US Open Tennis Results 2026: The 2026 Flushing Meadows tournament delivered an unforgettable opening day as 24-time Grand Slam champion Novak Djokovic suffered his earliest major exit in over two decades. On a day marked by physical strain and fierce competition, world No. 49 Mariano Navone produced the match of his life to eliminate the Serbian star in five sets. Elsewhere in the draw, former champion Daniil Medvedev and American contender Jessica Pegula secured straightforward victories to advance to the second round.
Historic Upset: Novak Djokovic Stunned by Mariano Navone
In one of the most unexpected US Open tennis results in recent history, 39-year-old Novak Djokovic was knocked out in the first round by Argentina’s Mariano Navone. The 7-6(5), 5-7, 4-6, 6-2, 6-1 victory marked Navone’s biggest career win and ended Djokovic’s pursuit of a record-extending 25th Grand Slam crown.
The defeat marks Djokovic’s earliest Grand Slam exit since the 2006 Australian Open. Throughout the four-hour battle at Arthur Ashe Stadium, the four-time US Open champion visibly struggled with shoulder stiffness, back pain, and severe physical exhaustion.
“I pretty much despised every moment I spent on the court for that,” Djokovic stated in his post-match press conference. “It’s something that I’ve been carrying, unfortunately, pretty much every match this year. Vomiting, throwing up… Then my whole body starts to collapse, basically cramping and pain.”
Navone, who entered the match with respect for his childhood idol, capitalized on Djokovic’s declining service speed and restricted lateral movement in the final two sets. After dropping the second and third sets, Navone elevated his baseline intensity, breaking Djokovic four times in the fourth and fifth sets combined.

Daniil Medvedev Restores Momentum with Clean Victory
