Novak Djokovic Stunned in 5-Set US Open Shock
The Novak Djokovic US Open campaign ended in stunning fashion Sunday as the Serbian superstar suffered a five-set defeat to Argentina’s Mariano Navone in the first round at Flushing Meadows.
Navone, an unseeded Argentine, defeated the 23-time Grand Slam champion 7-6(5), 5-7, 4-6, 6-2, 6-1 in a dramatic contest that lasted more than four hours. The result ended Djokovic’s latest attempt to capture a record 25th Grand Slam title. RReuters+1
The defeat was particularly remarkable because Djokovic had not lost his opening match at a Grand Slam tournament for more than two decades. It also represented his earliest US Open exit in his career.
For Navone, meanwhile, the victory was the biggest win of his career and one of the defining moments of the 2026 tournament.
Novak Djokovic US Open Exit Stuns Tennis World
Djokovic entered the tournament with enormous expectations.
At 39, the Serbian remained one of the biggest names in men’s tennis and was still chasing another major championship. His pursuit of a 25th Grand Slam title added another layer of significance to his appearance in New York.
Instead, the campaign lasted only one match.
Navone refused to be intimidated by Djokovic’s reputation. The Argentine stayed competitive through the opening sets before taking control late in the match.
After Djokovic won the third set to move ahead, Navone produced a decisive response. He took the fourth set 6-2 and then dominated the deciding set 6-1.
The turnaround was extraordinary.

Djokovic Battled Physical Problems
The result was not simply a case of Djokovic playing poorly.
The veteran appeared to struggle physically during the contest. Reuters reported that Djokovic vomited during the match and was dealing with back and shoulder problems that affected his serve as the contest progressed. RReuters
Those problems became increasingly visible as the match continued.
Djokovic was able to fight through the early stages and even recover after losing the opening set. But the physical demands of a five-set match eventually appeared to take their toll.
Navone capitalized.
The Argentine continued to make Djokovic work for every point, and once the match reached the fourth set, Navone found another level.
Djokovic’s movement and serve became increasingly vulnerable, while Navone grew more confident.
Mariano Navone Produces the Biggest Win of His Career
For Navone, this was more than an upset.
It was a breakthrough moment on one of tennis’s biggest stages.
The Argentine entered the match as the underdog against one of the most accomplished players in tennis history. Yet he remained composed when the match became difficult.
Navone lost the third set after Djokovic recovered from the opening-set defeat. Many players might have struggled mentally after allowing such an experienced opponent to regain control.
Navone responded differently.
He immediately shifted the momentum in the fourth set and then carried that confidence into the deciding set.
The final score — 6-2, 6-1 across the last two sets — showed just how dramatically the match changed.

A Rare Early Defeat for Djokovic
Djokovic’s first-round loss is significant because of his extraordinary consistency at Grand Slam tournaments.
For years, the Serbian rarely experienced early exits at the majors. His ability to navigate difficult opening rounds became one of the foundations of his record-setting career.
This time, however, the challenge proved too great.
Reports noted that Djokovic had not lost his opening Grand Slam match in roughly 20 years. His last such defeat came at the 2006 Australian Open, making Sunday’s result one of the most unusual losses of his career. УУкраїнські Національні Новини (УНН)+1
The US Open defeat therefore carries significance beyond one tournament.
It raises fresh questions about how much longer Djokovic can maintain his extraordinary level of performance against younger opponents.
The 25th Grand Slam Dream Ends in New York
Djokovic arrived in New York with history still within reach.
His 24 Grand Slam singles titles already put him at the top of the men’s major championship list. A 25th title would have extended that record and created another landmark in one of tennis’s greatest careers.
That opportunity disappeared immediately.
Navone’s victory ended Djokovic’s 2026 US Open campaign before he could even reach the second round.

