> > >>> Jack,I think you misread my intent of the thread,the very 1st movements of the knob go from catcher toward opposing base of hitter,this is not a forward pull of the knob as I thought I have heard you profess.I believe that during these 1st movements the barrel is driven back or assisted in being driven back by the top of the bottom hand as the lead elbow works up,when done by a dominant right hand [lefty hitter,one that throws right and bats left or vice versa],the distinction and feel of bat being driven back is superimposed,but before the knob is ever pulled forward,I think by rotation,the hands are torquing but not just top hand pulling back ,but rather by a sophistacated,maybe double pendulum act of the lowe hand that drives the barrel back with the top part assisted by lead arm movement[elbow up] and then simultaneously the knob being pulled out and around to innitiate the chp ,but on a larger scale this is the finer points being created for swing plane while tilt allows the body to get into position for the fine plane adjustment to work,,by launch it is on autopilot and swingplane and radius has been set or is underway and not changing.<<<

That is one of the problems discussing a complex movement with the written word. I thought it might help if I showed a clip for reference in our discussion.

> >Jack what was nice to see in the clips you posted were adjustments made between the 2 for higher s lower pitches [the tilt] more for bonds on lower pitch,and the elbow slot adjustment with a more away pitch for bonds and elbow with a space between ribs and elbow.However the sosa clip you had with grids and the red lines that seperated plt and tht,I think,would be a better clip if you could post here.I think it would show the movements of the bottom hand and the 1st movements back and rearward of the bat.Then you could point out exactly where plt begins and ends and where tht begins.
Jack or Brian can you repost the clip of sosa with grids here or the game clip of ortiz[side clip] to re discuss the plt/tht points of beginning and end.
