Grip the ball with your index and middle fingers across the seams, with the thumb underneath for support
Hold the ball deep in your hand to help create the screwball spin
Use a throwing motion similar to a fastball
Rotate your forearm inward as you release the ball
Turn your wrist so the thumb finishes pointing down and inward
Release the ball with pressure from the middle and index fingers
Follow through naturally after release
Keep your arm speed consistent to disguise the pitch
Practice the grip and release slowly before throwing at full speed
Avoid over-rotating the wrist to reduce stress on the arm
