Consistency at contact in putting is critical. Guys on tour do not miss the center of the putter by more than two tenths of an inch. What I have here is that I have put a couple of barricades on the putter face to show the bracketed area that we are trying to find at impact. When we are looking at hitting the ball it needs to fit right in between that barricade. If I am off to the side I am going to hit one of these barricades and the ball will go sideways and we are not going to get a consistent repeatable contact. This is also important for the distance you hit the putt. If you hit it off the center not as much energy is being transferred to the ball and the putt is going to be short. You are always fighting with hitting the ball the right distance. So consistency at contact is critical. Here I have just a couple of barricades, you could use match sticks as an example. Anything that is going to give you that feedback and draw your attention and make you focus on hitting it in a very narrow spot. Let's take a look at it with a shot. What you saw was a good one and a bad one and how the ball came off the putter face. This gives you immediate feedback and is a great way to improve your putting. You can do it at home or on the golf course. Give it a try.
