The stage is set for an exciting rematch between Coco Gauff and Naomi Osaka at the 2025 US Open. Gauff powered through a resounding 6-3, 6-1 victory over Magdalena Frech, showing signs of an improved serve this time. Osaka, on the other hand, overcame Daria Kasatkina in a gritty three-set battle (6-0, 4-6, 6-3) to reach her first Slam fourth round since 2021.
Osaka’s return to form has been equally compelling as Gauff’s. After becoming a mother and taking a hiatus, the Japanese won a WTA 125 title on clay (L’Open 35 de Saint-Malo) and made a deep run to a WTA 1000 final in Montréal. Her improvements under new coach Tomasz Wiktorowski are evident as she regains confidence in big moments.

Gauff vs. Osaka Head-to-Head
Gauff and Osaka have played each other five times on the professional circuit, with the American leading the rivalry 3–2. Their most recent meeting came at the China Open in October 2024, when Osaka was forced to retire due to a back injury while trailing Gauff by one set apiece.
Their first encounter was in the third round of the 2019 US Open at Arthur Ashe Stadium, where Osaka defeated a 15-year-old Gauff 6-3, 6-0 in just over an hour.
Gauff vs. Osaka Prediction
Gauff has established herself as a dominant force: she’s undefeated across all 8 of her WTA Tour final appearances on the surface. This contrasts with Osaka, who has secured 7 hard-court titles but suffered 6 final losses. Gauff’s perfect finals record (8–0) on hard highlights not only her consistency but also her ability to close high-stakes matches. In comparison, Osaka’s 7–6 final record suggests some volatility, though she remains very capable under pressure.

The available China Open match data shows that Gauff executed 6 aces in one of their recent clashes, converting a high 83.3% of her break points, and winning 65.6% of points on her first serve. Osaka’s serve in that match, by contrast, produced only 1 ace, and she won just 53.8% of first-serve points, plus converted only 37.5% of break points.
Gauff is riding a wave of success on hard surfaces: she’s won every hard-court final she’s reached, including major tournaments like Cincinnati and the US Open. Osaka, despite her Grand Slam pedigree, has had mixed results. Her most recent hard-court final at the Canadian Open ended in a loss to Victoria Mboko, extending her title drought since the 2021 Australian Open.
Gauff’s comprehensive hard-court strength, undefeated record in finals, superior serve metrics in their head-to-head, and recent consistency make her the logical pick heading into this showdown.
Prediction: Gauff to win in three sets
