Here is how to handle a ball below your stance. Sole the club to establish both your swing plane and posture. Stand closer to the golf ball. Move the ball a bit more forward in your stance from where it would normally be in a level lie. Widen your stance, pigeon toe your feet and flex your knees into the hill. Finally, make a three-quarter swing concentrating on keeping your balance throughout the swing. The ball will tend to fly right off the target.
