Most often , making fine pitch shots is a matter of being aware of the ball’s lie situation and hitting it accordingly. You won’t have to change much of anything in your stance or stroke, just attempt to make good contact with the ball.
Check the lie carefully before your pitch shot . Then, try some practice swings in similar conditions, somewhere away from the ball. There are 3 situations in which your ball will likely lie. The first is the ball is sitting in an up position on top of the grass. The second is when the ball is sitting in a low rough. And 3rd is when the ball is lying in a deep rough. Let’s describe what to do in each situation.
Ball is sitting up -This is where the ball is sitting on top of the grass. Keep your stance the same , and play the ball mid way between your feet. Here your swing will bottom out under your ball.
Ball is sitting is sitting in low rough - In this case, you will position the ball off your back foot. You want your shaft to lean toward your target, so you want to set your hands in front of the club head. You want to get a good solid hit on the ball, not the turf .
Ball is in a deep rough - Place the ball nearer your front foot. Now, keep your hands forward of the club head, and swing at a spot beneath the ball. If the grass is extremely thick, you will want to open the club face in your hands because the thick grass will try to close it . Not opening the face before swinging will result in a shot that is pulled low and left .
It’s best to have 3 wedges for these types of shots , pitching, auxiliary and lob. Golf clubs of this type can be purchased from pro shops and online retailers who offer discount golf clubs and clone golf clubs.
