9 degrees per segement... approxamitly, and there is about 5 segements. L1-L2 L2-L3 and so forth

I talked about lumber rotation because there are those who talk about the " stretch" or seperation between the shoulder and hips.

In relation of the whole body to the ground? is that what you mean? In that case I believe an MLB swing has the center around the back hip. Average hitters swing around the front hip leaveing a linear component- the bat must go forward before it turns, leaving a loopy swing. Haveing a short swing leaves you a chance to change it to a loopy long swing in case its a change up breaking ball. - Manny's reaching out over the plate home run.

NO, 9 degrees through the entire lumbar spine! Which btw is 5 vertebra. Its about 2 degrees per segment with 1 degree at L5-S1.

As far as our axis. We could debate all year. Perhaps the front leg is the best ref. as the axis but then it will matter how much the hitting is flexed at the hips. We dont have a solid ref. point here since there are so many joints that change angles.

I really think we try to make this too exact.

Shoulder and hip separation is going to be the product of thoracic and lumbar rotation.

We have a twisting/torque of the spine as well as actual rotation of the spine around a axis.

Getting back to the original post. I think a long swing is the hands getting farther away from the body. This will decrease bat speed. Look at MLB players at connection. They usually still have both elbows bent and hands in close as opposed to full extention of elbows and hands out away from the body.
