Overlap: Zach JohnsonWhat It Does: Positions the hands closer to one another so they can better
act as a single unit. Since neither hand dominates, it allows guys like Zach to use a stronger grip (hands rotated more to the right) without fear of hooking the ball.
How to Do It: Set the pinkie on your right hand in the crease between the index and middle fingers of your left hand.
You know you need it if: You tend to lose control at the top (i.e., point the clubhead in different directions).
