Overview
- Carlos Alcaraz went 3-0 in round-robin play and received the ATP year-end No. 1 trophy on court in Turin.
- Félix Auger-Aliassime beat Alexander Zverev 6-4, 7-6 (4) to claim the last semifinal berth and set up his first ATP Finals semifinal against Alcaraz.
- Defending champion Jannik Sinner finished his group undefeated and without losing a set or a service game, earning a semifinal against Alex de Minaur.
- The schedule places Sinner’s semifinal in the afternoon and Alcaraz–Auger-Aliassime at about 20:30 local, leaving the late winner less recovery time before Sunday’s final; Alcaraz noted the shorter turnaround could influence readiness.
- Alcaraz leads Auger-Aliassime 4–3 in their series and has won the last four meetings, capping a season with Roland Garros and US Open titles among eight trophies.
