Many golfers straighten their right arms when swinging their wedges which changes the arc width and leads to a lot of fat shots and inconsistencies. Here’s a simple drill to allow your torso rotation to control the rate of closure of the clubface and distance without independent hand motion.
Get the club up and bent outwards when you go to swing. From there, rotate your club through, keeping your right arm on the side of your shirt and your body’s rotation is squaring the club up and not independent hand motion. This drill will lead to great, crisp, contact with shallow delivery to hit distance wedges.
