POSITION THE BALL
First thing is aim. Aiming the putter is a function of a player’s vision, and we’re all different. Putterface aim is determined by the front-to-back ball position. Every player has a front-to-back position that correlates to perfect aim. If the ball gets in front of that spot, the putter is aimed left. If the ball moves behind it, the aim is to the right. (A 3-cm change shifts the aim by 10 centimetres for every 3 metres.) Place the ball where it feels correct, then have a friend check from behind if the face is aimed at the hole, or left or right. Adjust accordingly.
