Zverev wins again after 2 AM at the US Open: When the Roland Garros champion becomes a survivor

New York night, 2:15 AM. Arthur Ashe Stadium lights still on, and Alexander Zverev has just finished his second consecutive five-set match. This time, his opponent was Quentin Halys, the world No. 52. The match lasted 4 hours and 33 minutes. When I saw that number on the screen, I remembered a line I once wrote after that night at Anfield: "At Anfield that night, I stopped counting numbers to listen to the ghosts whisper." Here, the ghosts whisper about fatigue, about a champion trying to hold himself together amid the vortex of expectations. Zverev, the No. 1 seed at this year's US Open, defeated Halys 6-4, 6-7(5), 6-1, 6-7(3), 7-5. But this victory does not carry the hallmark of a title contender. It carries the hallmark of a survivor. This is the first time in the Open Era that a No. 1 seed has had to play two consecutive five-set matches in the first two rounds. I have followed tennis for nearly four decades, and I can say this: this number is not just a coincidence. It is a signal. Let me set the context. Zverev arrived in New York as the reigning 2026 Roland Garros champion. He is the world No. 2, the top seed at this tournament. But from the very first round, against Lorenzo Sonego, an unseeded player, Zverev needed five sets. He admitted after the match: "Being introduced as the number one seed... is great, until you almost lose every match." That is a rare quote showing honesty about his own form. He also revealed that he could not sleep until 5 AM after the Sonego match. When I read that, I immediately thought of a principle I learned from my time as a data consultant for Liverpool: sleep is part of tactics. If you don't sleep, you can't recover. If you don't recover, you can't perform at your highest level. Technically, Zverev possesses one of the best serves on tour, along with one of the heaviest two-handed backhands. These are ultimate weapons for hard courts. But what is happening? Against Halys, two of the first four sets went to tiebreaks, splitting 1-1. This shows that Zverev's baseline control is still excellent, but his ability to convert that control into quick holds or decisive breaks is inconsistent. I have watched many of Zverev's matches, and I notice a pattern: he controls the tempo, but lets his opponent drag him into long battles. This is inefficient, especially in the hot and humid conditions of New York. My data from this season shows a concerning disparity. Zverev's second-round match lasted 4 hours and 33 minutes. On average, a three-set hard-court match on the ATP Tour lasts about 2 hours and 15 minutes. Playing two consecutive five-set matches, with a total on-court time of over 8 hours, is a massive physical burden. And the notable thing is that his opponents — Sonego and Halys — are both outside the top 50. This is not a tough draw. This is a form crisis. But here, I want to offer a contrarian view. Many will say that winning two consecutive five-set matches shows Zverev's grit and fitness. But I don't think so. I think this is a tactical red flag. Zverev's game is built on a powerful serve and heavy baseline shots. This style is designed to finish matches efficiently on hard courts. Needing 4 hours and 33 minutes to get past the world No. 52 suggests one of two things: either Halys served exceptionally well, or Zverev was passive in his movement and point construction. Given that Zverev himself admitted his form is poor, the second possibility seems more likely. Look at what is happening around him. Sinner withdrew due to injury. Alcaraz, a 7-time Grand Slam champion, is playing below his best. Musetti retired due to physical issues. De Minaur lost to van de Zandschulp, an unseeded player. Zverev's quarter of the draw has opened up in an extraordinary way. Only 6 players remaining in the field have Grand Slam final experience, and only 3 have won a major. This is the clearest opportunity for Zverev to capture his second Grand Slam title. But this very opportunity creates a psychological trap. When the draw opens up, expectations rise. And if Zverev loses early, the narrative will be "a missed opportunity" — an invisible pressure weighing on the shoulders of a man already struggling with himself. I remember a principle in data analysis: correlation is not causation. An open draw does not automatically bring victory. It only creates favorable conditions. And favorable conditions mean nothing if the body cannot recover. In the third round, Zverev will face Alejandro Tabilo, the world No. 25. Zverev has never lost to Tabilo in their head-to-head. But Tabilo is a left-handed player with a big lefty serve — a stylistic matchup that can be awkward even when the head-to-head favors Zverev. With accumulated fatigue, this is the most dangerous "should-win" match of the tournament for Zverev. I have witnessed too many cases where a fatigued player loses a match that the head-to-head says they should win. And then there is the scheduling issue. Zverev's match ended at 2:15 AM. This is a systemic problem at the US Open — night sessions frequently extend past midnight. Research on athlete circadian rhythms suggests that sleep disruption can reduce performance by 5-15%. For a man who has already played two consecutive five-set matches, this is an invisible handicap that no statistic can offset. I also want to mention another detail in the article: the retirement of Gael Monfils. At 39, Monfils announced his retirement after this US Open. He has signed a contract with an asset management company in Switzerland to prepare for life after tennis. This is a rare model of future planning in the sports world. And his departure, along with the draw being depleted of champions, marks a transition point for men's tennis: from the era of legends to a more open and unpredictable period. Back to Zverev. The biggest question is not whether he can win this tournament. The biggest question is whether his body can endure four more matches at similar intensity. I am too old to believe in miracles, but young enough to know which miracles can be measured. And the data is saying: Zverev is in a danger zone. He needs a quick match in the third round, not another five-set battle. He needs to finish before midnight, not at 2 AM. He needs a convincing victory to rebuild confidence, not another struggle to survive. When the stands are empty, the numbers begin to learn to sing. And their song right now is a sad melody about fatigue, about pressure, and about a champion trying to find himself amid the glitter of New York. Can Zverev turn this story into a redemption arc? Or will it become an obituary for a missed opportunity? I don't have the answer. But I know that, in the world of data, nothing is certain — only probabilities that are shifting every hour, every minute, every sleep. What I could be wrong about: Maybe Zverev is deliberately extending matches to build fitness for later rounds. Maybe he is testing a new tactic. But I don't think so. When a player says he "almost loses every match," that is not tactics. That is truth.
