Novak Djokovic suffers a shocking defeat at the Cincinnati Open as Thiago Agustín Tirante capitalizes on the Serbian's heat-related struggles. The tennis legend, known for his dominance, fell 2-6, 6-4, 6-4 in a match that exposed his vulnerability in extreme humidity.
Djokovic's Early Lead Fades in Cincinnati Humidity
The match began promisingly for Djokovic, who cruised through the opening set 6-2. However, the notorious Ohioan humidity soon took its toll. By the second set, Djokovic was visibly struggling, squatting between points and calling for the physio and doctor while leading 6-2, 2-1. He vomited into a towel and had his blood pressure checked, but continued at half-speed for the remainder of the match.

Tirante, ranked world No. 50, remained composed and used his powerful serve and forehand to keep Djokovic on the defensive. The 25-year-old Argentinian sealed the biggest win of his career, breaking Djokovic's serve at crucial moments to close out the match in three sets.
Djokovic's Non-Slam Struggles Continue
This loss marks Djokovic's third consecutive non-grand slam tournament without reaching the quarter-finals this season. He now holds a 2-3 record at Indian Wells, Rome, and Cincinnati. The 39-year-old has openly prioritized grand slams and the Olympics, but this early exit raises questions about his fitness and scheduling.
Despite reaching the final at Roland Garros and the semi-final at Wimbledon, Djokovic's form outside the majors is a growing concern. His post-match comment, "It was not an enjoyable match for me, for sure, the way I felt," underscores the physical toll the heat took on him.
