This is how you throw a splitter: grip the ball like a forkball but not so deep in your fingers. By holding the ball in your fingers you use more finger force. This is very important in throwing a splitter.

 

This is how you throw a knuckleball: grip the knuckleball with your knuckles. The knuckleball is not supposed to spin very much and moves from side to side.

This is how you throw a sinker: grip like a curveball but on opposite seam. You turn your wrist to the left so your wrist is facing to the right. The sinker should spin backwards and will drop late and quickly.

 

This is how you throw a cutter: you grip it like a curveball but thrown much harder. It cuts away from a righty batter.

 

This is how you throw a change-up: you throw a change-up after throwing a Four-seam Fastball. It mixes up the batter because a change-up is a lot slower than a fastball. When the batter is geared up for a fastball you throw a change-up and the batter is way too early.

This is how you throw a slider: a slider is the third fastest pitch a pitcher can throw. a slider is like a curveball but when a curveball slants down and away from a righty, a slider slides horizontally away from a righty. Throw it like a mix between a curveball and fastball. Wrist break but throw it hard. Also lift your first finger slightly off the ball so the ball slides off your second finger.
