Mariano Navone Stuns Djokovic in First Round of US Open, Ending 20-Year Streak

The Upset

Mariano Navone, a 25-year-old Argentine ranked outside the top 50, defeated Novak Djokovic in the first round of the US Open Monday in a five-set match that lasted four hours and 36 minutes. The final score was 2-6, 6-7, 7-6, 7-6, 6-4. It marked the first time since 2006 that Djokovic had lost in the opening round of a Grand Slam tournament. The 39-year-old 24-time Grand Slam champion visibly struggled throughout the match — vomiting during changeovers, stumbling, and breaking down in tears at the conclusion.
