Overview
- Sinner defeated Felix Auger-Aliassime 7-5, 6-1 in Turin, taking control after the Canadian suffered a left-calf problem late in the first set and took a medical timeout.
- Auger-Aliassime’s movement visibly dipped after 6-5 in the opener, with broadcasters noting the issue before he sought treatment, and Sinner’s serve carried him through a routine second set.
- Next up for the defending champion is Alexander Zverev on Wednesday, after the German opened Group Borg by beating Ben Shelton 6-3, 7-6.
- Lorenzo Musetti, a late entrant following Novak Djokovic’s withdrawal, lost his debut 6-3, 6-4 to Taylor Fritz and said the quick turnaround from the Athens final left him with heavy legs.
- Musetti faces Alex de Minaur in his second round-robin match, as the tournament marks the first ATP Finals edition featuring two Italian singles players.
