Re: Re: Re: Re: Re: Hitting Through the ball

>>> I have read the arguments pro and con about the above. Some say the ball stays on the bat 1/2000 second and hitting through makes no sense.
> > > > What happens if the player misjudges the exact contact point which most surely do? Is it possible to reach max acceleration to the exact contact point? Not likely..The mental cue of hitting through the ball might make no sense as judged by pure physics but accelerating through a wider zone does make sense in real life. Telling the players to "replace the shoulders" seems to get this done for me. Any comments? <<<

The swing mechanics used by the vast majority of batters do not reach max until the bat has rotated 50+ degrees past this point. That is why most of their longest hit balls are pulled foul and they have very little power to the opposite field.

> > > > Donny, I have nothing against “driving thru the ball” at contact -- as long as we understand that “thru” is only ¾ of an inch. That is how far the bat moves with the ball before the ball is gone. I think you would agree that reserving energy to accelerate the bat after that point is wasted energy. Would not that energy have been better used to accelerate the bat-head earlier in the swing?

The problem is, their transfer mechanics does not efficiently convert that shoulder rotation into bat-head rotation. --- Obviously, timing is a critical element to good hitting. That is why we require countless hours of batting practice.

> Someone said Driving through the ball to me has more to do with the direction of the force as opposed to the distance through the ball.It has nothing to do with direction of force, at least not as taught by me and most other instructors. It has everything to do with DISTANCE, "through" meaning aiming for a point shortly beyond contact so that the bat doesn't start to slow down prior to contact. Teacherman, if you are ever in the Dallas area I'll be happy to show you what I mean.

By direction, I mean the force/batspeed going to the point of contact. I see many, many swings that seem to be aimed for the spot the ball was when they decided to swing rather than the spot the ball will be at contact. If the force is in the direction of the spot where the ball is at decision, your batspeed will be late. If it is at the contact point, then you can cut loose and swing through the ball.

In other words, take a good aggressive cut. Then ask yourself, did the speed or force of that swing go through an imaginery batting T set up at your happy zone. Many times it won't and most of the time it has to do with the dirction of the swing as opposed to the creation of more force. You've directed it forward of the contact spot. And therefore, the swing is not at full acceleration at contact. And, if making an adjustment for an unexpected pitch location, it will actually decelerate to hold back for the ball. IMHO, very few swings are decelerated before contact on purpose. It's done because the direction of the force is wrong.

Which makes a point that many a bad swing is due to poor judgement of where to contact the ball.

If you're ever in St. Louis, I'll be happy to show you what I mean.
