Thiago Agustín Tirante of Argentina defeated Novak Djokovic 2-6, 6-4, 6-4 in the opening round of the Cincinnati Open. The Serbian player, who won the first set, struggled visibly from the second set onward as he battled the oppressive humidity and heat typical of Ohio conditions.
Djokovic spent stretches between points bent over and squatting as he fought to recover his breath. Tirante capitalized on the circumstances to secure the biggest victory of his career by claiming the final two sets.
