The 2025 US Open has advanced to the round of 16, delivering a week of upsets, drama, and towering performances as players push toward the second week in New York. From American breakthroughs to early exits of top seeds, the path to the title is beginning to take shape.
Women’s highlights
– Madison Keys, the sixth seed, was upset by Renata Zarazua of Mexico, snapping Keys’ strong early-season form from the start of 2025.
– Coco Gauff continued to navigate service woes that have plagued her in recent rounds, showing frustration on the sidelines during her second-round win over Donna Vekic, before rebounding to handle Magdalena Frech in the third round to set up a mouthwatering fourth-round clash with Naomi Osaka.
– Unseeded Taylor Townsend produced another eye-catching result in New York, defeating No. 5 seed Mirra Andreeva in straight sets to reach the fourth round. Townsend, already one of the tournament’s feel-good stories, has credited her success in part to a remarkable doubles partnership with Katerina Siniakova and has added another chapter by advancing again in singles.
– Townsend’s latest moment came after a heated exchange with Jelena Ostapenko following a straight-set win, with Ostapenko reportedly telling Townsend she had “no class and no education” at the handshake.
Upcoming big matches in the women’s draw include Townsend vs Barbora Krejcikova, while other fourth-round ties feature top contenders such as Coco Gauff against Naomi Osaka and Iga Swiatek facing Ekaterina Alexandrova.
Men’s highlights

– The tournament’s top seeds have largely held serve, with Jannik Sinner and Carlos Alcaraz continuing to move through their rounds with minimal drama.
– American progress hit a snag as Ben Shelton, the No. 6 seed, retired with a shoulder injury while leading Adrian Mannarino. Two-time US Open semifinalist Frances Tiafoe also fell to veteran Jan-Lennard Struff.
