Kazakh tennis player Elena Rybakina defeated former U.S. Open champion Naomi Osaka 6-1, 6-4 on Monday, September 7, 2026, at Flushing Meadows in New York, reaching the U.S. Open quarter-finals and moving within one win of claiming the world number one ranking.
Elena Rybakina cleared another major hurdle in her pursuit of a third Grand Slam title by outclassing Naomi Osaka in a brisk 66-minute encounter at Louis Armstrong Stadium. The flawless victory booked a last-eight clash with Olympic champion Zheng Qinwen and left the second seed on the cusp of tennis history.
Match Domination and Osaka’s Injury Struggles
Rybakina raced through the opening set in just 22 minutes, converting two of her three break-point opportunities and sealing the frame with a booming serve. Osaka, the 13th-seeded player who arrived on court wearing a distinctive fur-collared overcoat featuring oversized signage and a mural-like city scene, offered stiffer resistance in the second set.
The match grew more complicated as Osaka battled physical setbacks. Osaka clutched her left leg at 2-2 in the second set, struggling with lingering effects from an Achilles niggle that had flared up during the third round. Despite the physical disadvantage, the 28-year-old managed to save a break point and stay competitive.
Rybakina maintained pressure with deep groundstrokes, capturing the decisive break in the seventh game when Osaka hit a forehand into the net. Reflecting on her performance, Rybakina noted how quickly momentum can shift on the court.
“I wasn’t expecting that. I played really well today and felt the ball was really good from my side. I am super happy with the performance.”

The Stakes: Chasing the World Number One Ranking
With this straight-sets triumph, Rybakina stands one match win away from dethroning Aryna Sabalenka and seizing the world number one spot in the WTA Rankings. Reaching the final four in New York would make her the 30th player to hold the top ranking since the WTA published its first list in 1975, while also making Kazakhstan the 16th different nation represented at the summit.
Statistically, Rybakina joins an elite historical tier. She is now the fourth active player to reach the quarter-finals at all four Grand Slams without conceding a set along the way, joining Venus Williams, Serena Williams, and Sabalenka. Furthermore, her career win rate against opponents who have held the world number one ranking trails only Serena Williams, Iga Swiatek, and Martina Navratilova among players with at least 25 such matches since 1975.
Next Steps Against Zheng Qinwen
Standing between Rybakina and the top ranking is Zheng Qinwen, who advanced following a comeback victory over Iga Swiatek. Rybakina remains focused on maintaining her strategy as she prepares for the quarter-final showdown.
