excessive defensive contact of baserunner

[aflacduck31]

Hi all - new to the forum.

I coach an 8u team that is coach pitch. We played our first game Saturday and a play occurred that I was curious about.

With 1 out and runners on 1st (r2) and 2nd (r1), batter (b1) hits a ball through the left side of the infield. R2 touches third and heads home on the play as the ball returns to the infield. The defensive third baseman retrieves the ball near the circle and runs down the runner attempting to score.

The defensive player applies the tag to the runner (before she reaches home plate) from behind to the runners left shoulder. The tag is applied with both arms bent in some semblance of a "praying" motion. Once the tag is applied, the fielder extends both arms, shoving the runner to the ground.

The umpire makes no immediate call, but calls the opposing coach to the field for a conference that does not include me. When he returns to the plate and indicates ready for play, he informs me that the out stands. The tagged baserunner has to be removed from the game due to her injuries.

So, after all of that, here's the question.......

I don't dispute that the tag resulted in an out. However, once the out was recorded, excessive force seemed to come into play. In a one-on-one conversation (not heated) after completion of the game, the umpire informs me that there is no ASA rule regarding defensive contact of this nature. Is he correct? Were there mistakes made on this play? Why would I have not been included in the conference?

As a side note, we did complete and win the game, so it's not an appelate situation.

Thoughts? Comments?
