Baseball Pitching Mechanics: Youth Basics

Building Sound Pitching Mechanics Early

Proper pitching mechanics protect young arms from injury while building a foundation for long-term development. Youth pitchers should focus on repeatable, efficient movements rather than velocity.

The Six Phases of Pitching

Every pitch follows six phases: wind-up, stride, arm cocking, arm acceleration, arm deceleration, and follow-through. Understanding each phase helps coaches identify and correct mechanical flaws.

Phase 1: Wind-Up

The wind-up establishes rhythm and balance. Youth pitchers should use a simple, controlled leg lift rather than elaborate movements that can disrupt timing and balance.

Phase 2: Stride

Stride toward home plate with the lead foot, keeping the hips closed as long as possible. The stride length should be approximately 75-85% of the pitcher's height.

Arm Action and Safety

The arm should follow a circular path during the cocking phase, with the elbow at or slightly above shoulder height. Avoid 'short-arming' the ball or dropping the elbow below the shoulder, which increases stress on the rotator cuff.

Pitch Count Guidelines

Ages 9-10: Maximum 75 pitches per game
Ages 11-12: Maximum 85 pitches per game
Ages 13-14: Maximum 95 pitches per game
Always follow rest-day requirements between outings

Common Youth Pitching Mistakes

Opening the front shoulder too early, striding across the body, and rushing the delivery are the most common mechanical issues. Film your pitcher from multiple angles to identify problems.
