The entire conversation I had with him could pretty much be boiled down to me saying "Is it my imagination or do you throw harder in your pitching lessons?" His response was "No, it's not your imagination *insert catcher name* already has to tape his wrist and thumb to catch me, he's only 85 pounds, the last time I threw really hard at him it knocked him over and the ball hurt his hand so bad he couldn't catch for a week, since then I just throw about 75%, it's no big deal, it's easier to control the pitches when I throw slower anyway."
CaCO3,
you've made reference to this sort of things multiple times (including hit batted balls hurting fielders). Perhaps he should be playing at a higher level with better ball players. You won't see this a majors level for his age group.
