Naomi Osaka vs Elena Rybakina: US Open 2026 Round of 16 Preview

The US Open 2026 women's singles draw delivers another major showdown as Naomi Osaka faces Elena Rybakina in the fourth round. The match pits a four-time Grand Slam champion and two-time US Open winner against the No. 2 seed and 2026 Australian Open champion.

For Osaka, this is another opportunity to make a deep run in New York, while Rybakina arrives with one of the strongest records in the tournament so far. A place in the quarterfinals is on the line in what promises to be one of the most anticipated women's matches of the round.

Naomi Osaka's Road to the Round of 16

Osaka entered the second week of the tournament as the No. 13 seed and has already had to fight through several difficult moments in New York.

In the third round, Osaka defeated No. 23 seed Elise Mertens 6-3, 3-6, 7-5. The Japanese star had to deal with a lingering lower-leg issue during the match, but still managed to close out the deciding set and secure her place in the fourth round.

The victory also continued an impressive Grand Slam season for Osaka. For the first time in her career, she has reached the fourth round at three of the four Grand Slam events in the same calendar year.

Elena Rybakina's Dominant Start

Rybakina comes into the fourth round as the No. 2 seed and one of the tournament's most dangerous players.

The Kazakh player has been perfect in sets through her first three matches. Her latest victory came against Yuliia Starodubtseva, whom she defeated 7-6(6), 6-3 in the third round.

Rybakina's 2026 season has already included a major triumph at the Australian Open. She also reached the Toronto final before arriving in New York, making her one of the leading contenders for the US Open title.

Osaka vs Rybakina: Recent Meeting

This will be the second meeting between Osaka and Rybakina. Their previous encounter came less than a month ago in Toronto, where Rybakina recovered after losing the opening set to win 4-6, 7-6(5), 6-4.

That recent contest gives both players valuable information heading into New York. Osaka will know she has already pushed Rybakina to the limit, while Rybakina will look to use her powerful serve and aggressive baseline game to control the match earlier.

Why This Match Could Be Decided by the Serve

Rybakina's serve is one of the biggest weapons in the matchup. When she is landing her first serve consistently, she can shorten points and put immediate pressure on her opponent's return games.

Osaka possesses a similarly dangerous first strike. Her ability to attack with the serve and first forehand has made her particularly effective on hard courts, especially when she can dictate rallies rather than defend.

The battle between Rybakina's power and Osaka's returning and baseline aggression could therefore determine who controls the match.

What Is at Stake?

For Osaka, another victory would put her into the US Open quarterfinals and continue a remarkable return to the second week at her most successful Grand Slam.

For Rybakina, reaching the quarterfinals would keep her title challenge firmly on track. The No. 2 seed also entered the tournament with a major opportunity in the world rankings.

With both players possessing Grand Slam-winning experience, this Round of 16 contest has all the ingredients of a high-quality hard-court battle.

Naomi Osaka vs Elena Rybakina: Match Prediction

Rybakina enters with the stronger seed and a perfect 6-0 record in sets at the 2026 US Open, but Osaka has demonstrated considerable resilience to reach this stage.

The recent Toronto meeting suggests there may be very little between the two players. If Osaka can return Rybakina's serve effectively and avoid giving away cheap points, she has the ability to make this another extremely competitive encounter.

Rybakina's current form and consistency make her the slight favorite on paper, but Osaka's experience on the US Open stage means this is far from a straightforward matchup.
