Distance control in the short game is one of my favorite things to teach. For golfers that average a score over 85 you can shave the most strokes quickest by getting on the green with an up-and-down attempt from 0 to 50 yards and getting on the green from 50 to 100 yards.
For distance control you need a club head speed “governor.” For most golfers swing size or length is the better governor, and easier to conceptualize. Most golfers have 3 to 4 wedges (PW, Gap, SW & LW). I teach them swing sizes based on a clock or Dave Pelz’s fractional system, whichever they best respond to. Swing sizes of 7:00 to 5:00, 8:00 to 4:00, 9:00 to 3:00, and 10:00 to 2:00 multiplied by the 3 or 4 wedges will give a “table” of carry distances. For longer shots out to 100 yards, I teach using the 9:00 and 10:00 backswing length to full finish, times the number of wedges.
