What do you do when the ball is below your feet?  You should be aware of what goes into the shot.  First of all, the ball is farther away from you than with a normal stance, so you must widen your stance and flex your knees to get to the ball.  Gravity wants to pull you toward the ball when you swing, so you must remain still and stable during the shot.  Your club head will not square up to your line, so you should aim well left of your target. Make these slight adjustments when the ball is below your feet and you will improve your scores.
