The three-time defending champion up against a red-hot Osaka in Madrid!

Aryna Sabalenka reaches the round of 16 with the calm of a player who has never lost the thread in this tournament. Stearns 7-5 6-3, Cristian 6-1 6-4, 25–1 in 2026, 14 wins in a row, three Madrid titles to her name. The match against Cristian was a showcase of pure serving, 100% of service games held, no breaks conceded, a devastating return with 52% won on the opponent’s second serve. Against Stearns she managed things more, five double faults, six break points saved out of eight, but she held firm in the moments that mattered. That’s been the constant of her season: even when imperfect, she wins the big points.

On the other side, Naomi Osaka shows up with a face Madrid hadn’t seen since 2019. Osorio dispatched 6-2 7-5, Kalinina dominated 6-1 6-3 in 1h16 with 75% of the total games. What stands out when you watch her two matches is the movement: she covers the court with a rediscovered physical ease, she anticipates, she hits early and hard. The 33 winners against Kalinina tell the story of an offensive, uninhibited player on clay. The H2H is 1-1, never played on clay, and Sabalenka herself admitted that this post-maternity Osaka is a different player from the one she used to know.
