The US Open bottom half was built around two champions, and one of them lasted a single match.xNovak Djokovic‘s 7-6(5), 5-7, 4-6, 6-2, 6-1 loss to Mariano Navone on Sunday night removed the fourth seed from a section that pre-tournament previews had repeatedly identified as the deepest in the draw.
The four-hour, 36-minute defeat was Djokovic’s first at the opening stage in New York and his first in the first round of any major since the 2006 Australian Open, ending a run of 78 consecutive Grand Slam first-round wins.xThe result matters beyond the scoreline. Draws are structural documents, and removing a top-four seed at the first opportunity changes the arithmetic for everyone drawn beneath him.
What the section held. Djokovic’s quarter was assembled with four former US Open champions in it: Djokovic himself, seventh seed Daniil Medvedev, 2014 winner Marin Cilic and 2016 winner Stan Wawrinka, the last of whom entered on a reallocated wild card for the final Grand Slam of his career. Frances Tiafoe at No. 11 and Brandon Nakashima at No. 16 filled out the seeded resistance. With Djokovic gone, Medvedev is the highest-ranked seed left in the quarter.
Why nobody is promoted. A seed lost on court is not replaced. The Grand Slam Rule Book provides for reallocation only when a seed withdraws — before the order of play for day one is released, a vacancy among seeds one to four promotes the fifth seed upward and pulls the 17th seed into the gap; after that release, the position goes to a lucky loser. None of that machinery applies here. Navone simply occupies the line, and the section keeps its shape with a No. 49 in the position a No. 4 was drawn into.
The second-round consequence. The winner of the Matteo Berrettini–Wawrinka opener was drawn to meet Djokovic next. That assignment is now Navone, an Argentine whose record is built on clay — he won his maiden ATP title on the surface in Bucharest this year — and who had won one prior US Open main-draw match before Sunday. The most anticipated second-round fixture in the bottom half became one of its most open.
Further up the sheet. Medvedev, who opened with a straight-sets win over Hugo Gaston, was Djokovic’s projected quarterfinal opponent and now has the section’s clearest path to the last eight. Nakashima was the projected fourth-round obstacle. Beyond that, the draw had Djokovic meeting Carlos Alcaraz in the semifinals, a rematch of last year’s meeting in New York; whoever emerges from this quarter will arrive there with a considerably thinner resume.
What it does not change. Alcaraz’s own route is untouched. The defending champion is still drawn to face eighth seed Ben Shelton or Cincinnati champion Arthur Fils in the quarterfinals, and his section carries 15th seed Alexander Bublik in the fourth round. The bottom half lost its second marquee name, not its first.
Djokovic, who turned 39 in May, offered no timeline afterward. Tennis Majors reported he is expected to drop out of the top 10 for the first time in eight years. The ranking consequence is real, but the draw consequence landed first, and it landed on eight other men.
