2026 US Open: Gauff, Osaka, Zverev Shine in Key Matches
Coco Gauff under the lights. Naomi Osaka back in a marquee slot. Carlos Alcaraz and Ben Shelton waiting in the wings on Tuesday. The 2026 US Open is moving into the teeth of the tournament, and the schedule is starting to look like a second-week classic.
Gauff steps into prime time
Coco Gauff’s title defense takes its most serious turn yet on Monday night. The No. 4 seed, cruising so far with three straight‑sets wins, gets the evening showcase at 7 p.m. ET against No. 14 seed Iva Jovic in the women’s fourth round.
Gauff has handled everything in front of her with authority this week. No drama, no fifth gear required. Jovic has already had to dig deeper. She needed a deciding set on Friday to edge No. 17 seed Alexandra Eala, a reminder that she’s battle-tested and not likely to be intimidated by the New York stage.
Gauff, though, owns that stage now. A second US Open crown is the mission. Monday night is where that campaign can either sharpen or suddenly look vulnerable.
Rybakina–Osaka: heavyweight clash in the afternoon
If Gauff is the headliner after dark, the afternoon belongs to one of the most intriguing matchups of the tournament: No. 2 seed Elena Rybakina against No. 13 seed Naomi Osaka at 2:30 p.m.
Rybakina brings the full modern power package, a top seed playing like one. Osaka brings history and aura. A two-time US Open champion, she knows exactly what it takes to own this court and this crowd, even if she enters as the lower seed.
It’s a collision of eras as much as styles: a current force against a champion intent on proving she still belongs at the very top.
Swiatek, Andreeva and the early wave
The day session on the women’s side starts with serious quality.
At 11 a.m., No. 5 Maria Andreeva faces No. 24 Anastasia Potapova, a matchup loaded with shot-making and nerve. At 11:30 a.m., former world No. 1 and four-time major winner Iga Swiatek, seeded No. 8, takes on Qinwen Zheng, one of the most dangerous floaters in any draw.
By the time Rybakina and Osaka walk on court, the women’s fourth round could already have delivered a few jolts.
Zverev anchors the men’s night card
On the men’s side, the top seed steps into the spotlight. No. 1 Alexander Zverev closes the Monday schedule against No. 21 Luciano Darderi at 8:30 p.m.
Zverev has carried the weight of expectation before. This time, he does it as the clear No. 1 seed in New York, with the draw starting to thin and the stakes rising. Darderi, seeded No. 21, has nothing like that pressure. That makes him dangerous.
If Zverev wants to keep control of this tournament, he has to keep control of this night.
Men’s fourth round: the undercard with bite
Before Zverev and Darderi, three men’s matches shape the rest of the quarterfinal picture.
At 1 p.m., No. 24 Francisco Cerundolo meets No. 28 Alexander Blockx in a battle that promises long rallies and fine margins. At 4 p.m., No. 14 Learner Tien faces Karen Khachanov, a seasoned major performer who knows how to navigate these rounds.
At 4:30 p.m., Arthur Gea takes on Botic van de Zandschulp, a player who has already authored deep runs in New York and tends to thrive in chaos. It’s the kind of match that can suddenly steal attention if the scoreline tightens.
How to follow Monday’s action
Play begins at 11 a.m. ET, with coverage on ESPN and ABC. Every match is also available via ESPN Unlimited and Fubo, with start times listed in Eastern and subject to late tweaks, as always at a Slam.
Scores from both the women’s and men’s fourth rounds will start to roll in as the day session gets underway and the night session builds toward Gauff and Zverev.
Tuesday’s quarterfinals already set
While Monday decides the rest of the last eight, Tuesday already has a blockbuster feel.
In the women’s quarterfinals, world No. 1 Aryna Sabalenka faces No. 6 Linda Noskova, a rising threat with nothing to lose against the top seed. No. 3 Jessica Pegula, chasing a long-awaited deep run at her home major, meets No. 26 Emma Navarro in an all-American showdown.
The men’s quarterfinal lineup is just as sharp. No. 2 Carlos Alcaraz, the sport’s electric standard-bearer, clashes with No. 8 Ben Shelton, whose game and personality seem built for New York noise. No. 11 Frances Tiafoe then takes on Alex Michelsen in another all-American duel that will say plenty about the immediate future of US men’s tennis.
Monday will decide who joins them. Under the lights, under pressure, with the second week looming, this is where the 2026 US Open stops being a bracket and starts becoming a story.
