When is the twitch ideally? Can the twitch be delayed? off speed? and what twitches?
Twitch ....
One thing I see in this clip, is the rear elbow drops/slots with the "twitch" action,
without the bat barrel/hands moving much at all in space.
Is this an absolute? or just something specific to Jr.?
When my DD swings, her hands are turning the barrel *AS* the elbow drops/slots - all in one motion.
To me, this phase of her swing looks "stiffer" than Griffey's...
(i.e., pulled by the torso-engine ... you may view that as the rear arm becoming slotted without the hands moving forward much) ...
