There are several proven methods for eliminating 3 putts.
The first one I want to talk about is developing feel and distance control from much practice and trial and error. Most people who often three putt are usually lacking in this area and need to especially practice on the practice putting green before their round for about an hour.
The second way to quickly avoid three putts is to take every putt seriously, especially short ones. I can’t tell you how many times I’ve seen people miss short putts by taking them for granted and rushing the putt. Three foot putts are called knee knockers for a reason! You should always follow a system when you address a golf ball and be consistent, as the system I’ve devised for my students (which applied to any time you hit a golf ball) is 1) Pick your spot 2) See the shot 3) Pre shot routine. This is a great system and when executed properly helps you really dial in your game.
