Djokovic Struggles Physically

Djokovic's physical condition became a major factor as the match progressed. The Serbian struggled with energy and appeared to deal with cramping and pain during the later stages.

Djokovic also experienced vomiting during the match and received medical attention. He later indicated that back and shoulder problems had affected him as the contest went on.

Why the upset matters:

Djokovic's defeat marks his first opening-round loss at a Grand Slam since the 2006 Australian Open. It was also the first time he had been eliminated in the opening round of the US Open.

A Historic Early Exit for Djokovic

Djokovic arrived in New York chasing a record 25th Grand Slam singles title and another US Open championship. Instead, his tournament ended after just one match.

The defeat is particularly notable because Djokovic had never previously lost his opening match at the US Open during his career. His run at Flushing Meadows had previously extended far beyond the first round across his many appearances.

Navone Completes One of the Biggest Wins of His Career

For Navone, the victory represents a breakthrough moment on one of tennis's biggest stages. The Argentine remained composed despite playing one of the most decorated players in tennis history.

After dropping the third set, Navone responded emphatically. He won the fourth set 6-2 before racing through the deciding set 6-1 to complete the upset.

Djokovic's US Open Campaign Ends

Djokovic's elimination means the 2026 US Open men's singles draw has lost one of its biggest names before the second round.

The result also ends Djokovic's immediate pursuit of another US Open title and the record 25th Grand Slam crown he was targeting in New York.

What Happens Next for Mariano Navone?

Navone now advances to the second round of the US Open, carrying the confidence of a victory over one of the greatest players in tennis history.

His challenge will now be to recover quickly and maintain the level that produced the biggest upset of the opening day.
