I had the almost exact thing happen last summer... (I didn't call it either.)
DC comes out and calls the OC bush and a few other words
that I couldn't quite hear as DC had third base dugout. OC didn't do it again.
I talked with the UIC of the tourney and a few umpires about it and although we'd all love to call it INT and seatbelt a bush playing coach like this. We cant/shouldnt and it was explained like this to me.
"Players should know there own teams/coaches voices."
This was a ASA rule based tournament.
