This story is for you if...
• You miss putts left or right even when they feel good
• Your putting distance control is erratic
• You're not sure your putting stroke is solid
You spend hours on the practice green but you still aren't getting the results you want.
WHY IT'S HAPPENING
If you're inconsistent, you may be using too much wrist action in your stroke. This causes you to flip the putter up through impact so that you catch the ball on the bottom half of the face.
HOW TO KEEP YOUR STROKE LEVEL
Place a Band-Aid on the bottom third of the putterface as shown above and stroke a few practice putts. Your goal is to strike the ball above the Band-Aid. You'll know when you make contact with the Band-Aid because the putt will feel dead and it will come up short. Practicing like this forces you to keep the putter level through impact and, at the very least, to make sure that you don't flip the club up into the ball.
BONUS: FIX YOUR DIRECTION, TOO
If you strike the ball with the toe of the putter higher than the heel, the ball will go left of your target. When the heel is above the toe, the ball will roll right of your target. Since this drill ingrains a level path, you gain the added bonus of controlling both speed and direction.
