With putting we are at the simplest form of the golf swing. We are basically concerned with two different issues, controlling direction and controlling distance. Direction is going to be controlled by the clubhead and the aim of the clubhead. The most critical part of all golf shots is that you need to learn to aim the clubhead. What I have here is a shaft lined up on my target line that helps me get the putter face perpendicular to my intended line. Then I want to get a nice direct swing away from the ball and back into the ball, kind of tapping the shaft forward. My control of direction is really away and into the ball, not really after impact by following through to the hole. Secondly, we want to get a sense of controlling the distance of the putt. We are going to do that by getting an even swing into the putter. The best distance drill is to put a coin on the green and place balls on the same line at different distances. Make a practice swing looking at the target, just trying to feel a nice relaxed pendulum, aim your putter on your intended line and then just make your swing for distance. The idea is to get your grouping to the quarter and just try to tighten your pattern, trying to stop the balls on the quarter. As I go back to the third ball what I am doing is just keeping the same rhythm in the stroke as the first two balls but allowing the stroke to get naturally longer to roll the ball just a lit bit further. Through practice you should be able to get a nice tight pattern like this. Putting is largely a function of percentages. Tighten the pattern to your target area and more putts are going to go in and you are going to three-putt less.
