The biggest issue facing golfers in their short game is improper swing technique. The tendency of most golfers is to take a substantial backswing and to follow that by using a soft stroke.
Then, just prior to contact, the average golfer tends to begin decelerating the club. The tendency is to ease up just prior to contact so as to be sure to not strike the ball too hard. Adding to the problem, most players tend to bring the club nearly to a stop instead of following through.
To stop flubbing those chip shots, you must do the complete opposite. Instead, you need to keep the backswing short, then apply a firm downward blow. Most important, you must complete the shot with a follow-through that matches or exceeds the length of your backswing.
Here are some techniques you can use with your wedges as well as as a 7-, 8- or 9-iron.
Place your feet close together and open your stance so that your body is facing your target.
Place your weight on your front foot and leave it there.
Advance your hands in front of the ball.
Focus entirely on the ball, concentrating on keeping your head still, eyes on the ball.
Take the club back a short distance, slowly and smoothly.
Swing downward through the ball---do not decelerate the club!
Take your divot and follow through.
Keep your head down and your eyes on the contact spot until you have finished your follow-through.
Tips & Warnings
Never try to lift the ball. Instead, swing down and let the ball roll backward up the face of the club on contact. Keeping your swing as short as possible ensures that you will be able to swing firmly. Throughout the swing, keep your weight on the front side and be sure to keep your head still. Swinging firmly means you can shorten your backswing; just be sure to adjust accordingly.
