How to Throw a Slider
Quick answer
A slider is gripped slightly off-center and thrown with fastball arm speed and a firm wrist, producing lateral tilt rather than the big top-to-bottom break of a curveball. Like the curveball, it is an advanced pitch that should wait until a pitcher has command of a fastball and changeup.
What a slider does
A slider is a hard breaking ball — faster than a curve with a shorter, more lateral break. Thrown well, it looks like a fastball out of the hand and then darts sideways and down. Like the curveball, it is an advanced pitch that comes after fastball and changeup command.
The grip and release
Grip it slightly off-center: your index and middle fingers sit just to the outside of the ball with a firm (not tense) wrist. Throw it like a fastball and let your fingers stay slightly to the side of the ball through release. Many coaches cue "fastball with a little tilt" rather than any wrist twist.
Pitch Smart Guidelines
Breaking pitches add stress — track limits and rest days.
Safety and sequencing
Because it's thrown hard with a firm wrist, a poorly taught slider can be tough on developing arms. Add it only after the curveball or under a coach's supervision, keep the wrist firm rather than snapping it, and don't overuse it in a game.
