? what is that sentence ?
"the rise ball does not rise above the original trajectory of the pitch" your saying its released on a path that it stays on.....
* the pitcher releases the ball at their knee and can end up at your shoulder or lower.
A riseball may cross the plate at a higher elevation than it was released, but even a really good riseball spin cannot completely defeat the forces of gravity. A rising trajectory would mean that it curves upward - this doesn't happen. What can happen is that the brain is expecting the ball to fall at a certain rate, and when it doesn't, so the brain adjusts and gives the sensation that the ball "hopped" upward.
