What is Sidespin in Golf?

Lateral rotation of a golf ball that causes it to curve left or right during flight.

Full Definition

Sidespin is created by the face-to-path differential at impact — when the clubface angle differs from the swing path, the ball tilts its spin axis. A clockwise spin axis (for right-handed golfers) produces a slice (right curve); counter-clockwise produces a hook (left curve). The amount of curvature depends on spin axis tilt and ball speed. Modern ball flight research shows sidespin and backspin combine into a single spin axis — there's no pure sidespin without backspin. Eliminating unwanted sidespin requires controlling the face-to-path relationship, which is what GOATY's ENGINE and WHIP training addresses.
