If you are consistently pulling the ball to the left we have to look at two things. Path and clubface. The clubface is going to have a tremendous effect on two things, the curve and the initial starting direction of the ball. The path has only to do with where the ball will tend to start. The clubface can override that. If you are coming down and the clubface is shut as you start down into the impact zone as I hit the golf ball it would tend to go to the left. If you look at it this way my club is coming down shut, as I hit the ball it is going to go to the left. That is really important to understand. Clubface control, you can do some drills if you are pulling the golf ball, thinking of the clubface on the downswing. Try to get the toe back a little more as you start down. That can be for the more advanced player. The average player is going to pull the ball because of path. What they do is start the downswing with the shoulders. The shoulders start the downswing and that throws the clubhead out. I am in pretty good position at the top here, I start down with my shoulders and that allows me to swing the club too far to the left. That will start your ball left of the target. The pull can be from two things, clubface or path. If it is path then you have got to work on some counter measures. For example letting the club drop more to the inside consciously. Actually a little loop to the inside. You can divide your ball in half by the black stripe on the range ball and really concentrate on hitting the inside quadrant of the golf ball. You can put a club down on the ground pointing to right field and really work on swinging that club down more from the inside. For most people, the average golfer, the pull is going to come from the shoulders dominating the downswing. For the better player they might have that clubface a little closed and trap the ball and hit it straight or with a little draw to the left with a ball that goes way to far over the green as well. So those are the two things, I hope that helps you.
