Tom’s Featured Tip: Fundamental 3: Controlling Curvature 

Based on my research and study of the swing method principles that I teach, I believe that there are 3 True Fundamentals of golf:

    1. The ability to hit the ground in the same place every time and forward of the ball to insure clean contact. 

    2. The ability to create enough power or distance to enjoy and play the game. 


  • The ability to match the clubface to the swing path to control the curvature of the ball to keep it in play.


Last issue I addressed Fundamental 2 – creating sufficient power and distance to enjoy and play the game. 

This issue I’ll address Fundamental 3 – the ability to match the clubface to the swing path to control the curvature of the ball to keep it in play. 

The reason a golf ball curves to the right or to the left when it is struck (the wind is not considered here) is because the clubface was either open to the swing path at impact, creating a fade (left to right) spin axis on the ball, or the clubface was closed to the swing path at impact creating a draw (right to left) spin axis on the ball. 

If you match your swing path direction with a square clubface, the ball should not curve. 

The differential between the clubface position and the swing path direction at impact causes more or less curvature accordingly. 

Clubface positions: 

The swing path that I favor for most students is the In to Square to In swing path, also known as the Inside to Inside swing path. I favor it because if the student can nail that, then it’s a fairly straightforward proposition of getting the ball position correct for whatever curvature you want, providing that you keep your hand action neutral. 

With an Inside to Inside path, during the course of your swing you are swinging downward and outward until you hit the low point of your swing. At that point you are swinging straight and flat for a very short distance, then you are swinging upward and inward. 

To draw the ball, you might set up with the ball back from the low point of your swing (bottom image in the ball positions graphic) , with the clubface square to the target line (closed). That would mean that you would strike the ball at a point where your swing path was down and to the right, with a clubface that would be slightly closed to the path. That would produce a draw (with neutral hand action). 

Conversely, to fade the ball you might set the ball right at the low point of your swing (middle image in the ball positions graphic) with the clubface pointing slightly to the right (open). That would produce a fade (with neutral hand action). 

Neutral hand action means that you are not actively trying to close or open the face at impact. You are letting the hands make a natural rotation, nothing more or less. Excessive hand action can amplify either curvature and it brings an unnecessary element of timing into play, so use it sparingly. 

Your body aimline may need to be adjusted to allow for curvature, but your swing path should remain consistently Inside to Inside

If you review this information enough, you’ll truly understand curvature. That will allow you to correct errant shots, and to produce curvature on purpose when you need it. It’s worth a little study time and range time. 

Learn it, you’ll like it.
