Coco Gauff and Osaka Shine on Blockbuster US Open Day
The second week at the US Open starts with a jolt.
Coco Gauff, the defending champion and No. 4 seed, returns to Arthur Ashe Stadium on Monday night chasing a second title in New York. She has barely broken a sweat so far, rolling through her first three rounds in straight sets. The tennis has looked clean, controlled, almost ruthless.
Now comes the first real examination.
Across the net will be No. 14 seed Iva Jovic, who has already shown she can dig in and suffer. On Friday she had to go the distance to knock out No. 17 Alexandra Eala, surviving a three-set scrap to book her place in the fourth round. Gauff has not yet been dragged into that kind of trench warfare at this tournament. Jovic will try to change that when they walk out at 7 p.m. ET.
The night session belongs to Gauff. The day, though, may be remembered for Naomi Osaka.
Osaka returns to the big stage against Rybakina
On paper, No. 2 seed Elena Rybakina against No. 13 seed Naomi Osaka is just a fourth-round match. In reality, it feels like a main-event final dropped into the middle of the schedule.
Osaka, a two-time US Open champion, knows this court better than most. She has lifted the trophy here, twice handled the pressure, twice owned the New York noise. Rybakina arrives as one of the most complete hard-court players in the game, with a serve that can blow open any rally and a baseline game built for this surface.
They are set for 2:30 p.m. ET, a slot that will pull eyes from every corner of the grounds. Rybakina carries the higher seeding and the recent results. Osaka carries the history of this place. It is the kind of matchup that can tilt the balance of a draw in a single afternoon.
Swiatek, Andreeva, and a packed women’s slate
The women’s fourth round starts early and starts strong.
At 11 a.m. ET, No. 5 seed Maria Andreeva faces No. 24 Anastasia Potapova in a clash of contrasting styles and temperaments. It’s the sort of match that can quietly shape the quarterfinal picture before the marquee names even hit the court.
Half an hour later, at 11:30 a.m., No. 8 seed Iga Swiatek meets Qinwen Zheng. Swiatek, a multiple major champion, brings her familiar mix of precision and intensity, while Zheng has the power to knock anyone off their rhythm if she finds her range. If Swiatek blinks, Zheng has the tools to punish her.
By the time Rybakina and Osaka take the stage in mid-afternoon, the women’s draw could already look very different.
Gauff’s prime-time showdown with Jovic closes the women’s action on Monday. Straightforward so far, yes. But the second week rarely lets anyone stroll.
Zverev leads the men’s charge
On the men’s side, the top seed steps into the spotlight.
Alexander Zverev, the No. 1 seed, anchors the evening session at 8:30 p.m. ET against No. 21 Luciano Darderi. Zverev carries the weight of expectation and the target on his back; Darderi arrives with nothing to lose and a chance to detonate the draw under the lights.
Before the headliner, the day builds in layers.
At 1 p.m., No. 24 Francisco Cerundolo faces No. 28 Alexander Blockx in a battle that promises long rallies and little margin for error. At 4 p.m., No. 14 Learner Tien takes on Karen Khachanov, a test of whether Tien’s rise can withstand the muscle and experience of a proven big-stage performer.
At 4:30 p.m., Arthur Gea meets Botic van de Zandschulp, a match that may not command the biggest court but could easily deliver the kind of five-set chaos that defines the first half of week two.
Then comes Zverev. Then comes the noise.
Quarterfinals already looming on Tuesday
While Monday decides who survives, Tuesday starts to decide who truly contends.
On the women’s side, the quarterfinals will feature No. 1 Aryna Sabalenka against No. 6 Linda Noskova, and No. 3 Jessica Pegula against No. 26 Emma Navarro. Sabalenka’s power, Noskova’s fearlessness, Pegula’s consistency, Navarro’s surge into the top tier — all of it will crash together with a semifinal spot on the line.
The men’s quarterfinals are no quieter.
No. 2 Carlos Alcaraz faces No. 8 Ben Shelton in a showdown built for the New York stage: explosive shot-making, raw speed, and no interest in playing it safe. No. 11 Frances Tiafoe meets Alex Michelsen in an all-American clash that will carry the crowd with it point by point.
Monday’s winners will step into that world. Monday’s losers will walk out into the New York night, their US Open over.
The schedule is set. The second week is here. Now it’s up to the players to decide who belongs in the closing acts of this tournament.
