Trying to get a golf ball to almost stop dead can seem like a difficult thing to achieve. If the greens are dry and hard the tendency is for the ball to bounce over the back of the green. The skill in this shot is to get the ball spinning backwards as it travels forwards and then lands and stops.
Club selection is important to play this type of shot. A lofted club like a pitching wedge or a sand iron if you are in a bunker will give that lift and also the backspin.
In the video you can see how to approach the ball with the club and also how to hold the club to play the shot most effectively. As with most strokes some practice will help improve this area of your game.
