2. If you alternate between slicing and pulling the ball, you're swinging the clubhead from outside the target line to the inside.
FIX: Take your normal setup and place a shaft in the ground eight to 12 inches behind your ball and four to six inches outside your target line. Angle the shaft to match the lie of the club in your hands. Your goal is to swing under the drill shaft as you make your way back down to the ball. This will force you to swing more from the inside. The ball may fly to the right at first, but if you keep making the same inside-out swings and feel the toe of the club passing the heel as you swing through impact, your shots will straighten out.
