US Open Thursday: Zverev nearly made history, Badosa faces scheduling disadvantage, and signals from the data

Alexander Zverev walked into the press room with a pale face. Hours earlier, he had just escaped a historic shock: beating Lorenzo Sonego in a tense 5-set match, with a score so close that if he had lost, he would have become the first No. 1 seed to lose in the first round of a men's Grand Slam since 2026. That number haunts me not only for its historical significance, but because it exposes an undeniable truth: the German's body and form are hanging on a fragile line. Thursday's play at the 2026 US Open did not begin with a match, but with a schedule cleanup due to rain. Many first-round matches postponed from Tuesday and Wednesday were pushed into Thursday, creating a congested day. Paula Badosa is a typical victim: she had to play two consecutive days, a major physical disadvantage before her night match against Cori Gauff, the 2026 champion. Meanwhile, Alex Eala, the 20-year-old Filipino, was seeded 17th at a Grand Slam for the first time, an unprecedented milestone in her country's tennis history. And in doubles, the Williams sisters could return on Friday, opening an emotional farewell story. Zverev's match against Sonego was the biggest risk signal of the day. A No. 1 seed should cruise through the first round, but needing 5 sets to overcome an opponent outside the top 50 shows instability. Data I have tracked since the beginning of the season shows Zverev tends to start slowly in major tournaments, but never this slowly, almost losing. He saved only one match point before turning things around. This raises questions about his stamina and focus - two decisive factors in a two-week Grand Slam. For Badosa, playing two consecutive days is not just a physical issue. Recovery science shows that rest time between matches under 24 hours decreases first-serve percentage by 3-5% and significantly increases unforced errors. Gauff, who had an extra day off, will have a clear advantage. I have witnessed many similar cases in rain-disrupted tournaments: players with congested schedules often lose precision in decisive games. Alex Eala is the most positive story of the day. Her No. 17 seeding is not a gift - it is the result of a remarkable season, with wins over top-30 players. But what I care about is how she handles the pressure of entering a Grand Slam with such a high seeding for the first time. Experience shows that young players are often overwhelmed by big courts and expectations, and Eala will need to control her emotions in her first match. As for Monfils, his win on his 40th birthday is a memorable moment. But from a data perspective, this win does not carry much professional significance if his opponent was not in the top 50. What matters is his next match: facing No. 14 seed Learner Tien, a rising young player. Monfils will have to rely on experience and wisdom rather than speed - something no longer at its peak. Many will rush to conclude that Zverev is weak, Badosa is disadvantaged, and Monfils is at the end of his career. But I see it differently. Zverev's 5-set match could be the necessary medicine for him to rediscover his rhythm - many Grand Slam champions have won such long matches in the first round and then exploded. For Badosa, playing continuously could help her maintain momentum, as long as she manages her energy wisely. As for Monfils, I do not see this as a sad farewell, but as a final performance full of pride. This US Open is witnessing an intersection between the old and new generations. The signals from Thursday's schedule will shape the tournament's landscape, but for me, the most important thing is how each player manages their physical and mental state. As I often say: 'Every pain is a map; only the patient can read the full ink it leaves.' And 'Data does not lie, but the body always knows how to hide illness.' In this context, the night match between Gauff and Badosa will be the first test for both. Gauff needs to defend her 2,000 champion points from last year, no small pressure. Badosa, despite fatigue, can still surprise if she maintains focus. I will closely monitor the serve stats and unforced errors of both - these numbers will speak louder than any prediction. And in doubles, the Williams sisters' appearance on Friday will be a historic moment. Even if they lose in the first round, its symbolic value far exceeds the result. It is a reminder that tennis is not just about numbers, but also about stories. Looking back at Thursday's entire schedule, I notice a recurring theme: the fragility of physical and mental strength in a rain-disrupted tournament. Zverev almost lost due to lack of match rhythm. Badosa pays the price for a congested schedule. Eala faces unprecedented pressure. Monfils is trying to prolong his career with willpower. All are signals that data can decode, if we are willing to listen. I will continue to follow the next matches, especially how Zverev handles his match against Halys, and whether Badosa can overcome Gauff in her under-rested state. Each match is a piece of the puzzle, and only when all pieces are assembled will the full picture of US Open 2026 become clear.
