The Mechanics Behind the Mastery

Grip and Stance

Sinner employs a strong semi-western grip, positioning his index knuckle on bevel 4. This grip facilitates significant topspin while allowing for flat shots when necessary. His stance varies between semi-open and neutral, enabling effective weight transfer and optimal hip rotation. (playtennis.sg)

Swing Path and Timing

His forehand features a long, graceful swing with a compact backswing, allowing him to handle fast-paced, low balls efficiently. The swing path is characterized by a low-to-high motion, generating both power and spin. Sinner's exceptional timing enables him to meet the ball early, robbing opponents of reaction time.
