Think about how you usually go about putting. You look at the green between the ball and the cup and “read” how much you think the putt will break on its way to the hole. You then make a few practice strokes and putt.
It’s the same series of steps I followed for the putt in the photo at above right—a 25-foot downhiller on the seventh green at Shinnecock Hills. I read four feet of break from right to left. As such I aimed four feet right of the hole. After making a few practice strokes to dial in the correct speed I putted.
Adding this grip-down motion to your arsenal isn’t a difficult change to make. As you can see in the photo above I’ve choked down about six inches and the only other changes I’ve made are to stand slightly closer to the ball and use a little more knee bend.
