Overview
- Novak Djokovic pulled out after the Athens final citing a shoulder injury, removing the seven-time champion from Turin hours after his 101st career title.
- Lorenzo Musetti was promoted into the Jimmy Connors Group, arrived on Sunday, and lost his debut 6-3, 6-4 to Taylor Fritz, saying he was not at 100 percent physically.
- Carlos Alcaraz defeated Alex de Minaur 7-6 (5), 6-2 to win his first opening ATP Finals match and said he preferred facing Musetti rather than Djokovic in the group.
- Defending champion Jannik Sinner began with a 7-5, 6-1 win over Felix Auger-Aliassime; Sinner needs the title to have a chance at year-end No. 1, while Alcaraz controls the race with strong results.
- Alexander Bublik is the first alternate and Casper Ruud accepted the second alternate spot, as organizers adjusted the order of play following Djokovic’s late withdrawal.
