On page 29 of Dusty's "You Can Teach Hitting" he says: "Throw the head of the bat at the ball. To do this, the hitter accelerates his wrists, forearms, hands, and fingers and throws the bat through the strike zone. He should think of this as though he were cracking a whip".

If the mechanics you choose separate the lead arm from the body, do not attempt to apply early torque (tht) to the bat. Serious wrist binds can develop and place a lot of stress on the joints and spinal column.

A batter will never develop sufficient arm strength that can generate the bat speed necessary to become a great hitter without properly using the rest of his body. The more the batter attempts to use the arms to accelerate the hands, the more he separates the arms from the power of the rotating body and shoulders.

Great hitters do not separate the lead arm away from the rotating body by extending the top hand.. In fact, far from it, great hitters keep the hands and lead arm back (across the chest) and allow the powerful rotation of the shoulders to bring the hands to the contact point. --- The top hand is not driving the lead arm away from the chest (this is forward arm extension and linear mechanics). As shoulder rotation starts to accelerate the lead arm and hands around the arc – THE TOP HAND IS PULLING BACK TOWARD THE CATCHER. This “pulling back” not only applies tremendous torque to the bat, but it also keeps the lead arm extended across much of the rotating chest as the swing is initiated.
> > > > > > > > >
> > > > > > > > > > As the swing continues, the back elbow will lower to the batter’s side and top hand will stop pulling back toward the catcher, and back arm will rotate with the body in the classic “L” position. The lead shoulder continues its rotation, which pulls the lead arm around the arc and back toward the catcher as contact is made. It is the “pulling back” of the lead arm that causes the “fishhook” effect (reducing the arc radius of the hand-path) and adds bottom-hand-torque to the bat. --- These are the mechanics of the great hitter that result in a highly accelerated bat through contact.

It is fine to own and read that material for a general understanding, but I submit to you that those are not the mechanics used by great, All-Star caliber hitters.

After a number of swings and misses (getting the rust off) I realized I was swinging my arms at the ball. Applying your lessons, I tried to get a full hip, then shoulder turn into my swing. Two things happened - first, (and I clearly remember this) I was fully facing the ball, body completely open, and the ball was still 5-10 feet in front of me (I had been late on previous pitches)(it felt like the pitch was a changeup); second, though I never consciously tried to swing the bat, the bat seemingly flew into the ball. I found myself crushing ball after ball with minimal effort.

For that reason the batting cage is poor training. You weren't getting the "getting the rust off," you were learning where the pitches were going to be.

Since both hands are on the bat next to eachother its impossible to straighten your back arm. It must stay in an L position. Don't take my word for it. Try it.

> > > > >
> > > > > Thank you. You said "there really are an infinite number of ways you could execute Dusty's advice" and although you didn't exactly say so, I infer that you believe this could be done in a manner that is still compatible with Jack's theories. Could you please explain one or two of these ways this could be done (executing Dusty's principles) and still be compatible with Jack's theories? Thank you.
> > > >
> > > > Dusty's description omits anything that necessarily encourages/overemphasizes extension of the arms,which is one of the major points Jack made above.If you prematurely extend the arms allowing the hands to get away from the body's center of rotation(if you don't keep the hands in) you will kill the swing.
> > > >
> > > > You can do just what Dusty says and it can work IF you have a circular hand path,turn the body around a stationary axis and torque the bat between the hands throughout the swing.If you do this,the energized torso will rapidly "accelerate the forearms hands and fingers" that are tightly connected to it.As the bathead is fired out of the arc of the circular handpath the body's momentum will transfer into batspeed and pull your hands along with the launched bat which may feel to you like cracking a whip or firing a projectile or achieving escape velocity or whatever you want to call it.However,this should not be confused with the reality of the physical principles of whipping.Throwing a ball is much more like whipping where you turn the body(lead with hips/torque separated upper and lower body to start momentum transfer)but then you bend at the waist and whip momentum through the arm with sequential extension-in other words you want to extend the arms before you snap the wrists.
> > > >
> > > > In hitting you stay more upright and "maintain your spine angle" or body posture as you rotate.Torquing the body is similar in the early part of hitting and throwing,but getting energy to the bat requires using the arms to connect the hands to the torso and drive hand torque to fire the bat.The arms must not extend before the bathead fires.The wrists torque(not snap)BEFORE the arms extend.This part of the swing which Jack describes as "transfer mechanics"--this both arm/hand action-- is an entirely different sequence and action as compared to a single arm throwing action and has nothing to do with the principle of whipping.

Having always hit w/ linier mechanics I always felt a strain on my wrists after the bat went through the zone. After experimenting with rotational I nolonger felt any strain and my swing was effortless. Without sounding like a shill for Jack, Rotational mechanics improved my swing.

Shawn-

One important factor is when the lead arm extends.Lead arm extension means the hands(and center of mass of hands/arms/bat)are getting away from the body"s center of rotation.This is a hard to control trigger of momentum transfer from the body.If the hands get away before lower body energy has been "whipped" rotationally up into the torso,there will be little energy to generate batspeed.If the lead arm extends before the hands have torqued the bat a considerable way to extension,then the energy transferred will go more to dragging the bat along its axis instead of turning it to create batspeed.Lead arm extension is suboptimal between "launch"(torso starting to turn forward)until just before the bat becomes fully extended.
