“Recent changes in pitch types, counts, or other alterations in training should be carefully noted. For example, fastballs and change-up pitches result in less medial elbow stress than curveballs and sliders. Curveballs thrown at a young age, regardless of prior pitching experience, are associated with an increased risk of little league elbow and more serious injuries such as medial epicondylar avulsion fractures due to shear forces over a immature growth plate.”
