I have read all the batspeed and swing mechanics articles on this site and I tend to agree with most of the research. However, I would like someone to explain if the exact same batspeed can

I've seen plenty of people who can generate great batspeed....85+ Mph, but couldn't hit very far, unless they hit the ball way out front and pull or push it. I've seen people look effortless at 80 Mph or less and hit bombs regularly. The difference is that the great hitters get to that speed prior to contact, the poor hitters get that speed at post contact. Taller people have longer limbs as well and with mechanics that are executed correctly, the arc of the swing would be longer creating more speed on the end. Think of a ball on the end of a string.....The longer the string the faster the ball will go when it's released.

Look at how long John Daly's swing is. Now I'm not advocating we preach length......but when your limbs are longer (and the mechanics correct) you have no choice. Tall guys anatomically should have an advantage in batspeed, but their strikezone is larger and that's the trade off.

The smaller kid may have greater batpseed but not at ball contact where it counts." What studies and by who? And you say "You would have to get a device to measure their batspeed to find the answer." It would seem that these "studies that have been published" should have "a device to measure their batspeed to find the answer."

It seems that all anyone can do is SPECULATE that there are various reasins why the big kid will hit harder than the smaller kid, but much of the speculation looks for/presumes DIFFERENCES in the big & the small kid to explain why the big kid may hit harder than the smaller kid.

The question is: if there are NO DIFFERENCES in mechanics, bat weight, etc between the big & the small kid, and the ONLY difference is size/muscle/mass, etc, will the bigger kid not have the advantage? If you had a 12-year old kid who has EXCELLENT mechanics up against an 18-year-old kid who has been sucessful but has only AVERAGE mechanics, will the 18-year-old not have the advantage?

One is 12 years old, weighs 110 pounds and uses "rotational" mechanics. The other is 18 years old, weighs 200 pounds and uses "linear" mechanics. And so as to not allow someone to try to complicate the question with experiences in handling the pitch speed factor, let's stipulate that the pitch speed is 60 mph. Who would fit the ball farther?

Coach, I think you are missing the point, which is there probably is another element to power (in baseball) besides batspeed, namely the size & strength of the hitter. Whether these studies were made in golf or not, I don't know and don't care, but I do know that these studies have not been made in hitting.
