The club should travel back along the body line ( outside ) Set the wrists in the backswing so that the club face remains open and will stay open through impact. Club head should enter the sand at the point you were staring (2 inches behind the ball) and accelerate through impact on the body line (inside path) maintain the slightly open club face. Body Rotates to a full finish!
Set up with the club face closed, using the full swing grip… this creates a digging leading edge. To get the ball out of the buried lie. Align the body square to the target with the weight slightly on the front foot… this is to promote a descending blow. The ball should be slightly forward of center. Levitate the club head over the point in which you are focused on the club entering the sand.
A good lie is important to pull off this shot. Very similar to the green side bunker shot. (Setup) Long and lazy stroke. Grip down on the club. Shaft angled slightly away from the target. Ball position forward. Weight evenly distributed.
