This would appear to be a Non Auto Left Wrist Throw. Does it have anything in common with the Mike Austin "power throw". Where is it different? Is it a "powered" throwout albeit in line with what CF would do, or a tipping point deal, a mere trigger to CF throwout. Did Homer describe a "powered" Swingers throwout of #2 angle, an "active" hammering so to speak?

Whatever the heck it is I love it and remember fondly the day Lynn taught it to me (at the Swamp, Bagger was there too as I recall). Id say it's primarily a Swingers thing, Left Wrist Throw from my personal experimentation but I have a bud who does it with his Right Hand or so he says, he is for sure more Simultaneous in Release.

Caution, no attempt at editing for brevity. Stream of consciousness follows.

Well, O.B. here's an example where the vernacular sometimes throws us off.
A "throw" is a release trigger whether it has any power behind it or not. Some of them really are "throws." They're usually used two or more together.
Lynn asked Homer "Why do you call it a throw?"
In typical fashion Homer asked "I don't know, what else would you call it?" which is like a lot of the vernacular. What else would you call it?

The left arm is inert. It gets pulled or pushed, it doesn't do anything by itself. The left arm is moved by either a shoulder throw pulling it or a right arm throw pushing it and the club.

Wrist uncocking is entirely CF, there's little advantage in consciously trying to uncock it, for a swinger and it's difficult to time close enough to impact. The hitter's straightening right arm uncocks the left wrist and controls the roll of the hands just to vertical left wrist for impact, no farther. Same with the swinger, the roll control. From then on there is no actual motion of the hands or wrists, it's just keeping the left wrist perpendicular to one of three planes, horizontal, vertical or angled until the left forearm finish swivel as the clubhead gets higher than the hands and the left elbow bends down. Like thumbing a ride to the stars.

What Lynn is demonstrating is a CF or gravity uncocking, and it's in line with the left arm. He calls it a vertical plane of motion. But of course, vertical references only the ground. So we have a little problem finding terminology for a cocking/uncocking motion always in line with the left arm when it's lying on the face of the plane. But that's what is meant. Vertical plane of motion on a slant. Heh. They're never out of line, no matter where. That's the beauty of that. (What else would you call it?)

Yes it is a swinger's move, it's done with CF because that's what swingers do, manage CF and the release must be sequential because you're uncocking on a plane and you're rolling to vertical wrists. The hitter can do them simultaneously and gradually. The hitter manually overrides CF but must be especially watchful for throwaway. It's hard to do. It must be constant, smooth acceleration or CF will take over. A short backswing and you have to wait until the right shoulder and elbow get close enough to the ball or you'll run out of right arm bend and throw the clubhead away. Then you can right arm throw.

Your bud may be hitting. But if he is swinging with the right arm it is a swing and is done with the shaft turned onto the sweetspot plane so it must be sequential release. And he's using a "pitch elbow" down in front. Tom Tomasello demonstrates a right arm throw on plane with a "wrist throw" we'll get to in a minute. I have a right arm swinger who delays the release and really whips at it. Hits it a long way but self-taught. Admires Retief Goosen, naturally, who's said to be a right arm swinger.

Mike looks to me to be a normal swinger with delayed release of a shoulder throw combined with a wrist throw, who lays off the shaft in startdown. As I said, that certainly gives you the feeling of throwing it a round the circle and Mike had a feel vs real problem.
If he's adding right arm into impact it may be a hit or a right arm pull but he is sequential release. He did not go into details of why he said throw it around the circle.

A swinger normally uses a shoulder turn throw and when that acceleration subsides the left arm is thrown off, with either a wrist throw or a delivery path throw if the wrist throw is too difficult to time (automatic at end of hands' delivery path, a snap release).
The hitter uses a right arm throw and delivery path throw, not a wrist throw as it's sequential.
Defs:
Hand Throw from the top, very hazardous except for the most well-educated hands, includes any hands-only putting stroke.
Right arm throw, a hitter's throw but not exclusively. TT used it for right arm swing which is similar to a hitter except with loosened wrists and on plane swivel somewhere in the backswing, and a sequential release, uncock and then roll to vertical.
Shoulder Turn Throw, swinger. The right shoulder is the last component of the pivot and the first component of the power package. It's the fastest in the chain, building on the feet, knees', hips' acceleration in order. Each have to subside to pass the baton on to the fresh runner. The shoulders pull and throw the left arm, down and then out.
Delivery Path throw, wherever the bottom of the arc of the delivery path (hands), long or short arc triggered automatically. Used with either right arm or shoulder turn throws.
Wrist Throw, the right hand remains palm up to the plane until release for a sequenced release, automatically or triggered non-automatic by initiating hands roll early before the end of the delivery path line.

That's it. Don't know what Mike Austin really did except he got his right shoulder very low (which should be aimed on the turned shoulder plane right at the ball) and he kept his hands at the right shoulder for a very long time. That to me is delayed release, because the right arm controls roll into vertical for impact, tethered by the left arm, and the right arm cannot straighten until the hands leave the right shoulder..
So aim the right shoulder at the ball and keep the hands close to the right shoulder as long as you can if you want to swing like Mike. Pivot provides balance and clearance and all motion must start with the hips.
