Overview

• Training footage on the China Open Centre Court shows coach Simone Vagnozzi restricting Sinner’s arm to encourage a shorter takeback on the service motion.
• Sinner committed to tweaking his serve after losing the US Open final to Carlos Alcaraz, identifying the shot as a priority for improvement.
• The world No. 2 enters Beijing as the top seed and 2023 champion, with Alcaraz competing in Tokyo rather than defending the title in China.
• Last season’s data highlighted room for growth on first-serve reliability, and the US Open final featured just 48% first serves made.
• Sinner has added physiotherapist Alejandro Resnicoff to his team on a permanent basis, as viral clips from Beijing practice sessions — including a pocketed ball catch — draw attention.
