Naomi Osaka has moved up to WTA World No.7 after sealing her first major title at the US Open on Saturday, where she defeated Serena Williams in straight sets.
She has moved 12 spots up the ladder, overhauling last year’s champion in New York, Sloane Stephens, who has dropped six places to WTA World No.9.
Japan’s first Grand Slam champion has also become the youngest player in the Top 10 at the age of 20, overtaking Latvia’s Jelena Ostapenko in this regard.
Elsewhere among this elite club of players, Angelique Kerber moved up one spot to WTA World No.3, while Caroline Garcia jumped two positions to move directly behind the German, as Romania’s Simona Halep and Denmark’s Caroline Wozniacki retain the top positions. Elina Svitolina also jumped up one place, moving to WTA World No.6.
