Overview

• Carlos Alcaraz beat Jannik Sinner in the US Open final to return to the top of the ATP rankings, his first time at No. 1 since 2023.
• Coach Juan Carlos Ferrero said the team trained for 15 days on Sinner‑focused details and confirmed a service‑motion tweak introduced last December.
• Serving efficiency proved decisive in the final, with Alcaraz producing more aces, no double faults and a higher first‑serve rate than Sinner.
• Alcaraz said his best tennis has not yet been seen, framing the New York title as a step in an ongoing push to improve.
• Sinner acknowledged he was too predictable and pledged to adjust his serve and add variety, as analysts highlighted Alcaraz’s broader options, even as points‑per‑tournament figures still favor Sinner for 2025.
