Baseball Pitch Count Rules (2026)

By Emma Wilson · October 10, 2026

Why Pitch Counts Matter

Overuse is the number one cause of arm injuries in youth baseball. Research consistently shows that pitchers who exceed recommended pitch counts are significantly more likely to develop elbow and shoulder injuries, including UCL tears requiring Tommy John surgery.

Age-Based Daily Limits

USA Baseball's Pitch Smart guidelines set these daily maximums: Ages 7-8: 50 pitches. Ages 9-10: 75 pitches. Ages 11-12: 85 pitches. Ages 13-16: 95 pitches. Ages 17-18: 105 pitches.

Required Rest Days

The number of pitches thrown determines mandatory rest. For ages 15-18: 1-30 pitches = 0 days rest, 31-45 = 1 day, 46-60 = 2 days, 61-75 = 3 days, 76+ = 4 days. Younger age groups require more rest at each threshold.

Warning Signs

Remove a pitcher immediately if they show: decreased velocity, change in arm slot, grimacing while throwing, rubbing the elbow or shoulder, or loss of control. These are your body's way of saying the muscles and ligaments are fatigued.

Yearly Limits

Pitchers should take at least 4 months off from throwing each year. Total yearly innings should not exceed 100 for ages 14 and under, and 150 for high school players. Multi-sport participation naturally provides this rest.

Position Changes

A pitcher removed from the mound should not move to catcher, as the throwing demands are similar. They can play other positions that don't require frequent high-intensity throws.
