Jack-

I think the front leg and hips open when the bat starts to turn back toward the catcher.

This movement is synched by the lower body following the lead of the upper body, specifically, the back arm and lead leg externally rotating together and then the lead arm internally rotating as the back leg stays internally rotated,turning open as the hips turn.

The hips open and the bat turns and the shoulders stay back between the two during prelaunch torque (body coils to about 15 degrees of hip/shoulder separation/xfactor accoring to Zig's motionanalysis) then continue resisting/staying back by tilt at initiation (with additional 12 degrees on average of xfactor "stretch" according to Zig
s measurements).
