If you call it a rise ball because it is rising, I agree with you. If you call it a rise ball because it is thrown properly and has the correct low release point, with backwards spin on it and comes across the plate between the pits and forehead, it is a riseball. Just like most 10 - 12 year olds learning a screw or curve, that spins correctly, how much do most of them really break? In my opinion if a pitcher can get proper spin on their pitch, they have successfully learned the pitch. Next comes the years of practice to develop and make that pitch actually work.
My DD learned the rise ball very young because she was getting perfect riseball spin on her attempt at a screw ball, so we went with it. She threw that pitch for years and no, it didn't rise but we still called it her riseball. Now she is 14 and is throwing in the mid 50s so it is just now starting to work for her. Keep in mind even the Osterman's and Finch's of the world don't throw a true rise ball. The ball is thrown with an upward trajectory so any increase in elevation is due to the trajectory of the pitch not the spin actually making it rise. The spin does reduce the amount of drop the ball has and makes it drop less than a fastball, so the spin does combat gravity, but a human can not get enough spin and speed on it to overcome gravity and truly make the ball rise.
Too many people discourage young girls that can't throw 55+ from learning the riseball. Why? So it won't rise, she'll still get plenty of strike outs with it anyway and more importantly when she gets fast enough to make it work, she'll have been throwing it for years already and hopefully won't throw it over the backstop with the winning run on third base.
I'm in agreement with Hillhouse, other than a change-up the drop and rise are the two most important pitches there are. Why not learn them young? All this is assuming the girl can locate her fastball and has a good change.
