Top 20 Teams in World Baseball Classic History: 10 to 1
South Korea went 6-1 in the inaugural World Baseball Classic in 2006. Nobody predicted that.
Japan arrived with the star power. The Dominican Republic had the deepest lineup in the field. The United States had the household names. South Korea had a pitching staff nobody outside Seoul took seriously, and it didn’t matter.
Through Pool A, they held opponents to 3 runs across three games. That’s not variance. That’s a team that was simply better than what they faced, and they knew it.
Seung Youp Lee was the engine offensively, putting up a 1.372 OPS with 5 home runs and 10 RBI over the course of the tournament. Chan Ho Park worked mainly out of the bullpen and logged 10 innings of zero earned runs. Jae Weong Seo made 3 starts and gave up one run in 14 innings. In a compressed tournament format where starters rarely get stretched out, that kind of sustained efficiency doesn’t happen by accident.
The second round moved to Los Angeles, and South Korea didn’t slow down. They beat Mexico, then took down the United States 7-3, with Lee’s 5th home run of the tournament putting an exclamation on it. They even knocked Japan around in what was technically a low-stakes pool game, just to signal that the first meeting wasn’t a product of fortune.
It didn’t save them.
Mexico upset the United States to send Japan through to the semifinals on tiebreaker math. South Korea and Japan met for a third time, which at that point felt like the tournament’s real final.
Koji Uehara and Seo traded zeros through five innings, the kind of pitching duel that short tournaments rarely produce. “That was as good as it gets in international ball,” one scout told reporters covering the semifinal. Then the seventh inning arrived. Kosuke Fukudome and Hitoshi Tamura both went deep in a five-run frame that blew the game open. South Korea’s bullpen couldn’t stop it, and they didn’t score enough afterward to make it close.
A 6-1 record and a semifinal exit in the first WBC history looks like a failure only if you came in expecting them to win it all, which almost no one did. The 2006 run established South Korea as a program that could compete at the top of international baseball, not just show up and make noise. Two years later they were in the finals.
Just Baseball ranked this squad 10th all-time in WBC team history, and that’s a reasonable landing spot. It’s a higher bar than it sounds when you consider the company. The competition includes Japan’s back-to-back championship rosters and teams stacked with MLB All-Star talent across multiple eras.
South Korea’s 2006 roster won’t show up on a lot of lists when people talk about the tournament’s iconic teams. Chan Ho Park’s scoreless innings and Seo’s 14-inning workload deserve more credit than they get. That group did something genuinely rare: they changed how the baseball world thought about a country’s program, and the results backed it up completely.
