As for velocity, I also think lefties, more often than righties, specifically are trained to get left-handed hitters out vs righties who train more to get every hitter out. So this could explain a prioritization in movement and craftiness over pure power pitching.

I have a hunch that this percentage disparity theory ignores social aspects of parents and coaches pushing lefties to pitch plus it ignores that four entire positions are unavailable to lefties.
