I can't remember getting angry at my kids for something that they did on the field. Exasperated but not mad.
In my experience the dads (almost always, it's the dads) that do get angry with their kids (and with other kids) are guys who haven't played the game much, or haven't played it well. I've heard about ex major leaguers going ballistic on their players, so I know there are exceptions.
I do get mad at other stuff unrelated to players but I refuse to talk about that until my 2022 completes his senior HS season.
I will share one example, though: It makes me stone-cold bonkers, ape-sh.t crazy, certifiably cuckoo when a starter is pinch hit for after their first at bat. It makes me even more nuts when the pinch hitter hits safely.
But that's just me.
