Whatever, the most controversial topic is the judge who made successive misjudge not only in the game of "USA vs Japan" also in the game of "USA vs Mexico". I don't mean to mention of this person, the important thing is the rules of the management.
In World Cup Soccer, if there is a game Japan vs France, they not only choose the judges from both Japan and France, but they don't choose from both Asia and Europe.
If WBC aims to be the event that decide the no.1 national team, they should prepare the judges who are in top level fairly and justly.
Altough, in WBC, the judge from USA made judges which made advantage for USA team, then the judge kept judging after semi-final. If he were in the controversy, they should bring substitute.
