Launch to contact is the right general idea. But.....most of the slop....the slack....in swings happens BEFORE launch. It happens between decision and launch. Once decision is made, amateur hitters have to 'make a move' before they can launch. They are not sudden. They have to 'take out slack' before they can launch.



Above.....very tight and sudden on the left...........loose sloppy arms on the right.

Watch....FEEL....the rear humerus action. It tells the story. Very sloppy....slack filled....on the right.

Cabrera's rear humerus moves a bit....but not independently. It 'is moved' by the action that fuses the torso into a unit. Colabello is independently 'working his arm'. Two totally different actions. One VERY high level. The other VERY amateurish.

This clip is a very good illustration of the existance of slack/slop, that has to be removed BEFORE one can launch, which means it must happen BETWEEN decision and launch. Therefore....the problem actually exists BEFORE launch....not between launch and contact.

Ever rung a church bell? The slack in the rope has to be removed first. If you haven't....there is a delay between your decision to ring the bell and the actual ringing.

ONLY....SnF mechanics....get a hitter into a position such that the time from decision to contact is instantaneous. And....to hit top level pitching....instantaneous is required.

The slack/slop in amateur hitters is almost always centered in their arms. They have not fused their torso into a unit....such that the torso pivoting over/around the ball of the rear femur....and the hand pivot....(not the arms moving the hands)....are the only moving parts.
