes as Rybakina's flat, penetrating groundstrokes exploited an Osaka who was clearly restricted by a nagging Achilles tendon injury she had been managing throughout the tournament.

Osaka competed gamely — she generated 28 winners across the match — yet Rybakina conceded only 17 points in the opening set. The second set was closer in feel but no less decisive in outcome: a clean break at 4-3 put Rybakina in the driving seat, and she served out without facing a break point. In four matches at this US Open, the Kazakh has dropped a combined total of just 31 games.

One victory from world No. 1

The ranking arithmetic surrounding Rybakina's run gives Tuesday's result an extra dimension. Should she defeat qualifier Qinwen Zheng in the quarterfinals and advance to the last four, she will claim the world No. 1 ranking for the first time in her career.

"Of course I want it," Rybakina said courtside. "I don't know anyone who wouldn't wish for it. It's definitely one of my goals."

The obstacle between her and that milestone is formidable despite the qualifier tag. Zheng stunned Iga Swiatek 7-5, 6-3 to reach this stage — recovering from 0-5 down in the opening set in a performance that captured the attention of the entire tennis world. Rybakina leads their head-to-head 4-1, but Zheng arrives in the quarterfinals riding one of the great momentum waves of this US Open.

Osaka: philosophical in defeat

For a four-time Grand Slam champion whose last major title came at the 2021 Australian Open, Osaka found a composed way to frame her exit. The 13th seed had navigated to the round of 16 despite the Achilles problem, defeating Elise Mertens in three sets in the previous round while managing daily treatment for the injury.

"Honestly, I'm not disappointed now — it's a very strange feeling," Osaka said after leaving Arthur Ashe Stadium. "Maybe I'm just getting older, but I don't feel sad. My daughter's healthy, everyone in my family is great. I had the opportunity to play this Slam and I got as far as I could. It's only up from here, I guess."

The measured response reflects the shifted priorities of a player who returned from maternity leave and rebuilt her ranking to No. 13. The Achilles issue, which had been managed with daily treatment throughout the draw, ultimately cost her dearly against an opponent who punishes any hesitation in movement with a heavy serve and a flat, penetrating backhand.
