Rise-curve
A diagonal break: up and to the glove side.
A Rise-curve flying to home plate in 3D, from the catcher's view.
What it does
The rise-curve tilts the axis between a riseball and a curveball, around 1 to 2 o'clock. It carries like a riseball while it sweeps to the glove side.
How to read it
It starts at the belt on the outer half and ends up high and away. Hitters see a riseball and swing under it, or see a curve and reach for it.
What makes it work
Backspin with a sideways tilt. It punishes hitters who sit on the true riseball, because the finish is a bat-width further away.
