Pitches don't suddenly move or change speeds! Physics dictate that EVERY pitch (except, and then only on rare occasion, a knuckeball) follows a smooth trajectory (i.e., there are no sudden drops, rises, or breaks) with the velocity decreasing gradually following release from the hand (i.e., there are no drastic changes mid pitch). If you're really interested in the physics, use the DFP search function to find posts by POBguy.

That was pretty well debunked as all his data shows the relationship over distance, not time. When he finally plotted the pitches by time the result was different.

Doesn't matter on either to me really. I know I see pitches break, I see drop balls fall off tables, and curve balls take 90 degree turns! Three letters debunk all of it, MLB.

My DD throws a flip change. It's her best pitch. According to the rev fire it is also her fastest spinning pitch. I think the last time we measured spins was 2 years ago before she went to college. Change spin was about 26 revs per second. All her other pitches were around 18-22.
It does float sometimes but to me it only makes the pitch more effective. It's like a bugs bunny floaty pitch. Btw..That's a technical term. Anyway, I love the flip change.

Coachmom,
My dd also throws the flip (14u). It is a great pitch for her also, but I was always under the impression that you didn't want much spin on a change - more stiff wrist, etc. Does getting more backspin on that pitch make it more effective? If so, how do you get that much spin on it? Not palming it as much and using fingers on seam? Would like to work on this more.

Hi catchermom, I am sure some of these pitching experts on this board will be able to answer your question better than I can. I know she uses her fingers across seams like a 4 seam fastball. She does not palm it much at all. Her wrist stiffens a bit on the finish as she flips it out of her hand and lets it roll off the fingertips. It spins almost perfectly backwards and fast enough that it is very hard to tell the difference between it and a 4 seam fastball spin.

What??? That's not what I got out of those discussions! Sure the amount of break may increase at later times, but there's no drastic change or instantaneous break i.e., all pitch trajectories are smooth.

Don't you mean riseball? A fastball typically spins the other direction with topspin.

What I mean is that the back spin fast enough it can be mistaken for the topspin of a fastball.
You almost cannot tell it's spinning backwards.
Hope that makes sense.
