Learn consistency and ball control by always aiming at specific targets when you are on the practice range, but do not just aim at the target, use the entire target area, aim to the left, right, short and long and develop that control to hit more fairways and greens than you ever imagined
Start with a neutral grip making sure that your left hand is not turned over or under the shaft, this will prevent you from manipulation the clubface at the top of the backswing
Developing resistance on the through swing of your pitch shots is critical for control, this retraction drill will also keep your club accelerating, avoiding the biggest mistake in pitching which is a decelerating clubhead
