DD's opening front shoulder.

The rotational aspect is in the core. I said this already. The swing is a transfer of momentum into an object.

As far as being perfect, that’s what hitting is. When cracking a dish towel I am actually very accurate because the end of towel will go where I released or deceled the towels lead end. If your thinking is get the barrel on plane early and leave it there as long as possible. That is not what good players do. Getting the barrel on plane early is early commitment and is detrimental.

The hands should get on plane, with the barrel above the hands until it’s time to release or commit to the ball.



Notice how the core rotates back while the hips move forward in space. That’s the power source. Momentum and torque while leveraging the ground.

Like Aimee actively stretching the obliques against the hips, grandal is using momentum to stretch the obliques reactively against the hips.. If done sequentially it will be done reactively.

If you can feel this move and insert it into your swing. You will understand why the shoulders GET rotated and we are not trying to rotate them.

In all honesty. Try doing this. You will feel a ton of torque and no need to actively rotate the shoulders.

What your promoting requires perfection. I promote a swing that has built in forgiveness requiring less perfection. Get the bat in the way of the ball and swing for the fence.

How do you rotate your shoulders actively vs passively? Is someone doing it for you?

Do you know Mankin's material.

Yes. I like the drill where you turn the top hand so the thumb is down and then push the barrel rearward while pulling the knob forward (more like resisting the rearward push) Great for early bat speed and the barrel TUUUURNNNNS!!!

I didn't move the goal post. I just don't believe the hands or forearms swing the bat.

Fine. That is your opinion and you are entitled to it. I personally feel the hands/forearms play a role.

Mankin teaches the same things you mention in your post. I figured you believe in the same thing Mankin does when it comes to how you transfer energy into the barrel.

It actually is way more forgiving.

The shoulders get rotated by the core JUST LIKE AIMEE !! Remember ? You forget so quickly.

What you want is a spinny back the ball up and turn the barrel as fast as you can. Inefficient force production Bobby. It’s not what the best do. But I think you know that.

The shoulders are actively rotated by the core; the only way the shoulders can ever be rotated. There is no other mechanism.

You may say it's my opinion but I'm curious what the hands actually do and what hand muscles are involved with swinging the bat?

I'll grant that the forearms have muscles that could be used; the radial action is controlled by the supinator and pronator teres muscles. But the centripetal force of the shoulder rotation is a more dominant force and the radial action of the forearm is a more passive action like a hinge.

Swinging to a spot is more forgiving than swinging on the ball path? Whaaaattt?
What's a "spinny back the ball up"? And why would I want one?
And what's wrong with bat speed?

Lol. Committing to the ball later is more forgiving. Being able to hit through a big zone is more forgiving. If you put the barrel on plane early, you cannot adjust the barrel it will be in and out of the zone early.

Backing the ball up is only hitting it deep in the zone. Thats all one can do if your putting your barrel on plane early. Not to mention the outside pitch is harder to stay through. Forget about offspeed as well. There is little to no adjustability with getting the barrel on plane early. Plane the hands, keep the barrel up.

You're misinterpreting early. Get the barrel on plane early in space, but later in time. Getting the barrel on plane early (deep) allows you to swing later, commit later, and keep the barrel on plane for a longer distance.

Adjustability is not required because you can see more of the pitch and commit later + Timing offspeed is less of an issue because the bat stays on the ball path longer + Faster bat speed = The less need for perfection.

As for adjustabilty, are you saying with a crack the whip swing you can change the target of the swing after launching the swing?

Keep the barrel up and you'll swing down across the path of the ball. Less than perfect timing will result in pop ups and ground balls.
