Overview
- Jannik Sinner defeated Félix Auger-Aliassime 7-5, 6-1 in Turin to open his round-robin campaign.
- He converted his first match point with an ace after about 1 hour 40 minutes, stretching his indoor winning run to 27 matches.
- Auger-Aliassime injured his left calf late in the first set, took a medical timeout in the second, and struggled to maintain his level.
- His status for the scheduled meeting with Alexander Zverev is uncertain, while Sinner is due to face Ben Shelton next.
- In the session's other result, Taylor Fritz beat Lorenzo Musetti 6-3, 6-4, and Sinner's year-end No. 1 chances still hinge on Carlos Alcaraz's group results.
