Novak Djokovic loses in opening round of US Open for first time, falling in 5 sets to Mariano Navone

Key Points:

• Novak Djokovic, the 39-year-old 24-time Grand Slam champion, was defeated in the first round of the US Open by Mariano Navone in a five-set match lasting 4 hours and 36 minutes, marking his earliest Grand Slam exit since 2006.
• Djokovic struggled physically throughout the match, suffering from vomiting, cramping, and back and shoulder pain, which severely affected his performance and led to 70 unforced errors.
• This loss, coinciding with the 21st anniversary of Djokovic's US Open debut, raises questions about his future in Grand Slam tournaments as he admitted uncertainty about how much longer he can continue competing at this level.
• Navone, a 25-year-old Argentine who won his first ATP singles title earlier this year, celebrated his first five-set victory against Djokovic, calling the experience a dream come true against one of tennis's greatest players.
• Djokovic's recent form has been challenging, including a first-round loss at the Cincinnati tournament earlier in the month, and he expressed concerns about the difficulty of opening matches in recent years despite hopes for better preparation.
