Alexander Zverev’s 2026 US Open campaign has been a rollercoaster of epic proportions. The No. 1 seed has already spent more than nine hours on court across his first two matches, surviving back-to-back five-set marathons before finding his rhythm against Alejandro Tabilo. Now, the French Open champion stands just one win away from the quarterfinals at Flushing Meadows.
Standing in his path is No. 21 seed Luciano Darderi, the Italian who stunned Zverev at the Rome Masters earlier this year—saving four match points in a dramatic comeback victory. The stakes could not be higher for the 29-year-old German, who is chasing his second Grand Slam title of 2026 after finally breaking through at Roland Garros.
The road to the fourth round has been anything but straightforward for the top seed. Zverev opened his tournament with a grueling five-set battle against Italy’s Lorenzo Sonego, spending over four hours on court. He followed that with another five-set epic against Quentin Halys, pushing his total court time to a staggering nine hours and 26 minutes.
That workload represented the most time a top seed had needed to reach the third round of a major since 1999. Speaking after his third-round victory, Zverev acknowledged the challenge with characteristic dry humor: “My coach was actually quite smart—he explained to me a best of five set match doesn’t mean you have to play five sets.”
Against Tabilo, the German finally delivered a statement performance. The 6-2, 7-6(2), 6-2 victory on Arthur Ashe Stadium showed the Zverev that fans expected from the tournament’s top seed. He didn’t face a break point in the first set, winning all 11 points behind his first serve. Though Tabilo pushed back in the second set, forcing a tiebreak and saving two set points, Zverev’s composure never wavered.
“I am definitely happy with the improvements,” Zverev said after the match. “I spent 10 hours on the court in two matches so I had to find my rhythm somehow, and I did.”
Zverev arrived at the US Open as the tournament’s top seed following the withdrawal of world No. 1 Jannik Sinner due to injury. The German, ranked No. 2 in the world, was elevated to the top seeding position. Defending champion Carlos Alcaraz is seeded second in the bottom half of the draw.
The seeding reflects Zverev’s remarkable transformation in 2026. After years of being labeled tennis’s “nearly man,” he has finally delivered on his immense potential. His consistent performance throughout the season, particularly at the Grand Slams, made him the logical choice to lead the draw in Sinner’s absence.
The 2026 season has been a career-defining year for Alexander Zverev.
Zverev finally broke his Grand Slam duck at Roland Garros, claiming his first major title. The victory ended years of heartbreak, including his agonizing five-set loss to Dominic Thiem in the 2020 US Open final and defeats in the 2024 French Open and 2025 Australian Open finals.
He defeated Flavio Cobolli in a five-set final, finally silencing doubts about whether he could win the biggest titles. “Now finally it’s a happy end,” Zverev said after the match.
The confidence from Paris carried through to the grass courts of Wimbledon. Zverev reached his first final at the All England Club, becoming only the seventh man in the Open era to win the French Open and reach the Wimbledon final in the same season. He ultimately fell to Jannik Sinner in four sets, but his performance confirmed his arrival as a genuine force across all surfaces.
Now Zverev has the opportunity to add a second Grand Slam title to his 2026 resume. His 2020 runner-up finish at Flushing Meadows remains his only previous final appearance in New York. A victory here would establish him as the dominant player of the season.
The fourth-round matchup against Luciano Darderi carries significant weight. The two have met twice previously, both at the Italian Open in Rome, with each player claiming one victory.
Their most recent encounter in May 2026 at the Internazionali BNL d’Italia was a classic. Darderi saved four match points to stun Zverev in the fourth round, a result that shocked the tennis world. The Italian came back from a set down to win 1-6, 7-6(10), 6-0.
Zverev’s earlier victory over Darderi came in 2024 in Rome, 7-6(3), 6-2. This will be their first meeting on hard courts and their first at a Grand Slam tournament.
Darderi, 24, has enjoyed a breakout season. He has reached a career-high ranking and entered the US Open as the 25th seed. He advanced to the fourth round at the Australian Open earlier this year, marking his first Grand Slam fourth-round appearance. Now at Flushing Meadows, he has matched that achievement and is looking to go one better.
The Italian has been impressive in New York, dropping only one set in his first three matches. He defeated Harry Wendelken, Dalibor Svrcina, and Australian wild card Dane Sweeny to set up this blockbuster clash.
The possibility is very real. Zverev has already proven he can win a major, and his Wimbledon final run demonstrated his ability to compete at the highest level consistently. The US Open draw has opened up favorably, though Darderi represents a dangerous opponent.
What works in Zverev’s favor is his experience. He has been in this position before, reaching the 2020 US Open final and more recent major finals. The mental hurdle of winning a first Grand Slam is behind him. The physical challenge, however, cannot be ignored. Nine hours and 26 minutes of tennis in the first two rounds is a significant toll.
Zverev’s game is built for hard-court tennis. His serve is one of the most formidable in the game, capable of winning him free points and bailing him out of difficult situations. Against Tabilo, he demonstrated his first-strike capability, dominating behind his first serve and applying relentless pressure from the baseline.
His backhand remains one of the best on tour, a consistent weapon that allows him to dictate rallies from the baseline. His movement for a player of his height is exceptional, making him a difficult player to hit through.
Perhaps most importantly, Zverev has developed mental resilience. His Grand Slam breakthrough has transformed his belief. After years of coming up short, he now knows he can win the biggest matches.
The nine hours and 26 minutes Zverev spent on court in his first two matches is a significant concern heading into the second week. While his straight-sets win over Tabilo provided some relief, the cumulative fatigue could become a factor in longer matches.
Zverev’s Wimbledon final was impacted by a knee injury sustained during the match. He slipped and overextended his knee, hampering his serve and movement. The German has shown no signs of physical issues in New York, but the workload is a consideration.
Recovery becomes increasingly important in a Grand Slam. With his fourth-round match against Darderi, Zverev will need to manage his energy levels carefully if he hopes to mount a deep run.
Zverev faces Luciano Darderi in the fourth round with a quarterfinal berth on the line. A victory would pit him against the winner of a match that includes players like Alex de Minaur, potentially setting up a quarterfinal showdown with the Australian sixth seed.
The draw has been kind to Zverev in some respects, with Jannik Sinner absent and Carlos Alcaraz in the opposite half. However, the depth of men’s tennis means no match is easy. Darderi has already proven he can beat Zverev, and the Italian will enter this match with confidence.
Zverev’s best US Open result came in 2020, when he reached the final but fell to Dominic Thiem after leading two sets to love. It was a devastating defeat that would shape the narrative of his career for years.
He had never been past the fourth round at Wimbledon before 2026, making his runner-up finish even more remarkable. His French Open victory represents his only Grand Slam title, though he has also reached finals at the Australian Open (2025) and the US Open (2020).
For Zverev, the goal is no longer just to win one Grand Slam. He has set his sights on establishing himself as part of a new Big Three alongside Sinner and Alcaraz. “I think I’ve been pushing those guys,” he said after Wimbledon. “I haven’t beaten them this year, but I’ve pushed them to the limits.”
Zverev’s journey at the 2026 US Open encapsulates everything that makes Grand Slam tennis compelling. There is the No. 1 seed status, earned through a career-best season. There are the marathon matches that tested his physical and mental limits. There is the Darderi revenge narrative, with the Italian having saved four match points to beat him in Rome.
Most importantly, there is the possibility of history. A second Grand Slam title in 2026 would cement Zverev’s place among the game’s elite. It would confirm that his French Open victory was not a one-off, but the beginning of a new chapter.
