Naomi Osaka back as World No.1

Naomi Osaka (JPN) regained the top spot in the WTA rankings after her quarterfinal appearance at the Rogers Cup in Toronto. 

Osaka first captured the World No. 1 ranking after winning her second consecutive Grand Slam at the Australian Open in January this year. At that time, she became the first Japanese player - male or female - to sit atop the rankings. 

To celebrate Osaka’s historic rise to the top of the WTA rankings earlier this year, Yonex released the EZONE Limited Edition racquet, a gold racquet designed in collaboration with Osaka. Osaka debuted this commemorative racquet in Toronto last week, where only 10,000 racquets were produced globally.
