This will flatten the plane on which your club approaches the ball. This will result in a lower, more boring trajectory, which will give you more roll. Your head and hands should be slightly behind the ball. This will promote a smooth, full-shoulder turn. Maintain light grip pressure.

By combining these elements, you will create a wider arc and turn fully behind the ball at the top of your backswing. You then will be poised to move back to the left side and swing powerfully to the ball with an upward, sweeping motion.
