Sinner showed sportsmanship by apologizing to his opponent at the net after the match.
Jannik Sinner began his Miami Open campaign with a straight-sets victory over Damir Džumhur, winning 6-3, 6-3 at Hard Rock Stadium. A heckler repeatedly interrupted the match, directing comments at Džumhur and affecting the game's flow. Sinner maintained composure throughout, securing the win without faltering. After the final point, he approached Džumhur at the net and apologized for the disturbance, demonstrating good sportsmanship amid the chaos. During a changeover in the second set, chair umpire Renaud Lichtenstein spoke to his supervisor about the situation. Lichtenstein reported, “Damir is upset with the guy with the green shirt, and Jannik is telling me he’s betting on the match.” He added, “I don’t know what we should do. Maybe we could talk to him to relax.” The supervisor replied, “We’ve got security on the way. So … I think he’s just an idiot.” Security was dispatched to handle the spectator. This incident follows other disruptions in Sinner's recent matches, such as a heckler during his Indian Wells clash with João Fonseca, where Sinner calmly addressed the issue. Sinner now advances to the third round to face No. 30 seed Corentin Moutet, their second ATP Tour meeting after Sinner's prior win at Roland Garros 2024.
