Not to sound like the poor sport American, but what the heck is up with the format in softball?
First, the US dominates every team in pool play, earning the number one seed. For some reason, they play the number 2 seed (Japan) in bracket play. They beat them again. The 3 and 4 seeds play against each other in order to face Japan. Then, Japan gets another shot at the US.
Just looking at that, it sounds like your normal double elimination tournament. You would think the format would require Japan to beat the US twice to win gold. Oh well, what can you do.
