Get to grips with this important shot to see improvements in your scores.
Seldom is there a need to fly the ball all the way to hole. The run of the ball is much more predictable when it's on the green rather than in the air - lobbing the ball up high brings into play wind direction and backspin, which is difficult to predict. A bump and run gets the ball rolling quicker, making it a much more predictable shot with a higher success rate.
Using your pitching wedge (because it will impart less spin to get the ball rolling), play the ball middle to slightly back in the stance, gripdown the club a touch for more control, and push your hands and weight slightly forwards towards the target.
Next, get a clear focus of where you want the ball to land in order to roll out towards the hole. Swing the club back to halfway, and accelerate into the back of the ball, finishing with your arms and club pointing towards the hole.
Think of this as an arms and body swing; turn your body and swing your arms through together. Resist the urge to help the shot with your hands at impact.
Use minimal wrist hinge during the backswing. Unhinging adds swing speed making it more difficult to judge distance control.
To improve your technique, use a bag towel under your arms whilst you are practising this shot. This will help to keep the body and club moving together, which, in turn, will give you the feeling of staying more connected throughout.
