The claw putting grip has become popular recently because it takes the right side out of the putting stroke and gives you more of a fell of pushing the ball to the hole
Grip the club in your fingers, have your thumbs and index fingers pinched together to support the club at the top of your backswing and apply your grip pressure at a medium level
This simple drill helps you get your eyes in the correct putting position, teaches you how to putt down your target line correctly and to read greens
