Here is one out of about 100 putting drills that I learned from the great putting teacher, one of my great friends, Jackie Burke. Super creative person and I have seen a lot of people copy this one, but I heard it first from Jackie many years ago when we were playing down at the University of Houston. He would have you take your pitching wedge and putt with it. In order to putt well with a wedge, you can do this with a sand wedge or any club, you need to hit right on the equator of the ball. That is important for all of your putts. You want to hit in the center of the golf ball. Not underneath it which will cause the ball to have backspin on it and not on top of it which will cause it to drag and snap into the grain and bounce a little bit. Putting with the wedge does a number of things for you. It gets your focus on the back of the ball and it smoothes out your stroke after a short period of time as well. It is a great little drill and when you put a good roll on it you can make a lot of putts doing this. It might surprise you how well you do putt with the wedge. I have used this with all levels of players, it is not really an advanced, intermediate or beginner drill, anybody can do this. Keep your club off the ground at address, make a smooth back and through motion and you will get real good at hitting the equator of the ball which will translate into making more putts.
