Overview
- Novak Djokovic pulled out of Turin after winning the Athens ATP 250, citing an ongoing shoulder injury, and finalist Lorenzo Musetti was confirmed as his replacement.
- Carlos Alcaraz opened the Jimmy Connors group by defeating Alex de Minaur 7-6(5), 6-2 to begin his bid for a first ATP Finals crown and to strengthen his year‑end No. 1 push.
- Alexander Zverev beat Ben Shelton 6-3, 7-6(6) in the Björn Borg group to match Alcaraz with a winning start at the season-ending event.
- Organizers adjusted the order of play to grant Musetti an extra recovery day after Athens, with the Italian set to start against Taylor Fritz on Monday in Turin.
- Alcaraz can guarantee finishing year‑end No. 1 by reaching the final with at least one round‑robin win or by sweeping his group, while defending champion Jannik Sinner must win the title to have a chance.
