sportsmanship

Jannik Sinner defeated Damir Džumhur 6-3, 6-3 in the first round of the Miami Open at Hard Rock Stadium, despite disruptions from a heckler targeting Džumhur. The chair umpire addressed the issue during a second-set changeover, noting Džumhur's upset with a spectator in a green shirt. Sinner showed sportsmanship by apologizing to his opponent at the net after the match.
