While no injury can be completely prevented, proper mechanics, rest and strength can reduce the risk of injury. USA Baseball has developed guidelines for young pitchers to help reduce the risk of injury.
Recommended pitch counts by age and associated rest periods:
Age of Athlete
Pitch Limits per Day
Number of Pitches Thrown
Days of Rest

Parents need to also be aware of any reports of pain, fatigue or changes in throwing motions. These are often warning signs that, if ignored, may lead to more serious injury.
