the adoption of a playoff system, in which the top two teams from each half-season played for the right to get to the Korean Series. 1986 also saw the OB Bears moving from Daejeon to share Jamsil Baseball Stadium with MBC Chungyong in Seoul. A new franchise, the Binggrae Eagles, joined the league, replacing the vacancy in Daejeon made by OB's move, and expanding the league to seven teams. From 1986 to 1988, the regular season shrunk to a total of 108 games. 1988 saw the Cheongbo Pintos change ownership again, becoming the Pacific Dolphins. In 1989 the KBO eliminated the two half-season pennants, moving to a single season of 120 games. The 1990s In the 1990s the Tigers were again dominant, winning the championship four times in the decade — 1991, 1993, 1996, and 1997. The Tigers were led by hitting-machine Lee Jong-beom and slugger Lee Ho-joon. Other KBO players who starred in the 1990s were Eagles' pitcher Song Jin-woo, who eventually became the all-time KBO leader in wins, strikeouts, and innings pitched; slugging catcher Park Kyung-oan, the first catcher in KBO history to hit 300 home runs; and stolen base king Jeon Jun-ho.

The Lotte Giants won the Korean Series championship in 1992; the team has not won it since. There was little other change during this period except for a few major sponsors: in 1993 the Binggrae Eagles became the Hanwha Eagles, in 1996 the Pacific Dolphins became the Hyundai Unicorns, and in 1999 the OB Bears became the Doosan Bears. The 1998 Korean Series was won by the Hyundai Unicorns for the franchise's first championship in 16 years of existence. (The team would go on to win the championship in 2000, 2003, and 2004.) In 1999 the season was expanded to 132 games, and the KBO separated into two divisions — the Dream League and the Magic League. The 1999 Dream League consisted of the Doosan Bears, the Lotte Giants, the Haitai Tigers, and the Hyundai Unicorns; the 1999 Magic League consisted of
