HS Fed Rule 8, Section 2, Article 5, 8. Tag-Ups

[Al McCormick]

I have had this called against my team bothways, therefore I have two questions:

1. In both situations the runners left thinking the ball was in for a basehit and took off without any effort to Tag UP. Obviously with the realitive wording, "If a runner leaves a base too soon on a caught fly ball...." the question becomes: Does the runner have to show an effort of tagging up before the "time play" portion goes into effect, allowing a run to score even if it is the third out? The corollary, the fact he left at all implies he left too soon?

One up allowed the run to score, the other said it was the third out.

2. My second question, does this rule apply in NCAA rules as well as American League and National League.

Appreciate your support.
