Day 5 of the US Open 2025 promises fireworks as the women’s draw heats up with some intriguing clashes. While the spotlight naturally falls on World No. 1 Iga Swiatek, who takes on the Netherlands’ Suzan Lamens, there are several other must-watch battles on the card. Here’s a breakdown of the action and predictions for who might come out on top.
Iga Swiatek vs Suzan Lamens
Swiatek has looked sharp in New York, sweeping through her early rounds with the authority expected of a world No. 1 and former US Open champion. Her aggressive baseline game, combined with her ability to switch gears defensively, makes her a nightmare opponent on hard courts. Lamens, ranked outside the top 50, deserves credit for her run so far—her crafty play and flat hitting have troubled opponents—but facing Swiatek on Arthur Ashe is an entirely different beast. Expect Lamens to put up a fight early, but Swiatek’s depth, variety, and mental toughness should see her cruise into the next round.
Prediction: Swiatek in straight sets.
Coco Gauff vs Marta Kostyuk
The defending US Open champion, Coco Gauff, has been feeding off the energy of the New York crowd. Her athleticism and improved serve give her an edge against Kostyuk, who brings firepower but sometimes struggles with consistency under pressure. Kostyuk will need to redline her game to stand a chance, but Gauff’s confidence and defense make her the heavy favorite.
Prediction: Gauff in two tight sets.
Aryna Sabalenka vs Emma Navarro
Sabalenka’s all-out aggression meets Navarro’s rising confidence and composure. The American will have the crowd behind her, and her counterpunching game could extend rallies, but Sabalenka’s sheer firepower usually overwhelms opponents outside the top 10. Navarro might steal a set if Sabalenka has an off-patch, but the Belarusian’s big-match experience should see her through.
Prediction: Sabalenka in three sets.
