The opposite of the rise is the dropball. That's a pitch that's going to spin over the top, or spin
forward, and move from high to low. It's almost like an overhand curveball in baseball.

Dropball grip is where you put all your three fingers over the top of these seams, thumb
opposite of the middle finger, and you work on snapping the ball so you get a downward
rotation and the ball moves down through the zone.
