Jannik Sinner defeated Jiri Lehecka 6-4, 6-4 in the Miami Open final to claim the Sunshine Double, becoming the first man since Roger Federer in 2017 to win both Indian Wells and Miami back-to-back. He achieved the feat without dropping a set, a first in the tournament's history. Rain delays disrupted the match, but Sinner maintained control throughout.
Sinner, the world No. 2, entered the final after a dominant run, including a 6-3, 7-6(4) semifinal victory over Alexander Zverev. He fired 10 aces in the final at Hard Rock Stadium, contributing to his tournament total of 70 aces. The Italian broke Lehecka early in the first set and converted a key break at 4-4 in the second after another rain interruption, securing the title in 1 hour and 33 minutes. Lehecka, who had not been broken all tournament prior, saved some break points but could not overcome Sinner's baseline dominance and flawless first-serve points in the opener (16/16 won).
