Hello, my name is John Webster, Master Instructor for Jim McLean at the Doral Resort and Spa. As you know, great players do not keep one ball position; they move it around for various shots. Here is one simple way to make sure you know where the ball should be positioned for these different shots.
The Right Position for the Ball in Golf
Chipping and Pitching
For chipping and pitching, you step in with your right foot behind the ball, leave it there, and then bring your left foot in and forward just a bit. This keeps the ball back of center. As you walk in for a mid-iron, you step in with your right foot behind the ball, bring in your left foot in front of the ball, and then take equal steps back and forward with your left and right feet. Now the ball should be fairly well-centered.
As you walk in for a driver, step in with the right foot, bring in the left and take a big step to the right with your right foot, leaving your left in its original position. So just to review, for chipping or pitching the right foot comes in, stays there, and then you move in with the left. For mid-irons, right foot in, then equal steps back and forward with the left and right foot, and for driving, right foot in, left foot stays, and then a big step back with the right foot.
