PGA instructor Mark Crossfield explains how early bottoming out and positive attack angles cause fat and thin iron shots. He demonstrates launch monitor data showing how mis-hits occur, then presents practical range drills including lie variations, obstacle positioning, and hovering the clubhead to move low-point control forward.
Fat and thin iron shots share the same root cause: bottoming out the swing too early behind the ball.
Practicing from uneven lie variations trains subtle posture adjustments and spatial awareness.
Placing an obstacle 4–6 inches behind the ball prevents early turf contact and pushes your low point forward.
Hovering the clubhead at address encourages a downward delivery into impact.
