Our Marta Kostyuk vs Sloane Stephens Prediction
The Difference Maker: Kostyuk is 5-2 in third-round matches in 2026. Moreover, she has never lost to a player outside the top-100 this year.
As for Stephens, she has never won a match against a top-20 player in the last two years.
What to Expect: Stephens deserves credit for her two morale-boosting wins over Kraus and Potapova. Unfortunately, her run is about to end at the hands of Kostyuk, who has been the most consistent performer on the tour since Spring.
Kostyuk should easily overpower Stephens, who still looks a shell of her former self.
