Naomi Osaka of Japan, N.2 World, qualified for the round of 16 of the WTA tournament in Toronto, resulting in the fall of the Australian Ashleigh Barty of her N.1 world.

By beating Germany's Tatjana Maria (74th overall) 6-2 and retire, Osaka, victorious in the 2018 US Open and the 2019 Australian Open, is not yet sure of going back to the top of world tennis. .

Karolina Pliskova of the Czech Republic, third world player and also qualified for the round of 16 also has the opportunity to become "queen" of women's tennis again.

If Pliskova won in the final, even against Osaka, she would become N.1 world, while the Japanese must reach at least the quarterfinals to find the head of the WTA ranking in case the Czech would reach the final four.
