Coed slopitch and the plate line vs home plate

[SactoBlue]

Situation: Coed slo pitch rec, instead of having to touch home plate to score a run there is a line the runners cross that extends from home plate to backstop to score. Supposed to keep the typically unskilled catcher from getting run over by an overzealous runner on close plays at home....never a tag, always a force.

I had a close play at home and in my typical fashion I was moving to cover that play backing up in foul ground and backed into the runner trying to score from 3rd. I can't see him because I'm backing up. I recognize that with this situation I'm not in the right place to call this because instead of the runner being in front of me he's running in back of me ..... but training you know. IMHO had I not backed into the runners path he would have scored. We're talking only a one stride from crossing the line. Ball came to catcher who had foot on mat to get the force.

Needless to say, because I blocked the runner the ball got there 1st.

I ruled that the run scored because I backed into runner at last second .... my fault I'm thinking. Of course no matter the call I was going to hear it.

Anyone got any opinions on the ruling? There weren't any rules covering this obviously since it's a league rule. Was I "part of the field of play" in this situation, even though had I not moved there would have been no contact.

thanks.
