Following an exchange of initial service breaks, neither competitor truly asserted control over the contest, with both frequently struggling to maintain their serves.
Nonetheless, during the tie-breaker, Sinner elevated the consistency of his first serves, and after failing to convert the first of his two opportunities to close the set, a double fault from Alcaraz granted him the upper hand in the encounter.
Sinner had a slow start to the second set and was forced to recover from a 15-40 deficit in his initial service game before Alcaraz secured a break to establish a 2-1 lead, subsequently holding serve to make it 3-1.
However, the Italian managed to remain competitive since Alcaraz struggled to assert control in his service games. Sinner then took a 4-3 advantage, thereby increasing the pressure on his 22-year-old rival, who possessed a record of 10 victories in their 16 prior meetings.
A further unstable service game from the Spaniard provided Sinner with an additional break opportunity, and from that juncture, he capitalized decisively, swiftly securing his 27th ATP Tour triumph.
