More amateurs than not come to me slicing their golf ball and one reason is a golf swing that is much too steep. That is, their arm swing is too vertical and needs to be somewhat more horizontal. The first thing I will do is take them to a sidehill lie with the ball several inches above their feet. I’ll ask them to swing more horizontally; if they don’t and return
to a vertical format, very “fat” contacts will result. Once they start making more horizontal or circular motions, they begin to produce less slices, more straight balls, and even slight draws! .
