Novak Djokovic's Shocking US Open Exit to Mariano Navone

Under the Ashe lights where he has ruled for a generation, Novak Djokovic finally looked mortal.

The 24-time major champion staggered through illness, cramps and a blizzard of errors on Sunday night, then watched a player who grew up idolizing him slam the door on his US Open. Mariano Navone, unfazed by the stage and the legend across the net, outlasted Djokovic 7-6 (5), 5-7, 4-6, 6-2, 6-1 in a four-hour, 36-minute epic that felt, at times, like a farewell.

It was the longest opening match of Djokovic’s Grand Slam career. It was also his earliest exit at a major in 20 years, dating back to the 2006 Australian Open. He had never before lost in the first round of the US Open.

On the 21st anniversary of his debut in New York, the question hung in the humid night air: was this his last match here — or at any Slam?

A champion’s body betrays him

From the start, something was off.

Djokovic, the No. 4 seed, jumped to 3-0 and 4-1 leads in the first set, the kind of early chokehold that has broken countless opponents on this court. Then the errors began to drip, then pour. The rhythm vanished. The timing deserted him.

By the end, the numbers told a brutal story: 70 unforced errors from one of the sport’s great metronomes.

His body offered its own commentary. Djokovic threw up at least once. He grabbed at his left foot, clearly bothered. A doctor delivered pills courtside. During a medical timeout between the fourth and fifth sets, he lay face down as his lower back was massaged. On several strokes he grimaced, the strain etched across his face.

Across the net, Navone did not blink.

Navone’s night

For the 25-year-old Argentine, this was the kind of night he had imagined as a kid, watching Djokovic dominate the sport.

“(It) was very tough for me because you are playing with the ‘GOAT’ on this court,” Navone said on court, still processing what he had done. “For sure it’s the best thing I’ve had on court. This is an amazing court and the biggest stage. It’s amazing, the way we play. I mean, five sets. … I’m very happy. I don’t know. What can I say?”

He had already won his first ATP singles title earlier this year. This, though, was another level entirely: five sets against the most decorated player in tennis history, under the lights, with the world watching.

The moment never swallowed him. When Djokovic clawed back, Navone steadied. When the match seemed to tilt toward the champion, Navone found more.

“It’s unbelievable,” he said. “This means a lot. It’s a dream come true.”

Flickers of the old Novak

For all the physical strain, there were still flashes of the old Djokovic.

With his wife, Jelena, watching with a worried gaze from the stands, he occasionally looked like the man who has defined this era. He tightened his game to take the second set, punctuating it with a rare, controlled fist pump. He fed off the Ashe crowd in the third, cupping his hand to his ear and gesturing for more noise as he surged ahead.

The comeback felt familiar: Djokovic down, Djokovic hurting, Djokovic somehow solving the puzzle and breaking an opponent’s will over five sets. He has done it 42 times in his career.

This time, the script flipped.

After firing a shot wide in the fourth set, Djokovic landed awkwardly and dropped his racket, a small, telling surrender to the night. The fourth set slipped away. The fifth never really started for him. Navone raced through it, while Djokovic’s legs and timing deserted him for good.

What would have been his 43rd five-set win became Navone’s first.

A brutal stretch, and a clouded future

The loss capped a rough summer swing. Djokovic had arrived in New York already searching for answers after a first-round defeat at the hardcourt event in Cincinnati, his first match since losing to world No. 1 Jannik Sinner in the Wimbledon semifinals.

He had tried to spin that early Cincinnati exit as a blessing — more time to prepare, more time to heal. At the same time, he admitted that opening matches have grown trickier in recent years, that finding his level from the first ball is no longer a given.

On Sunday, that concern came to life in the harshest possible way. He did not overcome the hurdle. He never quite found his game. Instead, under the lights that have framed so many of his greatest nights, he was left to confront something entirely different: an uncertain horizon.

For Navone, this was the breakthrough of a lifetime.

For Djokovic, it felt like the night when time, finally, refused to bend.
