Carlos Alcaraz ended world number one Jannik Sinner's 26-match winning streak with a 7-6 6-1 win in the Italian Open final.
Sinner, playing in his first tournament since a three-month doping ban, was hoping to become the first Italian men's singles winner at the tournament since Adriano Panatta in 1976.
But after edging a tense tie-break, four-time Grand Slam champion Alcaraz was a class above in the second set, needing just 33 minutes to wrap up the title.
Sinner had two set points in the first set but hit a backhand return wide to let defending French Open champion Alcaraz off the hook.
