Marta Kostyuk vs Sloane Stephens preview
11th seed Marta Kostyuk will face off against wildcard Sloane Stephens in the second round of the 2026 US Open on Wednesday.
Kostyuk reached the second round with a 6-4, 6-1 win over qualifier Storm Hunter, continuing an excellent stretch through the majors this year that’s already included semifinal runs at both the French Open and Wimbledon. She’s chasing her first appearance past the round of 16 at Flushing Meadows.
Stephens, playing on a wild card, reached the second round with a 6-4, 6-1 win over Clara Tauson, backing up a career that’s included this exact title back in 2017. It’s a solid response after a two-match losing streak coming in, and she’ll draw on her experience as a former champion here against a red-hot Kostyuk.

Marta Kostyuk vs Sloane Stephens prediction
Kostyuk’s win in Cincinnati wasn’t especially close, two identical 7-5 sets that came down to a handful of key moments rather than one-sided dominance, but it does show she has a recent, tangible answer for whatever Stephens brings. That kind of psychological edge, especially this recently, tends to matter in a rematch.
Stephens, though, arrives with real belief of her own after a title-winning run in New York back in 2017 and a clean, efficient win over Tauson to reach this round. Her grinding, high-percentage baseline game has given plenty of higher-ranked players trouble over the years, and playing in New York in front of a supportive crowd could add an extra edge.
Given how recent and how tight their only meeting was, and Kostyuk’s superior season-long form overall, she looks like the narrow favorite to repeat that result, even accounting for Stephens’s experience and home-crowd advantage.
Pick: Kostyuk to win in straight sets.
