Quarter-turn the trail hand to square the face at impact
Saguto Golf coach describes the trail (right) hand pointing at the target, then gradually making a quarter turn as it comes into the golf ball to get the club face square so the ball propels to the target. He warns that if you do not make this quarter turn you can keep the face open so long that you slice it, or hit a glancing blow that sends the ball to the right.
