How to Pitch a Knuckleball Underhand in Softball

A strong grip on the seams is imperative when throwing a knuckleball.

Like its hardball cousin, a knuckleball in softball is an unusual pitch. Knuckleballs lack spin, causing them to move in unpredictable directions. Coupled with 33 percent lower speeds compared to a fastball, this makes the knuckleball an elusive pitch to hit when it is thrown correctly.

Instructions

1. Grip the ball correctly by holding the softball deep in the palm of your hand and digging your fingernails into the seam of the ball. Use all of your fingers and your thumb for a full, deep grip. There should be no space between the ball and your palm, with your hands forming a C-shape around the ball.

2. Push off the pitching rubber with your dominant leg (same side as your throwing hand) while stepping forward with your other leg as you start your pitching motion. At the same time, swing your throwing arm forward in an underhand motion.

3. Release the ball at belt level. Let go of the ball all at once, not letting any finger touch the ball any longer than any other. Upon release, all of your fingers and your thumb should be pointed directly at the batter and splayed. Do not flick, spin or twist the ball in any way. If done correctly, the ball will be released without any spin.

Tips & Warnings

• You can practice the knuckleball without a catcher. When a knuckleball hits the ground, it will roll forward only a small distance compared to other pitches. If the ball is rolling forward too much, you are adding unwanted spin to your knuckleball.

• Use the knuckleball as part of a balanced pitching repertoire. The knuckleball works best as a complement to a fastball. It is also useful against power hitters and on windy days in which the movement will be even more unpredictable.

• Use the same arm speed as your other pitches when throwing a knuckleball. If you slow your windup to throw the knuckleball, the batter will know it's coming.

• The knuckleball grip is unique, so be wary of opposing players looking for this grip at the beginning of your windup. Hide the ball in your glove as long as possible to disguise the grip you're using.
