TURIN, Italy — And so the year ends as it began, with Jannik Sinner’s arms around a big sliver trophy, making a mess of the competition and tennis history for his suddenly tennis-mad country.

Zverev faced world no. 3 Carlos Alcaraz in the final round-robin match and earned a 7-6, 6-4 triumph, beating the Spaniard for the second straight year in Turin. It was their 11th duel, and the German ousted the young Spaniard for the sixth time, bouncing back after two consecutive losses this year.

Jannik Sinner and Carlos Alcaraz have been placed in different groups for the ATP Finals in Turin. That means the earliest they could meet is the semifinals.
