Zverev beats Darderi in straight sets at US Open 2026, becomes the only man to reach the quarter-finals of all four Grand Slams

New York – Alexander Zverev answered questions about his fitness with a straight-sets win over Luciano Darderi in the fourth round of the 2026 US Open. The 6-2, 6-2, 7-6(3) scoreline on Arthur Ashe Stadium not only sent the German into the quarter-finals, but also gave him a rare milestone: he is the only man this season to reach the quarter-finals of all four Grand Slams. A closer look at the match, however, shows that it was not entirely one-way traffic. The third set was where Darderi found a way to trouble Zverev, and it took Zverev’s composure in the tiebreak to close out the match. Zverev arrived at this match with questions about his form. He had a slow start to the tournament and played two five-set matches before reaching the fourth round. His goal, therefore, was not only to win, but to win as quickly as possible. In the first two sets, Zverev executed a clear game plan: solid serving, deep returns, and no long baseline rhythm for Darderi. He held his serve under pressure late in the first set, then raised his level on return in the second. When Darderi missed a drop shot, Zverev immediately converted the chance for a second break and moved 4-0 ahead. Darderi, the 21st seed from Italy, was not an easy player to subdue. The third set saw a clear tactical shift. Instead of trying to beat Zverev from the baseline, Darderi used a powerful first serve and well-timed drop shots to disrupt Zverev’s movement. That approach took away Zverev’s rhythm and forced the German to cover more ground. The set went to a tiebreak, turning the match into a genuine test of nerve. Zverev passed that test. He won the tiebreak 7-3, a score that reflected sharp focus rather than luck. At the highest level, top players are not always at their best. What separates them is the ability to play well enough at the most important moments. Zverev did exactly that against Darderi. He did not need too many spectacular shots; he simply stayed accurate whenever the match was in the balance. The win also allowed Zverev to put the slow-start narrative behind him for now. But it did not fully solve the physical question. Two earlier five-set matches had already taken a toll. At 29, recovery between matches is no longer as quick as it was in his early twenties. Scheduling is another factor: Zverev just played his fourth consecutive night session in New York. A consistent time slot can help rhythm, but accumulated fatigue remains a quiet threat in the second week of a major. Zverev’s next opponent is Botic van de Zandschulp of the Netherlands. Any player who reaches a Grand Slam quarter-final must be taken seriously, regardless of ranking or reputation. Van de Zandschulp will enter the match with nothing to lose, while Zverev will carry the pressure of being a French Open champion and one of the main title contenders at this US Open. Overall, the win over Darderi gave Zverev more than a place in the last eight. It gave him a statement about his ability to manage a mid-match crisis. If Zverev stays as calm as he did in the tiebreak, and if his body allows him to keep serving aggressively, he has every reason to aim for a second Grand Slam title. If the miles from earlier rounds make his legs heavy, however, the remaining opponents will know how to exploit that weakness, just as Darderi did in the third set. The biggest question for Zverev at the 2026 US Open is no longer form. He answered that with three convincing sets against a seeded player. The real question is whether his body can hold up until the final. A Grand Slam is always a test of skill, tactics, and endurance. At 29, Zverev is showing that the skill and tactical parts are still working well. The physical part remains the biggest unknown, and only the matches ahead will provide the answer.
