Pliskova and Osaka can both take the place of N.1 world after the defeat of the winner of the last Roland-Garros, the Australian Ashleigh Barty, Tuesday in the second round.

For a place in the quarter-finals, Pliskova, 27, will face Estonian Anett Kontaveit (19th) who took advantage of the loss of Spain's Carla Suarez (26th) while leading 7-5, 3 -1.

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.
