Took me a while to figure this one out. Curveballs are real. The "break" is not. The ball will travel on a curved trajectory from pitcher to catcher. Not a straight line to near the plate and then a break.
I disagree that there is no such thing as a rising fastball. Try it with a wiffleball (it magnifies all of the effects due to the light weight.) Spin a ball backwards fast enough at it will rise.
Not true, the forward velocity keeps the trajectory straight, as it nears the plate it "breaks" because of less velocity, and a build up of air on one side of the ball. That is like calling my curve ball at bowling a long curved trajectory...it breaks at about the 3/4 mark of the lane.
I new a guy with a tremendous “riseball” wiffle pitch, I don’t think I ever hit it.
