After enduring grueling five-set marathons earlier in the tournament, the German star secured a straight-set victory at Arthur Ashe Stadium.
Overcoming the Late-Night Marathon Trend
The scheduling at Flushing Meadows had tested endurance through a series of late finishes across the opening week. Alexander Zverev had spent hours on the grounds in Queens during his first two rounds, requiring nine and a half hours total to eliminate Lorenzo Sonego and Quentin Halys. Because an earlier women’s singles match between Iva Jovic and Alexandra Eala stretched past three hours, Zverev did not step onto the court until 22:35 local time, raising concerns about another exhausting night shift.
Instead of another five-set thriller, the 29-year-old German broke that exhausting pattern. He broke serve twice early to claim the opening set in just 38 minutes, utilizing a high first-serve conversion rate where he won every single point when his first delivery landed in.
Frustration and a Brief Third-Set Flare-Up
Alejandro Tabilo struggled to find a foothold in the largest tennis stadium in the world. As the second set drew to a close, Zverev experienced a minor dip in concentration, surrendering a service game after a double fault. Tabilo pushed the set into a tiebreak, but unforced errors from the Chilean allowed Zverev to take a two-set lead.
Annoyed by his own mistakes in the early stages of the third set, Zverev flung his racquet toward the back wall behind the baseline. Despite the brief outburst of frustration, the outcome remained secure.
Humor and Self-Irony After the Match
Alexander Zverev explained via Frankfurter Allgemeine Zeitung that his coach had told him a best-of-five match does not mean you actually have to play five sets.
Reflecting on his physical condition and preparation, Zverev noted that he had practiced for only one hour on Friday because he had spent ten hours on court during his opening two matches. He added that while his performance is heading in the proper direction, room for improvement remains as the tournament progresses.
Shifting Landscape in the US Open Draw
Zverev’s path toward his second Grand Slam title has opened up significantly following a wave of exits among top contenders. As the reigning French Open champion, Zverev extended his winning streak against left-handed opponents to 16 matches, having practiced with his left-handed brother Mischa ahead of the fixture. Meanwhile, the draw lost several major seeds.

American rival Taylor Fritz and Italian finalist Flavio Cobolli were eliminated on Saturday. Those departures followed earlier exits by third-seeded Félix Auger-Aliassime, Novak Djokovic, and an absent world number one, Jannik Sinner, who missed the event due to injury.
Next Challenge in the Round of Sixteen
He advances to face 21st-seeded Italian player Luciano Darderi.
Darderi booked his spot in the fourth round by defeating Harry Wendelken, Dalibor Svrčina, and Dane Sweeny. In their previous head-to-head history, Zverev and Darderi have split two prior meetings, with each player claiming one victory.
