It is on the umpires to eject players. The umpires have the full support of USSSA, Stro, the conf uic Slim, the national UiC Dave Maury, and the media (me).
If they don’t eject unsportsmanlike conduct when they see it then that is on the umpires and that includes during world tournaments.
Those of us in charge couldn’t care less who gets ejected. There is another major player or coach on the bench that will replace the ejected person so it won’t affect the outcome of the game at all.
Also there is a difference between arguing a call and a personal attack on an umpire.
