We had the same situation earlier in another tournament, where the ref called my son pinned on a roll through, and the ref was standing over the boys. No effort was made to get down to see the shoulders, he just called it that quickly. I made a point to speak to the ref, but was told it was a pin. This was in an open side of a novice/open tournament. I clearly know this rule and really would have made more of a fuss, but it would not have changed the match much overall and I don't like to see coaches get into the ref., although in a case where you are right...
