Overview

• Jannik Sinner has resumed training at the Monte-Carlo Country Club, rehearsing his service motion without a racket after losing the US Open final to Carlos Alcaraz.
• Sinner said he will make small technical changes to his serve, signaling targeted tweaks rather than a wholesale overhaul.
• Over the past 52 weeks he ranks 54th in first‑serve percentage at 60.6%, yet he is third in first‑serve points won at 78.9% and leads the tour in second‑serve points won at 59.6%.
• In the US Open final Alcaraz created 11 break chances and Sinner lost 42% of points on his own serve in a 6-2, 3-6, 6-1, 6-4 defeat.
• His reported schedule lists Beijing and Vienna next, with participation in Paris‑Bercy uncertain and a potential Alcaraz rematch during the Asian swing discussed by observers.
