US Open: where Zverev's draw really breaks

Alexander Zverev enters Flushing Meadows as the No. 1 seed, an inheritance from the withdrawal of Jannik Sinner, sidelined on August 21 by a right knee problem. The path the draw hands him is the softest among the top eight: Lorenzo Sonego in the opener, Alejandro Tabilo (25) projected for the third round, Lorenzo Musetti (13) in the round of 16, Alex de Minaur (6) in the quarterfinals. This year, serve has never been Zverev's problem, and in a draw like this it won't be here either. How far he goes depends on the other half of his tennis: what he does when he's the one who has to return.

Serve holds, the break comes late

On hard courts Zverev's serve produces matches that stay balanced until the end: few break points in question on either side, sets that slide toward the tie-break, margins reduced to a handful of points.

The problem is symmetric. If he can't break serve, the match comes down to two or three isolated points, and there variance decides.

His last two hard-court defeats have exactly the same shape. In Montreal he won the first set against Tallon Griekspoor in a tie-break and then lost 7-6(3), 2-6, 4-6. In Cincinnati, in the round of 16, he won the first set against Tommy Paul and lost 6-4, 6-7, 4-6. In both cases he took the first set home and lost the next two. In both cases he failed to convert when his opponent dropped off.

Five sets give him back that margin. In 2026 at Slam level he made the semifinal in Melbourne, won Roland Garros against Flavio Cobolli in four hours and sixteen minutes, and reached the final at Wimbledon. Over the long distance his model works; over three sets it falls apart.

The Musetti round of 16 is the real turning point

The round of 16 is the first point where the draw asks him something serve alone doesn't solve. Musetti leads 3-2 in their head-to-head, though the most recent meeting, in Vienna in 2025, went to Zverev 6-4, 7-5 on indoor hard.

The Italian arrives off a Cincinnati quarterfinal, where he lost only to Frances Tiafoe. His game is the kind that has historically troubled Zverev more than a flat hitter: slice backhand, changes of rhythm, drop shots, everything that stops the German from finding the repeated trajectory he builds points around. Against an opponent who hits flat, Zverev wins the grinding rallies. Against someone who breaks up that rhythm, he has to take risks he doesn't like.

Before that come Tabilo and, in the same quarter, Rafael Jodar (12) and Casper Ruud (19) as possible quarterfinal opponents if de Minaur doesn't hold his seeding.

de Minaur in the quarterfinals is the most readable round

The projected quarterfinal is, paradoxically, the least dangerous of the three final passages. The German leads 8-3 in their head-to-head, and the reason is structural: de Minaur doesn't have a serve that gives him free points, so every one of his service games stays open in a way Zverev's don't. On hard courts and over best-of-five, the Australian has to build every break from the back of the court against one of the least attackable serves on tour, and he doesn't have the power to shorten rallies when the match stretches out.

The semifinal is another matter. Felix Auger-Aliassime (3) still looms over his half of the draw and is the player who eliminated Zverev in the third round of the 2025 US Open in four sets, before beating him again at the Turin Finals 6-4, 7-6(4). The Canadian closes out points early and takes away the one terrain where Zverev has a structural advantage: rally length.

The forecast and the condition that overturns it

Zverev is a clear favorite through the quarterfinals, and stays the favorite against de Minaur: the round of 16 against Musetti is where he's most at risk, not the quarterfinal. The semifinal against Auger-Aliassime is the match that decides whether this draw is worth a final, and there the two are close.

The condition that flips everything is measurable as early as the third round: if Zverev's first-serve percentage drops below 65%, his one structural edge disappears and every set becomes a tie-break. Also worth watching: the number of sets played before the round of 16. If he racks up more than twelve, he'll arrive against Musetti with the wrong legs for a match of broken rhythm.
