series containing more than the scheduled five or seven games. Rules The KBO League rules are essentially those of the American Major League Baseball (MLB). The designated hitter rule is universal in KBO. Traditionally, South Korean professional baseball games have a maximum number of extra innings before a game is declared an official tie. The KBO abolished this limit for the 2008 season, but it was reinstated in 2009, with a 12-inning limit imposed during the regular season, and a 15-inning limit for playoff games. History Origins The first game was played on March 27, 1982, between the Samsung Lions and the MBC Chungyong at Dongdaemun Baseball Stadium, Seoul. Then-president Chun Doo-hwan threw out the ceremonial first pitch. The 1982 charter teams of its first season were: Haitai Tigers, based in Gwangju Lotte Giants, based in Busan MBC Chungyong, based in Seoul OB Bears, based in Daejeon Sammi Superstars, based in Incheon Samsung Lions, based in Daegu The first Korean Series featured the Bears versus the Lions, with OB winning the championship 4-games-to-1, with a tie. The 1980s The Haitai Tigers dominated the 1980s, winning the Korean Series five times — in 1983, 1986, and 1987 through 1989. They were led by pitcher Sun Dong-yol and infielders Kim Seong-han and Han Dae-hwa. Other KBO stars whose careers took off in the 1980s were sluggers Chang Jong-hoon and Lee Man-soo. From 1982 to 1988, the regular season was divided into two (a spring season and a fall season), with a first-half pennant winner and a latter-half pennant winner. The two pennant winners then played each other for the Korean Series championship. The 1982 campaign featured an 80-game (in total) season, which expanded to 100 games from 1983 to 1984. Rosters for each team were small (sometimes as few as 14 players), and many players in the league both pitched and batted. Bang Soo-won of the Haitai Tigers pitched the first no-hitter in Korean professional baseball history, in 1984 against the Sammi Superstars. Mid-season 1985, the Sammi Superstars were sold and became known as the Chungbo Pintos, and the full season expanded to 110 games. Because the Samsung Lions won both half-season pennants (with a still single-season record .706 winning percentage), the Lions won the title outright so no Korean Series was played that year. Because of the lack of a postseason in 1985, the next year saw some major changes, with
