Echoing JJ & Ken - gravity - it's the law. I think someone has linked the NASA simulator on what it would take for a rise ball to overcome gravity and the velocity and spin rates are well above what any human has thrown to date.

The simple answer: gravity. A riseball has to overcome it. A curveball or screw does not, and a drop is helped by it.

I don't have the exact figures, but the physics geeks have done the calculations showing how fast a softball would have to spin backwards in order for it to overcome the earth's gravitational pull and actually jump up. It was some number well above what humans can throw.

Edit to add:

I found this with a Google search. According to the authors of the book, for a BASEBALL (which weighs less) to rise above its anticipated trajectory it would have to have 3600 RPM (60 RPS) spin when thrown at 90 mph. RevFire says 25 - 30 RPS is an exceptional spin rate - puts you in the elite category I believe. And the fastest female pitch speeds are in the 70-73 mph range. So you'd need a softball to be thrown roughly 15-20 mph faster with twice as much spin to get the ball to actually jump. That's if it weighed as much as a baseball. Since it weighs more, you probably have to increase both numbers. You'd probably have to also account for increased drag due to the larger surface of the ball, and the shorter distance to make it happen. So not bloody likely.

That does it for me. Case closed!!!

I do understand gravity. So you guys say that it is impossible to put enough spin and speed and whatever to make a ball curve/rise upwards in a short distance (43'). I also realize it will return to earth sometime. I am not a rocket scientist but with enough speed and power you can over come gravity and get a rocket to the moon. I'm just saying. If the consensus is there is no rise ball, why is that all I hear on the TV broadcasts about the great rise ball so an so has. If it is just an optical illusion ( and it well may be), then is the curve and drop also, or are you saying that gravity helps them. I can't argue with that. Thanks for letting me ask these novice questions.

Drop- gravity helps
Rise-Gravity hurts
Curve- Gravity turns a blind eye and says its doesn't give a rats rear
Screw-No such thing so it doesn't matter.

As for consensus...there is none, on any topic, ever, on DFP....we could literally disagree on whether or not 1+1=3. But we all agree that whatever Dallas Escobedo was throwing in college wasn't actually a riseball.

NEXT QUESTION. As a novice, does (rise ball) have a spin altogether different than any other pitch? If so, when a pitch starts out low and is heading high why does any body swing at it, won't it likely be a ball. Seems like most the rise balls I see on TV are way up there. Is it the different spin you see as it get closer that causes the optical illusion? I thought softball was ...see the ball, hit the ball, catch the ball! Wow am I getting an eye full (no pun intended!) That's all for me, thanks again, you guys are great!

So... ball travels from point A (release point from pitcher's hand) to point B (catcher's mitt) WITHOUT rising, meaning without traveling in an upward trajectory? Definition of the word rise:

1. move from a lower position to a higher one; come or go up

Okay, then what you're saying is that from pitcher's hand to catcher's mitt the ball eithers travels completely level or on a downward trajectory. Those are your only other options. Good luck with that.

it does have a different spin, it has a tilted backspin (ideally straight backspin but no one really throws it like that with any great velocity) so it "floats" and does not have the natural gravity drop that is ingrained in every players head from seeing 10000000 balls in flight without this spin. Couple that with the fact that it is released with a body angle to disguise it by releasing it lower than a normal pitch so it can be thrown low to high and players miss under it or pop it up. As for reaction time...we are talking about .4 seconds from release to the ball being in the catcher's glove....figure the swing from launch to contact takes roughly half that...that gives precious little time to distinguish it from a pitch coming it at the waist or rising to the eyes. if a pitcher can make it appear like a waist high pitch for the first 20 feet or so then game over, it will appear like a strike at swing launch to the batter.

Now couple that with a drop ball and the pitcher is deadly as they look the same for about 20 feet and then one goes north and one goes south.

and away we go...the great "rise" as defined by starting and ending points vs "rise" as curvature upward....

by your definition there would be no difference in pitch between a riseball thrown with backspin and a dropball that misses high.

I don't think anyone debates the starting and endpoints as being low at release and higher when caught, the shape of the curve in between those points is the crux of the debate.
