The TURNED LEFT HAND GRIP along with a FLAT LEFT WRIST.

Is this indeed a CLOSED CLUBFACE(CLUBFACE LOOKING TO SKY)?
Why do most good players that are in this position at the TOP(Trevino, Duval, Lietzke) actually FADE the ball?

This is a topic that should be addressed more. I'm fairly sure that Mr. Doyle actually says that the Clubface to Sky with Flat or Arched Left Wrist is OPEN, and vice versa. Of course many, many... most would say the exact opposite.

Of course whether one HOOKS or SLICES, depends a lot on how one brings the club and hands DOWN.
