Novak Djokovic’s 2026 US Open campaign ended in a way few tennis fans could have imagined. The 39-year-old Serbian great was beaten by Argentina’s Mariano Navone in a dramatic five-set first-round contest at Arthur Ashe Stadium, bringing his latest attempt at a record 25th Grand Slam title to an early and painful end.
The final score read 7-6(5), 5-7, 4-6, 6-2, 6-1 in Navone’s favour. But the numbers only tell part of the story. Djokovic spent much of the match battling his own body, dealing with vomiting, cramps, back problems, shoulder trouble and severe fatigue before eventually running out of energy.
For a player who has spent decades producing remarkable comebacks, this was a particularly difficult night. Djokovic managed to turn the match around after losing the opening set, but the physical problems returned with greater force as the contest moved into its final stages.
Djokovic Faces Major Physical Struggle
The warning signs appeared well before the final set. Djokovic looked uncomfortable in the humid New York conditions and repeatedly tried to manage the heat during the match.
At one stage, the Serbian appeared to struggle badly with his stomach and eventually vomited during the contest. Medical assistance followed, with Djokovic receiving treatment and fluids while attempting to remain competitive.
His problems did not stop there. As the match continued, cramps and pain affected his movement, while his back and shoulder also became increasingly troublesome. The situation became particularly damaging to his serve and ability to defend points.
Despite everything, Djokovic refused to simply walk away. He continued fighting and even managed to take control after losing the first set.
That fighting spirit briefly made another Djokovic comeback look possible. It ultimately was not enough.
Mariano Navone Produces Huge Upset
Mariano Navone entered the match as the clear underdog, but the Argentine showed impressive patience throughout the four-hour-plus battle.
The first set went to a tiebreak, where Navone managed to take the early advantage. Djokovic responded strongly, however, winning the second set 7-5 and then taking the third 6-4.
At that stage, the match appeared to be moving toward another famous Djokovic recovery.
Navone had different ideas.
Rather than allowing the opportunity to disappear, the Argentine kept putting pressure on Djokovic. Once Djokovic’s physical condition deteriorated further, Navone became increasingly aggressive and controlled the fourth set 6-2.
The deciding set was even more one-sided. Djokovic could no longer produce the movement and consistency required to challenge Navone, who closed out the fifth set 6-1.
The victory was easily the biggest result of Navone’s career and came on one of tennis’s biggest stages. The official tournament report confirmed that the win ended Djokovic’s remarkable record of winning his opening Grand Slam match dating back to 2006.
A Record Streak Finally Ends
Djokovic’s first-round defeat carries huge historical significance.
Before this match, he had won 78 consecutive first-round matches at Grand Slam tournaments. His previous defeat at that stage of a major came at the 2006 Australian Open.
That means his loss to Navone represents his first Grand Slam opening-round defeat in two decades.
It is also Djokovic’s first-ever first-round exit at the US Open.
That makes the result much more than an ordinary upset. Djokovic has repeatedly been one of the safest players in Grand Slam opening rounds, often using the early matches to build momentum before facing tougher opponents later in tournaments.
This time, there was no second round.
His 2026 US Open campaign was over after just one match.
The 25th Grand Slam Dream Ends
Djokovic arrived in New York chasing history once again.
With 24 Grand Slam singles titles already to his name, another major championship would have moved him to 25 and given him the outright record for most Grand Slam singles titles.
Instead, that pursuit ended almost immediately.
The loss is particularly frustrating because Djokovic has still shown that he can compete deep into major tournaments during 2026. His results earlier in the season demonstrated that the champion remains capable of producing high-level tennis when his body cooperates.
The problem against Navone was not simply his tennis level.
It was whether his body could survive the demands of a long five-set match.
For more than four hours, Djokovic attempted to find solutions. He changed tactics, fought through discomfort and continued chasing points even when the situation looked increasingly difficult.
But eventually the physical problems became too significant.
Emotional Scenes At Arthur Ashe
The final moments were difficult to watch for Djokovic supporters.
