What is a duff in golf?

Definition

A poorly executed golf shot, typically involving hitting the ground before the ball or making inadequate contact that results in a weak, short shot that fails to achieve intended distance or trajectory. Duffed shots often occur under pressure or from difficult lies and can significantly affect scoring and momentum. Understanding duff causes helps golfers identify and correct swing faults that lead to poor contact. Common duff causes include deceleration, poor weight transfer, and improper ball position. Eliminating duff shots often provides immediate improvement in consistency and confidence.
