Two former top-10 players are set to collide at Flushing Meadows, where Naomi Osaka and Daria Kasatkina will battle for a spot in the US Open Round of 16. This third-round showdown represents more than just another match–for Osaka, it’s a chance to build on her remarkable comeback story, while Kasatkina looks to prove her hard-court game can shine on tennis’s biggest stage.
Osaka strode confidently into this encounter after dismantling Hailey Baptiste 6-3, 6-1, reaching her first US Open third round since 2021. The Japanese star’s dominance was complete, showcasing the power and precision that once made her the world’s top player. Meanwhile, Kasatkina earned her place through sheer grit, mounting a thrilling comeback against Kamilla Rakhimova. Trailing 4-1 in the decisive set, the Russian clawed back to secure a 6-2, 4-6, 7-5 victory that set up this compelling clash.
Osaka’s 2025 campaign has been nothing short of inspiring. She reached the final in Toronto, marking her first WTA 1000 final since returning from maternity leave. That breakthrough moment catalyzed an impressive run of form–she’s won eight of her last nine matches under coach Tomasz Wiktorowski, rediscovering the consistency that once carried her to four Grand Slam titles.
The transformation has been remarkable to witness. While Kasatkina dispatched Elena-Gabriela Ruse in straight sets before her hard-fought win over Rakhimova, her season lacks the same momentum. The Russian’s year has been relatively modest, highlighted by a quarterfinal in Adelaide and a fourth-round appearance at the Australian Open, but without the standout runs that have defined Osaka’s resurgence.

Osaka vs Kasatkina Head-to-Head
Osaka holds a perfect 2-0 record against Kasatkina, though their limited history intrigues this matchup. Their most recent clash came at the Internazionali BNL d’Italia, where Osaka controlled proceedings with a straight-sets 6-3, 6-3 victory. That encounter lasted approximately 1 hour and 15 minutes, showcasing Osaka’s ability to dictate play against the crafty Russian.
However, head-to-head records only tell part of the story. Both players have evolved since their last meeting, and Kasatkina’s never-say-die attitude was on full display during her comeback against Rakhimova. That mental toughness could prove crucial against an opponent historically dominating their rivalry.
Osaka vs Kasatkina Prediction
Naomi Osaka brings impressive hard-court credentials into this US Open showdown. Her 27-12 win-loss record in 2025 tells the story of a player finding her rhythm again. Most notably, she’s reeled off five consecutive tour-level wins, which she hasn’t achieved since her 2022 Miami Open run.
Osaka’s game has evolved dramatically. While her style remains rooted in powerful baseline aggression, this US Open has showcased a refined tactical approach. Her dismantling of Baptiste demonstrated this perfectly controlled power, combined with clever court positioning.

Kasatkina enters 2025 with a 17-19 win-loss record, numbers that don’t fully capture her dangerous game. While her baseline style is typically built for clay–her favorite surface, according to her official bio–she’s proven capable of making a significant impact on hard courts when her timing clicks.
Osaka’s 2025 numbers across all surfaces show 39 matches played, 226 aces logged, 77.9% of her service games won, and 73.5% first-serve points won, with a 32.3% return games won rate. She’s maintaining a 70.0% win rate, averaging 7.1 aces per match, with a double fault rate of 3.79 per match, and converting 44.7% of her break points in 2025, showing areas for improvement.

Kasatkina’s numbers tell a different story entirely. Across 38 matches in 2025, she’s hit just 59 aces but won 61.2% of her service games while achieving an impressive 44.4% return games won rate. On hard courts specifically, she maintains a 59.5% win rate, averaging 1.67 aces per match, with a first-serve percentage of 67.8%, and converting 46.6% of break points.
These statistics highlight the contrast in styles. Osaka relies on power and aggressive serving, while Kasatkina excels at neutralizing opponents’ weapons and creating opportunities through superior return games. The question becomes whether Osaka’s improved consistency can overwhelm Kasatkina’s counter-punching skills.
Prediction: Daria Kasatkina to win in three sets
