Hinge and hold is how I describe the method for hitting short greenside pitches from the rough with a lob or a sand wedge. Here's a four-step guide to playing the shot the way Craig Perks does.
1. Rotate the club clockwise so the club face is slightly open. Now take your normal grip.
2. Address the ball by standing with your feet close together and a bit open, with the ball centered in your stance. Your weight should be slightly toward the target and your hands slightly ahead of the ball (A).
3. On the backswing, feel as if you're abruptly picking up the club by hinging (a.k.a. cocking) your wrists (B). Take the club back until you've formed a 90-degree angle with your left arm and the shaft. This will produce a steep angle of attack. (A shallow swing is no good because too much grass gets between the club face and the ball, resulting in poor contact.)
4. The downswing and the follow-through should be a continuous brushing motion. Keep the heel of the clubhead ahead of the toe by maintaining the left arm's 90-degree angle with the shaft through impact. At the finish your hands should be well ahead of your body, and the club's grip should be higher than the clubhead (C).
