When Mariano Navone stepped onto the Arthur Ashe Stadium court on Sunday, few could have predicted he was about to script the most stunning upset of the tournament’s opening day. Yet the 25-year-old Argentine emerged from a grueling four-hour, 35-minute marathon with a 7-6(5), 5-7, 4-6, 6-2, 6-1 victory that sent shockwaves through the tennis world—not because of what Navone accomplished, but because of what it meant for Novak Djokovic, the sport’s aging titan.
Djokovic's US Open nightmare
For the first time in more than two decades, the 39-year-old Djokovic would not advance from the opening round of a Grand Slam event. The last time this happened was the 2006 Australian Open, a staggering 20-year drought that underscored just how dominant he has remained, even as Father Time catches up. On Sunday, time finally ran out.
From the opening exchanges, something was visibly wrong. Djokovic, who had arrived in New York severely undercooked—having played just once since his Wimbledon semifinal appearance, a loss in Cincinnati—appeared to be wrestling demons beyond mere match rust.
The champion seized early momentum, building a commanding 4-1 advantage in the first set. But as the humidity of the New York summer enveloped the court, so did a mysterious ailment that would define his afternoon. Djokovic began vomiting repeatedly in the corner of the court, his body seemingly in open revolt. He had disclosed before the tournament that he was battling a health condition that flares up in humid climates, but no one anticipated the extent to which it would compromise his performance.
Navone, displaying remarkable poise for a player competing in his first five-set encounter, recognized the opportunity. Rather than attempting to match Djokovic’s power, he extended rallies methodically, forcing the Serbian champion to hunt for winners. The strategy worked. Navone claimed the opening set in a tiebreak that consumed one hour and 15 minutes, signaling early that this would be no pedestrian first-round encounter.
The second set went to Djokovic, and when he also captured the third before breaking for a 2-1 lead in the fourth, a resurrection seemed plausible. This was Djokovic after all—a 24-time Grand Slam champion with a documented ability to dig deeper than any peer when cornered. Yet this was Djokovic at 39, competing on fumes.
As the fourth set progressed, his physical deterioration became impossible to ignore. His back seized. His breathing became labored. He doubled over between points, his body language screaming distress. A medical timeout before the fifth set provided temporary relief but no real remedy. When the final set began, Djokovic looked diminished, visibly fighting back tears as he struggled to generate even moderate pace on his serve.
Navone, sensing the moment, accelerated decisively, reeling off five consecutive games to seize command. When Djokovic improbably cut the deficit to 3-1, briefly threatening an improbable rally, Navone’s nerve held firm. He broke for the sixth time and served out for victory, cementing the greatest achievement of his career.
Navone seizes history
To focus solely on Djokovic’s decline would be to undervalue what Navone accomplished. The Argentine had never won a five-set match in his career before Sunday. He had never advanced beyond the third round at a Slam. Yet he matched Djokovic physically in the early innings and demonstrated extraordinary resilience when it mattered most.
Eight of the 12 break points Djokovic earned went unconverted—a testament to Navone’s mental fortitude and intelligent shot selection. Even when the legendary champion generated chances to seize momentum, the youngster refused to break. His willingness to chase every ball, his court sense, and his refusal to surrender defined his performance.
The victory offers Navone a gateway to relevance on tennis’s grandest stages. A young player who suddenly proved he belongs among the sport’s elite, he seized an opportunity created by circumstance and exploited it with surgical precision.
Implications beyond one match
Djokovic’s first-round exit carries implications that ripple far beyond Arthur Ashe Stadium. For the first time since 2003, a Grand Slam tournament will not feature Djokovic, Rafael Nadal, or Roger Federer in the second round—a symbolic end to an era of dominance that defined professional tennis for two decades.
The consequences reshape the tournament landscape entirely. With Jannik Sinner absent and Carlos Alcaraz returning after merely four months away from a wrist injury, the bottom half of the draw has been fractured. Suddenly, American hopes of breaking a drought dating to Andy Roddick’s 2003 championship don’t seem entirely fanciful. Frances Tiafoe and Brandon Nakashima now find themselves in a portion of the draw with genuine opportunity, though Daniil Medvedev, the tournament’s defending champion, remains a formidable obstacle.
The question of tomorrow
For Djokovic, Sunday brought humiliation he did not anticipate. Yet questions linger about his future. Though he departed in the first round, he had reached the Australian Open final in January and advanced to Wimbledon’s semifinals despite minimal preparation. He has spoken of competing at the 2028 Los Angeles Olympics. At 39, he has demonstrated he can still compete with tennis’s elite.
But competing and winning are different propositions. His pursuit of a record-extending 25th Grand Slam title feels, after Sunday, a little further away than it did 24 hours prior.