For Djokovic, the loss will likely be especially frustrating because he had shown throughout his career that he could overcome difficult circumstances.
This time, his physical condition and Navone’s relentless play combined to produce an outcome few expected.
Navone Turns Pressure Into Opportunity
The biggest difference between the players was momentum.
Djokovic won the third set and appeared to have recovered from losing the opening tiebreak. But instead of allowing the match to slip away, Navone increased the pressure.
His performance in the fourth set changed everything.
Navone broke Djokovic’s rhythm and forced the match into a fifth set. Once there, the Argentine showed remarkable composure.
The deciding set quickly moved in Navone’s direction.
At that point, Djokovic was no longer able to summon the level of resistance that has defined so much of his career.
Navone closed out the victory 6-1.
The result was immediately recognized as one of the tournament’s biggest shocks.
What the Loss Means for Djokovic
The immediate consequence is obvious: Djokovic is out of the US Open.
The longer-term implications are less certain.
At 39, every Grand Slam appearance carries additional significance. Djokovic has continued competing at the highest level despite being surrounded by a generation of younger stars.
But physical challenges become increasingly important as athletes age.
The problems he experienced against Navone will therefore attract considerable attention.
Djokovic’s future schedule and his ability to remain healthy will likely become major talking points following the defeat.
The Serbian has previously indicated that he wants to continue competing at major events, but the demands of five-set tennis are unforgiving.
Sunday’s match provided another reminder of that reality.
A New Chapter for Mariano Navone
While Djokovic’s tournament ended in disappointment, Navone’s US Open campaign has suddenly become one of the stories to watch.
Beating Djokovic changes the expectations surrounding a player.
Navone will now enter his next match carrying the confidence that comes from defeating one of the greatest players in tennis history.
The challenge will be maintaining that level.
A major upset can create enormous attention, but following it with another strong performance is often even harder.
Navone has already demonstrated that he can handle pressure against an elite opponent. His next task will be proving that the victory was not a one-night achievement.
The Argentine now has an opportunity to turn an extraordinary upset into a deeper run at a Grand Slam tournament.
Djokovic’s Loss Adds Drama to the 2026 US Open
Djokovic was not the only major name involved in a dramatic opening day.
The first day of the tournament produced several notable results, including Sofia Kenin’s victory over Venus Williams. Other seeded players advanced, while injuries also affected the early draw. RReuters
That made Djokovic’s defeat part of an unusually dramatic start to the tournament.
The US Open is known for producing unexpected results, but an opening-round loss by a player of Djokovic’s stature immediately changes the narrative around the men’s draw.
With Djokovic gone, the path toward the title has become more open for the remaining contenders.
Why This Djokovic Defeat Is Different
Djokovic has experienced major disappointments before.
He has lost Grand Slam finals, suffered unexpected defeats and faced younger opponents determined to establish themselves.
But a first-round US Open loss is different.
The timing is significant.
At this stage of his career, Djokovic is operating with less margin for error. A single difficult draw, physical issue or bad performance can end a tournament before he has time to recover.
That is exactly what happened in New York.
Navone took advantage of the opportunity, while Djokovic’s physical problems made the challenge even more difficult.
The result could become one of the defining matches of the final phase of Djokovic’s career.
What Comes Next for Djokovic?
The immediate focus will shift from the US Open to Djokovic’s health and future plans.
His physical condition will be particularly important after the issues that emerged during the Navone match.
There is no reason to assume that one defeat automatically marks the end of Djokovic’s career. His achievements demonstrate an extraordinary ability to recover from setbacks.
However, the loss does reinforce a growing question in men’s tennis: how long can Djokovic continue competing with the same intensity against players who are considerably younger?
That question will likely follow him into his next tournament.
For now, the answer remains uncertain.
The Bottom Line
The Novak Djokovic US Open story ended far earlier than anyone expected.
Mariano Navone produced a stunning five-set victory, winning 7-6(5), 5-7, 4-6, 6-2, 6-1 and eliminating Djokovic in the first round. RReuters+1
The defeat ended Djokovic’s bid for a record 25th Grand Slam title and marked his earliest US Open exit.
More importantly, the match exposed the physical challenges Djokovic faced during the contest. Reuters reported that he vomited during the match and dealt with back and shoulder problems as the battle progressed. RReuters
For Navone, however, the night could represent a turning point.
He defeated one of the greatest players in tennis history on one of the sport’s biggest stages.
The question now is whether he can build on that extraordinary victory.
As for Djokovic, the loss will inevitably generate questions about his health, his schedule and how much longer he can continue competing at the highest level.
Whatever happens next, the 2026 US Open has already delivered one of its biggest shocks.
