Novak Djokovic Stunned by Mariano Navone in US Open First Round

Novak Djokovic's bid for a record-extending 25th Grand Slam title came to a shocking end at the 2026 US Open after the Serbian legend suffered a five-set defeat to Argentina's Mariano Navone in the opening round.

Playing under the lights at Arthur Ashe Stadium, fourth-seeded Djokovic was beaten by the world No. 49 7-6(5), 5-7, 4-6, 6-2, 6-1 in a gruelling contest that lasted 4 hours and 36 minutes.

A Historic Early Exit

The defeat was extraordinary given Djokovic's remarkable Grand Slam consistency. It was his first first-round defeat at a major since the 2006 Australian Open, more than two decades ago. He had also never previously lost in the opening round of the US Open.

The result ended Djokovic's latest attempt to win a record 25th men's singles Grand Slam title and added one of the most unexpected chapters to his legendary US Open career.

Djokovic Battled Severe Physical Problems

The match was heavily influenced by Djokovic's physical condition. The 39-year-old appeared to struggle from the early stages and repeatedly showed signs of discomfort.

He vomited several times during the match and later battled cramping, back pain and shoulder problems. He also required medical attention before the final set. Despite those difficulties, Djokovic continued fighting and managed to take a two-sets-to-one lead.

However, his physical condition deteriorated significantly in the fourth and fifth sets. Navone took advantage, winning the final two sets 6-2, 6-1.

Navone Produces a Career-Defining Victory

For Mariano Navone, this was a landmark moment.

The 25-year-old Argentine showed impressive composure against one of the greatest players in tennis history. Rather than being overwhelmed by the occasion, Navone maintained his intensity, extended rallies and consistently tested Djokovic's movement.

His victory is comfortably the biggest of his career and sends him into the second round of the US Open with enormous momentum.

How the Match Turned

Djokovic started strongly enough to remain competitive despite his physical struggles. Navone won the opening-set tiebreak, but Djokovic responded by taking the second and third sets.

That comeback appeared to put the four-time US Open champion in control.

Instead, the match dramatically shifted in the fourth set. Djokovic's movement became increasingly restricted, his serve lost effectiveness and Navone began to dominate the longer exchanges.

Navone won the fourth set 6-2 before racing through the deciding set 6-1.

According to match statistics, Djokovic also committed 70 unforced errors, including 29 in the final two sets, underlining how difficult the latter stages became for the Serbian.

A Defeat That Raises Bigger Questions

The loss inevitably raises questions about Djokovic's future at the Grand Slam level.

At 39, Djokovic remains one of the most accomplished athletes in sporting history, but the physical problems he experienced against Navone have added to concerns surrounding his ability to sustain the demands of five-set tennis.

His recent season has included another early defeat in Cincinnati, while he reached the Wimbledon semifinals and finished runner-up at the Australian Open.

It would be premature to draw conclusions about the end of his career from one defeat. However, the US Open loss represents a significant moment in the later stages of Djokovic's extraordinary career.

Djokovic's Legacy Remains Untouched

Despite the shock defeat, Djokovic's achievements remain unparalleled.

The Serbian has won 24 Grand Slam singles titles, including four US Open championships, and has spent years redefining longevity and consistency in men's tennis.

His loss to Navone does not diminish that legacy. Instead, it highlights the unpredictable nature of elite sport—and provides Navone with an opportunity to create a major story of his own.
