【The Geometry of GOLF】 8. The Geometry of putting 　(1) Apply top spin

Have you ever heard in a putter lesson that you should hit with an upper blow and hit the face on the upper side of the ball to top spin? Actually, this advice needs to be careful. First of all, ”the face hits the upper part of the ball (above the equator)” can only be done by hitting with the corner of the putter face like ③ of above figure, or tilting the putter like ③ of Figure above. If you hit it like this, the ball will bounce at the moment you hit it. The putter has a loft of 3 to 4 degrees, and the ball starts rolling after a short flight in the air after impact. Therefore, hitting the putter on the top of the ball is not possible in reality. Next, regarding ”hit the upper blow to apply top spin”, as explained in Chapter 4, if the shaft lean is constant, the spin loft of the ball does not change regardless of whether the attack angle is down blow or upper blow. However, if you hit the upper blow with the putter shaft tilted to the left, you can reduce the backspin and it may be possible to apply top spin. Simply tilting the shaft to the left to reduce the impact loft is the same as reducing the loft of the putter, and since the ball does not carry in the air after impact, it may be subject to grass resistance at the start and might not roll straight. To create overspin from the start of your putt, you need to tilt the putter shaft to the left and hit the ball upper blow.
