Upon reaching the semifinals, the South Korean government announced that it would waive for the players on the team the mandatory two-year military service required of all young South Korean men. 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.

South Korea won the final Pool A game by a 1–0 win over Japan in order to advance as the Pool A winner. In Pool 1, the round 2 of the WBC, South Korea beat Mexico 8–2 and then went on to beat Japan again 4–1, securing advancement to the semifinals. South Korea beat Venezuela 10–2 to secure a spot on the finals. In the final game however, South Korea lost to Japan 5–3.
Since the 2000 Summer Olympic Games in Sydney, professional baseball players have been permitted to play and the South Korean team that was formed was often called the "Korean Dream Team". This team won the bronze medal.. At that time, the top four teams (Cuba, United States, South Korea and Japan) advanced to the semi-finals. In the semi-final game, the South Koreans faced the United States team and lost. In the bronze medal match, the South Koreans played against the Japanese and won the game 3–1.
Going into the tournament rated by the experts as an outsider, or a dark horse at most, South Korea surprised everybody by finishing the group stage in first place with a perfect 7–0 record. The team began its run with come from behind win against heavily favored United States, scoring the winning run in the bottom of the 9th inning with a sacrifice fly. Disappointment soon followed the next game, however, as China (undeniably the weakest team in the tournament) stymied South Korea for most of the game before the game was suspended because of rain in the 6th inning with a 0–0 score. South Korea bounced back the following day with a tightly contested 1–0 victory over Canada, with Ryu Hyun-Jin recording a complete game shutout. After dispatching their rivals Japan 5–3 in the next game, South Korea finished off China in the continuation of the aforementioned suspended game by winning 1–0 in the extra innings. South Korea then clinched their place in the final four by beating Chinese Taipei 9–8, followed by another surprise victory over heavily favored Cubans, 7–4 (which guaranteed them finishing first place in the group round). The team finished their Round Robin Tournament in style, hammering the Netherlands 10–0 and beating them on mercy rule.
In the Semifinal match, the team was once again matched up against their arch-rivals Japan. The first half of the game was very tight as Japan was leading 2–1 going into the 7th inning. South Korea soon tied the ballgame at 2 apiece in the bottom half, then took the lead in the 8th thanks in large part to Lee Seung-Yeop's clutch 2-run home run. South Korea added 2 more runs that inning. South Korea eventually ended with a 6–2 victory. In the finals they overcame the perennial favorites Cuba for the second time in the tournament, surviving a bases-loaded 9th inning situation with a double play to win the game 3–2, allowing South Korea to obtain their gold medal for Baseball.
