I know a girl at my school who's on the varsity team and she's pretty much the only girl who pitches. Every time I go watch them she pitches a whole game by herself and doesn't seem fatigued at all. This surprised me, because in baseball a team can't have one guy who does all the pitching for every time since it causes stress on their arm. Do softball pitchers get sore arms, torn rotator cuffs, or a elbow injury like Tommy John? This may seem like a stupid question but just curious.
