Full Definition
Shaft lean describes the position where the hands and grip are ahead of the clubhead at impact, creating a forward-leaning shaft angle. This position is critical for compressing the ball, controlling trajectory, and generating consistent distance. Amateur golfers commonly have negative shaft lean (hands behind the ball) — scooping — which produces weak, high-spinning shots with no compression. Elite golfers maintain positive shaft lean (4-7 degrees forward for irons) by stabilizing the lead side and resisting the urge to help the ball up. GOATY's WHIP score tracks the shaft lean quality that distinguishes elite from amateur impact positions.
