In another discussion people were chatting about taller pitchers.

Debbie Doom, UCLA, pan american team and olympic team USA
is 6'5".
When facing her, pitching rubber at 40',
Her front foot would land on the pitching circle chaulk!!!
Eventually erasing it.
At times stepped beyond it.
As a hitter would see a giant cleat comming at you....then the ball...

Her pitch release was EXTREMELY LOW. we used to joke she scrapped her knuckles some time. Literally released 8" inches off the ground.
Incredible pitcher. Think of 6'5" rotating ball over her head and releasing it nearly 8' feet below!!

*Never throw anything up to
Lisa Fernandez... she's on the tall side ;)

Hey I meant to mention before that I am pretty sure you have seen more pitchers release more pitches than I have so I am definitely not doubting you!

And if Debbie Doom isn’t the coolest name ever for a pitcher, I don’t know what is.

I think the above is a great piece of info. People get freaked out with the “flat bat” wording but it’s dead on.
A team I worked with did this to a pitcher. She had a great riseball, but she was lazy with hiding it. It was very easy to know when she was going to throw it.

So, we instructed the weak batters to take the pitch unless there were 2 strikes. We worked with the strong hitters on hitting riseballs. We got a great outing from our pitcher, and we beat them 8-1.

I felt a little sorry for the kid....she got frustrated, and started throwing *more* riseballs.

If you take a rifle that is aimed parallel to the ground, shoot it and drop a rock at the exact same moment, which will hit the ground first, the bullet or the rock? Excluding the friction of the air they will both hit the ground at the same time, gravity affects both equally.

Gravity will add velocity to a drop and subtract it from a riseball. How much would be an interesting physics problem, I think it would be measurable. It seems to me that my pitchers record their highest speeds on low pitches.

What is very interesting and is never discussed is whether the brain implcitly takes the affects of gravity into account in visual perception and it's projected trajectory of flying objects. Common sense and science agree on this, yes it does. Imagine trying to catch or hit a thrown ball in a low G environment, the ball would not 'fall' at the same rate that it normally would so of course it would be challenging.

Yes interesting physics question...
How it relates to helping/hindering pitches!

For the math guru's perhaps use
Spin rate 25rps.
Pitch speed 65mph.
Or?

There are couple others pardon forget your user names.....

The contribution of gravity could easily be figured out by removing the gravity term in Eq. 7 (-mg) in the paper and then integrating the equations (Eqs 6-8) and comparing the curves to those given in the paper. Gravity is always present however (if we are playing on Earth) so I am not sure what the point of that exercise would be :LOL:
