They are playing by WPA rules which states the Ten ball must be called! It was announced this way at the players meeting, which Shane failed to attend. I think the official and the TD made the right call here. If they had given Shane a break, then any player who didn't call the Ten would say Shane got a break, so why not me too? You CANNOT favor the top players when running a tournament. It's that simple. Shane KNOWS he is responsible for this and that's why he came back and played his match later.
