I was having my morning coffee and thinking about Brian Gays chipping method (with no left wrist cock) while looking at this photo from the sports section.
Nice wedges and a still level left wrist. Absolutely no flippy whippy, rubber wristed hand syndrome despite the fact it looks like a high soft floater.
And, with Horizontal Hinge Action (Clubface Closing Only / No Layback)! The giveaway is the toe of the Club pointing along the Line at the end of the Follow-Through (Both Arms Straight position).
