I think an important concept for pitchers, aside from various exercise strategies, is to limit the number of pitches thrown as much as possible. It is important to work with the players coaches as well. Even in the pros pitchers are throwing way too many pitches still. Managers have a conflict rationally when a pitcher is doing well, to pull them from a game. And even in the case of a pitcher not doing well, managers and pitchers alike are reluctant to pull a pitcher from a game or accept being pulled. The ego thing is dangerous. Pitchers want to pitch. But the repetitious nature of pitching is the base cause of pitching injuries. Youth baseball is all over this now.
