Novak Djokovic, the reigning champion, suffered a stunning third-round exit at the 2024 US Open, losing to Australian Alexei Popyrin in a four-set battle. The Serbian star admitted that it was one of the worst performances of his career, citing fatigue from his Olympic campaign in Paris. Djokovic, who had a high number of double faults, struggled throughout the match, especially on serve. Popyrin capitalized on Djokovic’s vulnerabilities, securing the first two sets before Djokovic fought back to win the third. However, Popyrin ultimately prevailed in the fourth set, ending Djokovic’s hopes of becoming the first player to win 25 Grand Slam titles.
