Karolina Muchova [11] vs. Marta Kostyuk [27] (TBD)

When Are Aryna Sabalenka and Iga Swiatek Going to Play?

The two best players in the world will compete in their respective pre-quarterfinals on different days. World No. 1 and defending champion Aryna Sabalenka is set to take on unseeded Spaniard Cristina Bucsa on Sunday evening. Provided the Belarusian powerhouse can come through the contest, there could be a mouth-watering quarterfinal against Elena Rybakina lined up on Tuesday.

The other end of the draw will feature Iga Swiatek battling 13th seed Ekaterina Alexandrova of Russia. The Polish sensation, arguably the most in-form WTA starlet at the moment, has won four out of her six matches against Alexandrova. The match will take place on Monday at TBD. A victory for the 24-year-old could confirm a rematch of the Wimbledon 2025 final against Amanda Anisimova – the American will face Beatriz Haddad Maia of Brazil in her Round of 16.

In perhaps the match of the tournament thus far, two former champions are set to collide. No. 3 seed Coco Gauff will meet four-time Grand Slam champion Naomi Osaka in the US Open 2025 Round of 16 on Monday. It will be their first clash in 2025, and second at this event. Gauff leads the head-to-head against Osaka by 3-2, including victories in their last two encounters.

The winner of Coco Gauff vs Naomi Osaka will take on either Karolina Muchova or Marta Kostyuk in the quarterfinal stage.
