Novak Djokovic's Upset at U.S. Open: Popyrin Triumphs

Novak Djokovic experienced a surprising defeat by Alexei Popyrin at the U.S. Open. The Serbian, chasing his 25th Grand Slam title, was outplayed by the Australian in four sets. Djokovic cited exhaustion from recent competitions. Popyrin celebrated his victory, advancing to the tournament’s fourth round.

In a significant upset at the U.S. Open, Novak Djokovic's quest for a 25th Grand Slam title was halted by Alexei Popyrin with scores of 6-4, 6-4, 2-6, 6-4. The Serbian star, exhausted from his recent triumph at the Olympics, could not match the Australian's energy.

Djokovic reflected on his performance: 'I spent a lot of energy winning the gold, and I arrived in New York mentally and physically drained. I gave my best, but I just felt out of gas.' Popyrin, who had previously lost to Djokovic at the Australian Open and Wimbledon, seized his moment.

'Third time lucky, I guess,' Popyrin said. The upset occurred a day after third seed Carlos Alcaraz was also defeated, adding drama to the tournament's early rounds. Popyrin now faces American Frances Tiafoe in the next round.
