Overview
- Jannik Sinner beat Carlos Alcaraz 7-6(4), 7-5 in Turin to defend the ATP Finals, becoming the first player to win the event without dropping a set in two different years.
- Alcaraz received treatment for right thigh/hamstring discomfort during the final and traveled to Bologna for an MRI that will guide Spain’s Davis Cup plans.
- Despite the loss, Alcaraz finishes 2025 as year-end No. 1 after an eight‑title, 70‑plus win season and significant gains on indoor courts.
- Sinner closes a year in which he reached all four major finals, won the Australian Open and Wimbledon, refined his serve to save key points in Turin, and will skip the Davis Cup to start offseason work.
- The rivalry ruled 2025 as the pair split the Grand Slams and won every event they both entered, with both camps targeting further technical gains ahead of 2026.
