An article called “The Science of Square: Understanding the relationship between the wrist and the club face,” about the wrist action during the swing and what happens when you change conditions from address to the top, and how that affects the club face. In addition, I suggested that the average golfer plays from a more square condition at the top, rather than one that is radically shut (i.e. Dustin Johnson). I did not say that the average player could not play from a slightly shut condition, but remember, compensations have to occur.
However, there has been a growing number of better players who have had wonderful success playing from conditions at the top that range from slightly shut to super-shut. Think about the swings of John Rahm, Justin Thomas, Brooks Koepka, Tony Finau, and Dustin Johnson at the top.
So in this article, let’s examine the shut club face position at the top using Hack Motion’s Wrist Sensor so you can see how the wrist action changes when this type of position occurs during the swing. I took a few sample swings with the new “modern” swing… slightly stronger grip working into a flexed lead wrist at the top, which causes the shut face at the top like DJ. Here is what we saw…
At address we see that the wrist in the stronger position possesses 32 degrees of extension, or cupping at address, which is common with stronger grips showing more knuckles.
