Novak Djokovic loses to Thiago Agustin Tirante at Cincinnati Open

Novak Djokovic cruised through the opening set of his return to competitive tennis before experiencing a severe physical collapse in the stifling Ohio heat and humidity, falling 2-6, 6-4, 6-4 to Argentina's Thiago Agustin Tirante in the second round of the Cincinnati Open on Saturday, August 15, 2026. The 2-hour, 44-minute encounter ended a 10-match winning streak for Djokovic at the tournament and left the 24-time major champion casting severe doubt on whether he will ever return to the ATP Masters 1000 event, according to reporting by the New York Post and Yahoo Sports.

But the momentum shifted dramatically in a grueling second set that featured an 18-minute third game. During that pivotal sequence, Djokovic fought off four break points across nine deuces before securing the game, yet he was visibly in distress, bending over between points and dropping to his hands and knees on the court noted The Straits Times.

As the conditions intensified, Djokovic appeared to vomit into a towel during a changeover. He summoned a trainer and a doctor for ice towels and medical assessments, taking a medical timeout that prompted both players to retreat to the locker room to cool off reported the New York Post.

Revived enough to dictate the early pace of the deciding set, Djokovic maintained parity until the ninth game. There, he saved three break points before misjudging a drop shot to gift Tirante a fourth opportunity, which the 25-year-old Argentine converted according to Arkansas Online. Tirante then held serve to seal the biggest victory of his career, capitalizing on another missed Djokovic drop shot on match point noted Sky Sports.

"This is the best win of my career. I really did a good job inside the court. I managed very well the nerves of playing against a legend like Novak. Now I feel relieved."

Speaking to international reporters after the match, Djokovic went further than detailing the immediate weather conditions, disclosing that his on-court collapse was heavily tied to an undisclosed medical ailment reported the New York Post. The three-time Cincinnati champion explained that the environmental factors compounded a chronic physical issue noted Yahoo Sports.

"It's just a condition that I have, health wise, that has been bothering me for the past couple of years. [It causes] a lot of issues, especially when it is humid and it is hot. I did anticipate it, but there are all these things, like nerves and everything involved that makes it worse, and that's what happened."

Asked about his long-term future at the Ohio tournament, Djokovic offered a blunt assessment of his prospects reported the New York Post. It looks like I won’t be back, unfortunately, to play here, he admitted according to The Straits Times, adding that he must now look ahead noted Arkansas Online.

Djokovic turns his immediate focus toward the U.S. Open, which begins on August 30, where he will attempt to recover his physical equilibrium and resume his pursuit of a record-extending 25th Grand Slam title reported Yahoo Sports.
