They shift as they swing.
.
In terms of 'action' or 'energy production' or 'launch' or 'what the hitter actually does when'....the swing is over before the front leg firms up. The front leg firming is important.....it makes sure the rotation continues....and that the energy doesn't bleed forward linearly. So, it is important. But the swing is over.....before the front foot is weighted.....again....in terms of what the hitter actually does and when he does it.
The swing is launched from the rear foot/leg/hip load....the launch shifts the weight to the front leg which firms and ensures continued rotation.
At the same time of the rear foot/leg/hip unload/launch is the hand pivot/throw.
Just like a pitchers final rear foot/leg/hip launch move occurs as his arm unloads. They are synced together. They happened suddenly....together.
I hope I can pitch to your team waiting for the bat to 'flyout' like a weedeater. Not only will they be late....they will lack swing quickness.....they will not be able to direct the barrel accurately to the ball.
I can't imagine not using the hands to direct the barrel to the ball. Are you saying things just line up.....on their own.....to a 95mph fastball.....and/or a 75mph offspeed pitch?
You really aren't saying that are you
I have never seen a fastpitch player I would use as a model.
Might be out there.....I just haven't seen it.
I guess you're going to have to reread. I can't say it any clearer.
Or ask more specific questions.
Basically....as you pick up your lead foot to stride...you load up the rear leg/hip and then push from the rear foot and hip to unload the rear hip before the lead foot is down. This unload will put the lead foot down....which firms up and ensures there is no forward slide...that rotation continues.
At the same time the lower body unloads....the hands throw the barrel around the pivot.
Both unloads are together. The great hitters are very good at the syncing of these unloads.
Just like in pitching. The unload of the lower body puts the foot down. The arm unloads in sync with the lower body unload.
Sure enough....I went deeper into that sigy site and there she is.
YES that is high level.
Watch her and see if you don't see the swing putting the front foot down.
Actually....to be more accurate.....she launches the swing....from the rear hip/leg.........which is exposed due to the front hip clearing....and this launch
'weights' the front foot. The weight is shifted AT launch....not before.
At the same time as the above described lower body launch occurs....she clearly throws or pivots the bat in the hands. You can see speed in the 3rd dimension.
YEP....they ALL should imitate her.
But not Rivera
