My son was on a completely different mat. He got screwed out of a pin where he had the kid in the grapevine stuck for at least ten seconds. This occurred in the third period. The pin was not called and he lost. I did explain that it sucked it wasn't called. However, if my son hadn't allowed the other wrestler to stay on top the entire first two periods, he would have had enough points and the pin wouldn't have mattered. My son did understand this. I get upset with the ref's all the time. But, I do not allow that for an excuse nor question the ref. Their job is hard enough.
