KBO League

Since the 2015 season, each team plays 144 games in the regular season, an increase from 128 games, along with the introduction of the KT Wiz to the league. Each team plays every other team 16 times.Korea Baseball Organization (2015). [http://www.koreabaseball.com/About/Change2015.aspx 2015 달라지는 점] {{webarchive|url=https://web.archive.org/web/20150405133123/http://www.koreabaseball.com/About/Change2015.aspx |date=2015-04-05 }} (Korean). Accessed on April 14, 2015. In general, Korean teams play six games a week, with every Monday off.

In mid-July of every season, the best players participate in the KBO All-Star Game. The franchises participating are divided into two sets of teams: "Dream All-Stars" (Doosan, KT, Lotte, Samsung, and SSG) and "Nanum All-Stars" (Kia, Hanwha, LG, NC and Kiwoom).

The KBO League's season culminates in its championship series, known as the KBO Korean Series. Currently, the top five teams qualify for the post-season based on win–loss records. The lowest-qualifying teams face off in a step-ladder playoff system, where each winner then faces the next-highest team, culminating in the Korean Series against the top-ranked team.

• KBO Wild Card Game: fifth-place team vs. fourth-place team

::Fourth-place team starts the series with a 1–0 lead and advances with one win or a tie, while the fifth-place team must win twice to advance.

• KBO Semi-playoffs: KBO Wild Card Game winner vs. third-place team

::Best of five series.

• KBO Playoffs: KBO Semi-playoffs winner vs. second-place team

::Best of five series.

• KBO Korean Series: KBO Playoffs winner vs. first-place team

::Best of seven series.

Any playoff games ending in an official tie are replayed, thereby raising the possibility of a close series containing more than the scheduled five or seven games.

The KBO League rules are essentially those of the 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.Kim Jae-Won (2009-01-13).

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.Kim, Jinsung. [https://apm.iar.ubc.ca/politics-in-professional-baseball-league-southkorea/ "More than Sports: Politics in the Origins of the Professional Baseball League in South Korea,"] Asia Pacific Memo (April 5, 2017).

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.{{Cite web |date=2021-03-04 |title=한국 프로야구 원년 우승 감독 김영덕, "OB 우승은 기적이었다" |url=https://www.chosun.com/sports/sports_photo/2021/03/04/IZENVUW5X46TRSNP4SG4LL3EVQ/ |access-date=2025-05-03 |website=The Chosun Ilbo|language=ko}}

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.Young Hoon Lee, Rodney Fort, editors. The Sports Business in The Pacific Rim: Economics and Policy (Springer, October 31, 2014) [https://books.google.com/books?id=9gYjBQAAQBAJ&dq=KBO+pennant+winners+1985&pg=PA178 p. 178]. 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.Kim Tae-jong. [https://www.koreatimes.co.kr/www/sports/2019/05/600_159816.html "No-hitter records in KBO history,"] The Korea Times (2014-06-25).

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 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 shrank 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.

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. But probably the most notable hitters to emerge from the 1990s were the Lions' Lee Seung-yuop and Yang Joon-hyuk, who between them now hold most of the KBO's career offensive records.

In 1990, MBC Chungyong became the LG Twins and an eighth franchise was added, the Ssangbangwool Raiders, who represented the North Jeolla Province region.

From 1991 to 1998, the season increased to 126 games. 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.Costello, Rory. [https://sabr.org/bioproj/person/5befc1b1 Dae-Sung Koo entry], Society for American Baseball Research website. Footnote 11: "For the 1999 and 2000 seasons, Korea operated two leagues, the Dream League and Magic League. Hanwha was in the Magic League." Retrieved May 18, 2020.[http://www.donga.com/en/article/all/20071017/255447/1/A-Miraculous-Comeback-in-the-Making "A Miraculous Comeback in the Making?"], The Dong-a Ilbo (October. 17, 2007). 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 the Hanwha Eagles, the LG Twins, the Samsung Lions, and the Ssangbangwool Raiders. That year the Eagles — in their 14th season — won their franchise's first (and only) Korean Series championship, after 14 years in the KBO.

