Third strike offense?

[MD Longhorn]

You did not. In fact, I believe you erred once you began calling OUT more than once or trying to be louder, influencing the play. You are the official. Make the calls. Don't affect the game. And definitely don't invent rules to instill your personal sense of fairness.

Absolutely cannot believe this worked more than once. If the coach can't get his catcher to not throw when she's caught the ball, it's not your problem to fix.

And please don't treat 12U like lower-level ball. At 12U, they should know the game.

You didn't mention the rule set being used, but most specifically say that a batter running on the third strike, when not entitled to, is not a rule violation. The ASA rule is 8-7-P.

Also, to call interference you generally need a player interfere with a legitimate play. How did a throw to first to "retire" an already retired player interfere with a play against an active runner? There was no out to be had at first base, so there no play to be nothing to be interfered with at first base.

As an official you did your job (well, up until you called interference on a play where it shouldn't have been). You called the strike and called the batter out when she started to run. The rest is on the defense. It's an old line, but it bears repeating: The defense is responsible for knowing the situation and playing it accordingly. If they make unnecessary throws over and over again, that is something that their coaches should be addressing, not the umpire.
