Ranked No 85 in the world before the tournament, Mboko will leap 60 places into the top 25. She needed just over two hours to overcome Osaka, who is currently ranked No 49. Osaka will also leave Canada inside the top 25 – her best position since 2022. The Japanese star, whose last title came at the 2021 Australian Open, was playing her second final of the year after Auckland.
How much prize money did Mboko win in Montreal?
“I want to thank Naomi for an amazing match. I’ve always admired you since I was a little girl, so it’s such an honor to play against such an incredible player as you,” the homegrown champion said with grace.
Along with the 1,000 ranking points that catapult her into the WTA elite, Mboko pockets $752,275 in prize money for her triumph in Canada.
