Youth Baseball Arm Care: Protecting Young Pitchers
Youth Baseball Arm Care: Protecting Young Pitchers
Elbow and shoulder injuries in young pitchers have surged. A guide to pitch counts, rest and arm care — what every baseball parent should know.
Arm injuries in young pitchers have risen alarmingly — Tommy John surgery in youth has multiplied over two decades. The cause is clear and the fixes are simple: manage workload and rest. Here is a practical guide to protecting young arms.
1. The overuse problem
Too many pitches, too often.
Overuse is the number-one cause of youth pitching injuries. Research links throwing more than ~80 pitches per game to roughly four times the injury risk, and pitching competitively more than 8 months a year to about five times the risk of needing surgery.1
2. Pitch counts & rest
Limits exist for a reason.
Programs like MLB/USA Baseball’s Pitch Smart set age-based daily pitch limits and required rest days (for example, a 10-year-old’s daily max is around 75 pitches).1 Respecting these limits is the simplest protection.
3. Key habits
Beyond the count.
Avoid pitching in multiple leagues at once, avoid pitching and catching on the same team, take months off from throwing each year, and don’t pitch through fatigue. General injury prevention and recovery habits apply too.
4. The warning signs
Pain is never normal.
Arm pain, reduced velocity or control, or reluctance to throw should be taken seriously — rest and seek professional assessment. When in doubt, stop and consult a medical professional.
