The pitch shot
In order to hit a solid shot from your pitching wedge when you are 80-to-100 yards from the green, you have to learn to swing down on the ball to make it fly high. Take your club back with a full back swing, shift your weight forward and come down on the ball. Make sure you hit through the ball and follow through. A well-struck pitch shot will fly high and come down softly. Once you learn how to hit your pitch shot, you should be able to land the ball within 20 feet of the flag. Alternatively, adding some backspin to short pitch shot can cause the ball to move very little after landing, a technique used to set up accurate putts.
The chip shot
Learning to chip can be a very effective tool when your are within 50 feet of the green. Instead of trying to pitch the ball high in the air and having it land softly, you will bring the club back to your knee and strike the ball without breaking your wrists and stop your swing by the time the club reaches mid-calf. Your ball will jump in the air and then bounce and roll toward the flag. The chip is an excellent shot to use when there are no hazards -- water or sand -- between your ball and the flagstick. It works especially well when you are hitting uphill toward the green.
Use your pitching wedge when you are just off the fringe of the green. Line your shot up as if were a putt and then stroke the ball in putting fashion. Since you are using a club with a loft, the ball will hop up in the air at the start and then come down and roll the rest of the way toward the flagstick.