Bigger changes were made in 2000 when the Hyundai Unicorns moved from Incheon to Suwon, and a new franchise, the SK Wyverns, took their place in Incheon. The Ssangbangwool Raiders became defunct. The league's two-division structure slightly shifted as well, with SK taking Ssangbangwool's place in the Magic Division, and Lotte and Samsung switching divisions.Zang, Hwansoo.{{cite web |url=http://www.donga.com/en/article/all/20000710/191483/1/Law-of-Jungle-Also-Exists-in-Pro-Baseball |title=Law of Jungle Also Exists in Pro Baseball |work=The Dong-a Ilbo |date=July 10, 2000}} Thus, the 2000 Dream League was composed of Doosan, Haitai, Hyundai, and Samsung; while the 2000 Magic League was composed of Hanwha, LG, Lotte, and SK.

Parity ruled the 2000s, with the Unicorns and Lions each winning three titles, and the upstart Wyverns winning two. The hard-luck Doosan Bears appeared in the Korean Series five times in the decade but only won it once, in 2001. Stars who emerged in the 2000s include all-time KBO hit king Park Yong-taik, the Giants' first-baseman Dae-ho Lee, and the Eagles' first-baseman Kim Tae-kyun. Other notable players from the era include slugging third-basemen Lee Bum-ho and Choi Jeong, the Bears' designated hitter Hong Sung-heon, and the Twins' long-time outfielder Lee Byung-kyu.

In 2001, the KBO returned to a single-division format. The Haitai Tigers became the Kia Tigers. From 2000 to 2012, the length of the regular season fluctuated between 126 and 133 games.

Despite its string of championships in the early 2000s, the Hyundai Unicorns franchise was disbanded in 2008. It was re-founded as the Woori Heroes and moved to Mok-dong in Seoul. In 2010, the team's naming rights were sold to Nexen Tire and the team was renamed the Nexen Heroes until the end of the 2018 season, when its naming rights were sold to Kiwoom Securities.

The Samsung Lions were a powerful team in the 2010s, winning the championship four times during six straight appearances in the Korean Series (from 2010 to 2015). The Doosan Bears were also a powerhouse, appearing in the Korean Series six times in the decade (including five straight appearances from 2015 to 2019), winning it three times.

Expansion resumed in the 2010s, with the addition of the NC Dinos, located in Changwon, which joined the league in 2013. It is the first team located in Changwon, the city having previously been the second home of the nearby Lotte Giants. The KBO played 128-game seasons in 2013–2014.

In 2015, the KT Wiz became the league's tenth franchise. They play their home games in Suwon, which had not had a team since the Hyundai Unicorns' disbandment. Since 2015 the KBO has played a 144-game season each year, and has added a fifth team to the playoffs, with the introduction of the Wild Card game. In 2015 the league also increased the active roster size of each team, from 26 to 27 (of those, 25 may play in any one game).[https://en.yna.co.kr/view/AEN20150324001400315 "Wild-card game, speed-up rules among changes for 2015 KBO season,"] Yonhap News Agency (March 24, 2015).

After a number of seasons of inflated offensive production, the KBO introduced a new "dejuiced" baseball before the 2019 season. The results showed in a significant decrease in runs per game and home runs per game.Kim, Sung Min. [https://blogs.fangraphs.com/lets-check-in-on-the-kbos-de-juiced-baseballs/ "Let’s Check in on the KBO’s De-Juiced Baseballs,"] FanGraphs (August 16, 2019).

The 2020 season was delayed by the COVID-19 pandemic, but finally started play in May 2020, with no fans in attendance. In response to the lack of live sports programming due to the pandemic, ESPN and the KBO League entered into an agreement to broadcast six games weekly for the 2020 season. The Opening Day game between the NC Dinos and Samsung Lions was broadcast as the first game under the agreement that night. Karl Ravech, Jason Benetti, Boog Sciambi, Eduardo Perez, and Jessica Mendoza, along with various guests, broadcast the game remotely via Internet from their homes.{{cite web |last1=ESPN News Services |title=ESPN to televise Korea Baseball Organization games |url=https://www.espn.com/mlb/story/_/id/29132165/espn-televise-korea-baseball-organization-games |website=ESPN.com |date=4 May 2020 |access-date=6 May 2020}} The deal was for the 2020 season only and was not renewed for 2021.{{Cite web |last=Kim |first=Daniel |date=5 March 2021 |title=As it was mentioned on air during yesterday's game, #KBOonESPN will not happen this season.

