Navone upsets Djokovic in 2026 US Open first-round stunner

Argentine tennis player Mariano Navone pulled off a stunning upset in the first round of the 2026 US Open, defeating the legendary Novak Djokovic in what is being called one of the biggest shocks of the tournament. Djokovic, a multiple Grand Slam champion, was unable to advance past the opening round as the younger Navone outplayed him on the hard courts of Flushing Meadows. The result marks a significant moment in Navone's career and raises fresh questions about Djokovic's form heading into the remainder of the season.