As Navone moved toward victory in the deciding set, Djokovic became visibly emotional on court. Tears appeared as the reality of the defeat began to sink in.
For one of the most successful competitors in tennis history, the moment showed how much the loss meant.
Djokovic has experienced countless defeats throughout his career, including painful Grand Slam finals and unexpected exits. Yet this one felt different because of everything surrounding it.
He had battled physical problems for hours.
He had recovered from a set down.
He had been within touching distance of another comeback.
Then his body simply could not keep going at the same level.
The New York crowd continued to support him during the closing stages, giving the Serbian star a warm reception despite the disappointing result.
What Djokovic Said After Loss
The Serbian later acknowledged just how difficult the physical situation had become.
He explained that vomiting was part of a broader problem involving his body, with cramps and pain eventually affecting his back and shoulder. He also indicated that similar physical difficulties had been troubling him during matches this season.
That admission adds another layer to the defeat.
This was not simply a case of Djokovic playing badly against an opponent ranked lower than him. He was trying to compete while dealing with serious physical discomfort, and the longer the match continued, the harder it became for him to maintain his normal level.
His comments also created fresh questions about his future.
At 39, Djokovic remains one of the biggest names in world tennis, but the physical demands of best-of-five-set Grand Slam matches are becoming increasingly important.
Questions Now Surround Djokovic’s Future
The immediate question is not whether Djokovic still has the tennis ability to beat top opponents.
He clearly does.
The bigger concern is whether his body can consistently handle the demands required to win seven matches at a Grand Slam.
Djokovic himself has expressed uncertainty about how much longer he can continue dealing with recurring physical problems. That does not automatically mean retirement is imminent, but his comments have naturally encouraged speculation about what comes next.
His defeat also comes after a season in which fitness and physical condition have remained recurring talking points.
For Djokovic, the priority now appears to be understanding what is happening physically rather than immediately thinking about another tournament.
Navone Celebrates Career-Defining Victory
For Mariano Navone, meanwhile, the night could become one of the defining moments of his career.
Beating Djokovic at Arthur Ashe Stadium is an achievement that most players dream about, and Navone managed to do it after falling behind in the match.
The Argentine did not panic after Djokovic won the second and third sets. Instead, he stayed competitive, waited for opportunities and capitalised when Djokovic’s physical condition deteriorated.
His ability to remain mentally composed was just as important as his tennis.
Against a player with Djokovic’s reputation, it would have been easy for Navone to become overwhelmed by the occasion. Instead, he completed the biggest victory of his career and advanced into the second round.
A Different Chapter Begins In New York
Djokovic’s early US Open exit changes the atmosphere around the tournament immediately.
For years, his name has been almost synonymous with deep Grand Slam runs. Seeing him leave New York after the opening round is therefore a major moment in the 2026 tennis season.
The defeat also shows how unpredictable modern Grand Slam tennis can be. Experience and reputation still matter, but physical condition can completely change the outcome of a match.
Djokovic fought hard, but Navone stayed ready for his opportunity.
The Serbian legend now faces a period of reflection after one of the most emotional losses of his career. Whether this becomes a temporary setback or a sign of a larger change will only become clearer with time.
For now, one fact stands above everything else: Novak Djokovic is out of the 2026 US Open in the first round, while Mariano Navone moves forward after producing a stunning victory over one of tennis’s greatest champions.
Conclusion
Novak Djokovic’s first-round US Open defeat is one of the biggest shocks of the 2026 tennis season. The 39-year-old battled vomiting, cramps, pain and exhaustion during a marathon five-set contest before Mariano Navone completed a remarkable upset. The result ended Djokovic’s 78-match Grand Slam first-round winning streak and stopped his pursuit of a record 25th major title in New York. More importantly, the physical problems and emotional scenes have raised genuine questions about what comes next for the Serbian legend. Djokovic’s career remains extraordinary, but his latest US Open experience shows that even champions of his level cannot escape the demands of time and physical limits.
