Sinner becomes the sixth player in history to defend his first title at ATP Finals

Jannik Sinner was crowned as the Master last year for the first time in his career and has managed to retain that status in these 2025 ATP Finals. It's not at all simple to win the first two titles in this event consecutively, as only five other men have achieved it in history: Nastase, Borg, Lendl, Hewitt, and Federer.

👑 They successfully defended their first title in the #ATPFinals:
