Executing the Sequenced Release

[Jeff]

Daryl - you made number of statements regarding SG's swing

That his right wrist was upcocked at the delivery position.

That he must have therefore have a 10-2-D grip - based on inference rather than based on observation.

That he was obliged to use angled hinging in the followthrough because of his right wrist hand positon at the delivery position.

Here is a swing video of Sergio Garcia's swing.

Here are capture images from that video.



Image 1 shows the end-takeaway - that doesn't look like a 10-2-D grip to me.

Image 2 doesn't show an upcocked right wrist - from my perspective.

Image 3 and 4 - shows the release swivel phase and how left wrist uncocking precedes release of PA#3.

Image 5 and 6 - shows horizontal hinging action in the followthrough.

but isnt the hinging noticed at both arms straight, thus image no.5 showing angled hinging? image 6 is past that point imho.

That's a good point. Its' my impression when studying the swing video using my swing analyser program that the back of his left hand is moving vertical to the ground during the followthrough (rather than being vertical to the inclined plane), but it is seems that there is less external humeral rotation of the left humerus per unit time than one would expect if he had a more pronounced horizontal hinging action.

It could well be that I am wrong and that he is really using angled hinging.

Hard to say particularly with the plane angle that Sergio swings on . . . the flatter the plane the slower the face rotates for a given amount of roll.

That's another good point - the amount of roll required to complete a horizontal hinging action depending on the flatness of the clubshaft's inclined plane.

My main point is that I cannot personally identify a necessary causal connection between a golfer's right wrist/hand position at the delivery position and his ability to selectively perform a horizontal versus an angled hinging action in the followthrough. I also don't think that it makes sense to debate whether the right wrist is level or upcocked at the delivery position if the golfer employs a late release action where the right wrist is maximally dorsiflexed at that late release time point.
