cause you can't argue against a judgement.
here's one that i argued and got overturned.
men on 1st and 3rd, 1 out. batter hits a ball to right field and the runner takes off from first. when he realizes the ball has been caught he heads back to 1st base but the 1st baseman already has the ball so he stops and they look at each other for a few seconds and then the 1st baseman turns around and just touches the base for the 3rd out.
the ump wouldn't count the run because he called it a "force out" at first.
