According to every sports medicine professional every pitcher in MLB is at risk of arm injury because the act of throwing a baseball is an unnatural act, it's well documented, if you put the effort in you can find results from orthopedic surgeons as well as motion therapists that deal with pitcher recovery.
Pitchers get hurt because they don't throw enough.
