Putting Stroke and Face Rotation
Have you ever heard the advice "straight back and straight through?"
I've seen and heard this advice many times. I think it's a good image to have. It should help you keep your face square through impact.
But technically, it can't be done because of the way humans are built.
Natural Putting
When putting, you can go with straight back and through or rotational putting stroke.
There is no correct answer to this. You should choose what works for you.
With rotational putting stroke, putter face opens on the backstroke, squares at impact and closes on the follow through.
But some rotational putters have different stroke than the basic one like above.
Tiger Woods once said that his stroke path is 1 degree in to out through impact when he is most consistent.
So the correct stroke path differs depending on the golfer.
To practice the putting stroke, Tiger Woods often putts with his right hand only.
I remember seeing him putt with his right hand in practice. It almost makes me think that he can make more putts with his right hand only.
