If you have trouble gauging the distance of your pitch shots, let me suggest something that has help me a lot.
Get your wedge out, like a 54 or 56. Address the ball with narrow stance, little narrower than your shoulders.
From this stance pitch the ball with a smooth solid stroke.
Measure how far the ball went...walk it off, a range finder would be better.
By doing this I now know I can hit a good solid pitch about 55-60 yards. On the course I use this as my point of reference when I need to stick a pitch close.
Just a suggestion.
Hope it helps you as much as it has helped me.
