2006 World Baseball Classic

The South Korean team playing in the 2006 World Baseball Classic included not just South Korean players based in South Korea, but South Korean players in the U.S. from Major League Baseball.

However, at the semifinals, the South Korean team lost to Japan, whom they had beaten twice previously. This led to controversy over the regulations of the WBC concerning the fact that South Korea had to face Japan three times and that it was Japan that was allowed to go to the finals, when it had four victories and three losses up to that point, two of those losses to South Korea, while the South Korean team, which had only one loss and had already beaten Japan twice, was eliminated from the finals.
