Too much, too early. Do you see anyone in the majors throwing that many pitches this early? I wonder why?
90 pitches over 4 innings averages out at 22.5 pitches per inning so it does seem that the pitcher was struggling. What was his highest pitch count for one inning? Extended pitch count innings fatigue the trowing arm and should shorten up a pitchers outing. Especially for a 15yr old pitcher. What was the coach trying to prove? Didn't he have anyone in the bullpen ready to go?
