Everyone makes mistakes in BB. The trick is what you do with your next play, or outing. My 15yo has always been a top pitcher. It always came easy to him- excellent control and composure. Fielding was his weakness. This year he has turned himself into a "+" OF'er, to his delight. That long lanky frame is tracking down balls and breaking batter's hearts.
But can he throw a strike? Nooooooo...!
I blame puberty for everything.
