Holding the five biggest titles in men's tennis, Alcaraz and Sinner end 2025 with emphatic proof that their duopoly is only just beginning.

Jannik Sinner beat Carlos Alcaraz 7-6 (7-4), 7-5 to win the ATP Finals trophy for a second-straight year.

A nervous Sinner eventually closed things out with a late second break of Alcaraz, just avoiding a second tiebreak as the latter produced a number of unforced errors.
