Novak Djokovic was eliminated from the US Open in the third round by Alexei Popyrin, losing 6-4, 6-4, 2-6, 6-4. This marks Djokovic's earliest US Open exit in 18 years and the first time since 2017 that he will end the year without a Grand Slam title. Djokovic struggled with his serve, committing 14 double faults in the match. Popyrin, who had never previously defeated Djokovic, credited his recent performances and mental improvements for the victory. This upset came one day after Carlos Alcaraz was also eliminated, ensuring a new champion will be crowned. Popyrin's victory was witnessed by fellow Australian Lleyton Hewitt, the last player to beat Djokovic at this stage of the tournament.
