#NavoneUpset is the hashtag for the August 30, 2026 US Open first-round shocker in which 25-year-old Argentine Mariano Navone beat No. 4 seed Novak Djokovic 7-6 (5), 5-7, 4-6, 6-2, 6-1 in a four-hour-36-minute night-session marathon at Arthur Ashe Stadium. It was Djokovic’s first Grand Slam first-round loss in 20 years — ending a 78-match first-round win streak at the majors — and his first pre-third-round exit ever at the US Open. Playing while visibly ill (he vomited courtside several times, per ESPN), Djokovic ground through three sets before Navone pulled away.

What Happened
Djokovic came into the 2026 US Open as the No. 4 seed and a four-time champion, with a 78-match first-round win streak at the Grand Slams stretching back two decades. Navone, a 25-year-old from Argentina who had won his first ATP singles title earlier in 2026, drew Djokovic in the opening round. Djokovic looked visibly ill from the first set: ESPN reported he vomited courtside on multiple changeovers and appeared to be in physical pain through the fourth and fifth sets. He ground through the first three sets, taking the second and third to lead two-sets-to-one, but faded badly as the match crossed the four-hour mark. Navone closed out 6-2, 6-1.
Reactions
Historic-upset framing. ATP Tour, CNN and CBS Sports all led with the 20-year historical marker; ESPN framed the loss as Djokovic’s body finally giving out under Grand Slam conditions. Sky Sports called it the longest first-round Grand Slam match of Djokovic’s career.
The night-session moment. Because the match unfolded under the Arthur Ashe lights and stretched past 1 a.m. local time, clips of Djokovic vomiting on the sideline, Navone’s stunned reaction to championship point, and the moment of the handshake circulated widely on X, TikTok and Instagram overnight — and formed the visual core of the hashtag through the next 48 hours.
Career-biggest for Navone. The ATP Tour’s own recap called it “by far the biggest win in the 25-year-old Argentinian’s career.” Navone himself flagged the surreal quality of the moment in his on-court interview.
Aftermath
Navone advanced to the second round, where the American tennis and Argentine media coverage of his run continued through the first week. Djokovic’s post-match press conference focused on the illness and physical breakdown rather than Navone’s play, and speculation about his 2026 fall schedule and long-term Grand Slam future dominated tennis commentary through the first week of September. The #NavoneUpset tag now sits alongside a small handful of other career-defining Grand Slam upsets as one of the sport’s viral shock-result moments of 2026.
