The world No. 49 battled past the four-time US Open champion 7-6(5), 5-7, 4-6, 6-2, 6-1 in a marathon that lasted four hours and 36 minutes.

Navone made a remarkable comeback after Djokovic took control of the third set. The Argentine then dominated the final two sets, winning 6-2 and 6-1 to complete one of the biggest victories of his career.

The defeat marks Djokovic’s first-ever first-round loss at the US Open. It also brings an end to his extraordinary streak of 77 consecutive opening-round victories at Grand Slam tournaments, a run that stretched back to the 2006 Australian Open.

The match was also the longest first-round Grand Slam match of Djokovic’s career, adding another remarkable chapter to the Serbian legend’s storied career.

For Navone, the victory represents a career-defining moment on one of tennis’ biggest stages, while Djokovic’s shock exit leaves the 2026 US Open without one of its most decorated contenders from the very beginning.
