The top 2 factors in a great putt are rolling speed and direction. And to manage them in every hit, players have to pay much attention to set up: ball position, eye line position, balance stance, grip, hands and arms.
As listed below are 2 simple drills suggested by Tom Patri, founder of TP Golf Schools in Florida and a PGA Quarter Century Member.
Set up posture before getting started:
Shift the body weight to both legs, as well as to heels and toes. The eye lines are located on the ball directly or a part of the extended target line. A grip with comfortable hands and arms, to let the club head rotate naturally at impact without manipulation.
Drill 1 – Safe square:
Put 4 tees on the ground to form a “safe square” which is 1m2 in width and take 10 steps away from it (around 10m). Imagine the golf hole is the center of “safe square”, and now get 18 balls in a row inside it. If any ball stops outside, restart it from zero. This drill will help get used to the right stance, ball feeling and force using to shift the ball to the right place.
Drill 2 – Two gates:
Put 2 tees on the ground with the width of the putter’ head in between, and lay a ball in the middle of them. Firstly, putt the ball with this “gate” to get familiar to keeping the impact centered. Next, make the second “gate” which is a bit wider and 70 – 80cm away from the first one. Players have to putt 9 balls in a row through these gates, and restart from zero if any ball goes out. This drill makes standard putts with centered impacts, as well as accurate straight ball lines.
Be patient and keep practising these 2 drills at least for 1 month, you will find how your putting skills improved.
