There are two videos on YouTube for this same wrestler. The first the pin is easy to see, the second is not as good for the camera angle. Its not a lousy call, but I understand the wrestler's complaint. The "pinned" wrestler seems to be laying on top of his opponent in such a fashion that it is hard to imagine that he was pinned. The thread linked above for this site has a good discussion and a diagram. And as evidenced by this new thread, it is a recurring misconception that the shoulders must be down to call a fall. The pinning area is defined as both shoulders or both scapula. The photo is #5 on page 60 of this year's rule book. The pinning area extends to the bottom of the cut-out on an ordinary singlet. That is what the official in the video was showing the wrestler after the match, if you watch the official he is describing the area between the top of shoulders to the bottom of the scapula. In this position, it is usually very easy to see those sharp-pointed scapula bones sticking out and touching the mat. Yes, the shoulders are way off the mat, but its still a pin. Commonly occurs in a cradle-situation. Fans, and some coaches, will object, because they are looking at the shoulders or they don't realize the pinning area extends nearly to the middle of the back.
