Putting S.O.S. Fundamentals
Solid - hit the putt solid
Online - start the putt on the target line
Speed - hit the putt the correct speed
The Sweet Spot is also Vertical
It is important to hit the ball in the sweet spot of the putter, between the toe and the heel AND between the sole and top of the putter.
Keeping the putter too low will cause you to hit the ball too high on the face. It will usually launch the ball up, and won't roll until after it stops bouncing (it take a few inches, but that is enough to mess up the putt).
Bringing the putter up will hit the ball with the lower edge of the putter - bad contact. It is like hitting a full shot thin - it skids and is impossible to predict where it will stop :)
Try this: hit some putts purposely hitting the ball high and low on the face until you can feel what it is to hit it in the vertical sweet spot.
A couple of quarters behind the ball will help you raise the putter to the proper height at impact.
