I am not a very good golfer.I recently read a old book by Ben Hogan.He say's not to use any muscle on a pitch shot.Or any other shot for that matter.The club should do the work.I use a variation of his technicqe.I use a sand wedge for anything 50 yards in.When you are up close to the green.Use a narrow stance.Use the Ben Hogan grip.Put the ball in the middle of your stance.Use a putting stance.Keep your arms straight.No twisting of the wrists.Bring the club back as if putting,only a little farther.Hit straight thru to the target.If your not taking a little divot then you are hitting too high up on the ball.You should use a half back swing and a complete thru swing.I am getting alot of air and back spin from this method.It takes alot of work but it is working for me.Just trying to help.Good luck
