Younger than middle school with rec. At that age if kids are being demolished then the issue is the league not doing a better job of balancing teams.
But agreed once the score got out of hand, not matter the situation you call off the hounds.
In scenario 1...if your kid is playing competitively and ur coaches are idiots to that level it sounds like you have bigger issues. I really hope you're not paying for this league? Unfortunately competitive baseball has become so common place now days anyone will say they'll run a team even without any level of coaching.
