Kostyuk vs Stephens WTA Tennis Preview
Marta Kostyuk enters her US Open second-round clash with Sloane Stephens as the stronger betting side after beating her 7-5, 7-5 in Cincinnati. The No. 11 seed is 33-8 this season and arrives with elite confidence after winning Madrid and reaching Grand Slam semifinals at Roland Garros and Wimbledon.
Stephens remains dangerous despite her No. 209 ranking, especially after dismissing Clara Tauson in straight sets. Her counter-punching style could benefit from New York’s slower courts, but Kostyuk’s superior recent form, serve and movement give her the cleaner betting profile in this quick hard-court rematch.
