Baseball in South Korea

Baseball is believed to have been introduced to Korea in 1905 by American missionaries during the Korean Empire, after which it gradually attained prominence. It is one of the most popular sports in the country. There are 10 pro teams in the Korea Baseball Organization. Baseball season runs from March to October.

On December 1921, a team of American Major League players stopped in Seoul during a tour of Asia, and a Korean team was assembled to play against them. The Koreans were defeated, 23-3. Various Korean cities also participated in the Japanese Intercity Baseball Tournament, from its inception in 1927 until 1942. In 1940 and 1942 Seoul won the tournament, defeating (respectively) the teams of Dalian and Osaka.

The 1980s marked the beginning of the era of professional baseball in Korea. In 1982 the MBC Chungyong, Lotte Giants, Samsung Lions, OB Bears, Haitai Tigers, and Sammi Superstars were launched, as was the highest-level league that they composed, the Korea Baseball Championship. This league continues to be Korea's major league, although as of 2015 it has expanded to 10 teams.

The sport reached a new level of popularity when pitcher Chan Ho Park made his debut for the Los Angeles Dodgers in 1994. Park achieved a great deal of success in his Major League Baseball career, and paved the way for the American success of fellow Korean players such as Hee-seop Choi, Byung Hyun Kim, Jung Bong, Shin-Soo Choo, Hyun-Jin Ryu, and Jung-ho Kang.
