Putting is very simple in nature. So is this drill. All you need are three quarters and a wide-open green. Spend 30 minutes on this tip and you'll be sinking birdies in no time.
Although the best putters gain the most strokes on short putts, when it comes to avoiding three-putts, distance control is priority no. 1.
Make your stroke even on both sides of the ball for Tour-level distance control.
If you want to kiss three-putting goodbye, set the face square at address and make sure it returns to square at impact.