As with Nippon Professional Baseball (NPB), the KBO league places a cap on the number of foreign players allowed on club rosters. The foreign player limit is set at three (no more than two of them being pitchers),Reuter, Joel. [https://bleacherreport.com/articles/2890026-kbo-for-dummies-an-mlb-fans-guide-to-the-korean-baseball-league "KBO for Dummies: An MLB Fan's Guide to the Korean Baseball League,"] Bleacher Report (May 5, 2020). increased from two players from 2014. Foreign players can only sign single-season contracts, and they are restricted by a salary cap. Since 2019, the total compensation for a foreign player has been capped at $1 million.{{Cite web|url=http://koreajoongangdaily.joins.com/news/article/article.aspx?aid=3057480|title=KBO's final foreign player signed|website=Korea JoongAng Daily|date=28 December 2018 |access-date=2019-12-23}}{{Cite web|url=https://www.mlbtraderumors.com/2018/09/kbo-establishes-salary-ceiling-on-foreign-players.html|title=KBO Establishes Salary Ceiling On Foreign Players|website=MLB Trade Rumors|language=en-US|access-date=2019-12-23}} The foreign hitters on each team are expected to provide power in the middle of the order, while the foreign pitchers are expected to anchor the starting rotation. As with foreign players in the NPB, many of the most celebrated foreign players came to Korea after not finding success in the Major Leagues.

The KBO first began allowing foreign players in 1998,Lee, Seung Chan. [https://tht.fangraphs.com/foreign-players-in-the-kbo-what-the-future-holds/ "Foreign Players in the KBO: What the Future Holds,"] The Hardball Times (January 15, 2020). when each team was allowed to sign up to two imports. Traditionally, teams chose one hitter and one pitcher, although there were exceptions. (In 2001 and 2002, KBO teams were allowed three foreign-born players, but only two of them could be on the field at the same time.) By 2012, teams were using all their foreign-player allotments on pitchers, and there were no more foreign hitters in the KBO. After this happened again in 2013, the following season the KBO League raised the foreign-player limit to three for each team, but mandated that at least one foreign player had to be a hitter (again, with only two such players on the field at a time).[https://en.yna.co.kr/view/AEN20131216003151315 "KBO clubs snatch up new foreign players following rule change,"] Yonhap News Agency (December 16, 2013).

American Tyrone Woods was the first notable import. Debuting with the Doosan Bears in 1998, Woods was the first foreign player to hit a home run (as well as the first to be ejected from a game by an umpire).{{Cite web |date=2020-08-31 |title=[스잘알]우즈·니퍼트·테임즈…KBO 평정한 외국인 선수는? |url=https://www.newsis.com/view/NISX20200826_0001143341 |access-date=2025-05-03 |website=Newsis|language=ko}} In his first year Woods set a then-KBO record with 42 homers and won the MVP award (becoming the first foreign player to win the award).{{Cite web |date=2020-08-15 |title=[98프로야구] 우즈 첫 외국인선수 MVP |url=https://www.chosun.com/site/data/html_dir/1998/10/08/1998100870298.html |access-date=2025-05-03 |website=The Chosun Ilbo|language=ko}} In five years in Korea, Woods hit 174 homers, drove in 510 runs, and batted .294. (He later found additional success in Nippon Professional Baseball.) Woods left Korea with the longest career of any foreign player in KBO history, a record later eclipsed by hitter Jay Davis and pitcher Dustin Nippert. Davis played seven seasons for Hanwha (1999–2002, 2004–2006), compiling a .313 batting average, 167 home runs, and 591 RBI during that span.[https://www.baseball-reference.com/register/player.fcgi?id=davis-008ger "Jay Davis,"] Baseball-Reference.com. Retrieved May 21, 2020.

Foreign pitchers with extended careers in the KBO include Dustin Nippert, who compiled a win–loss record of 102–51 and 1,082 strikeouts in eight seasons (a foreign player record); and Danny Rios, who in six seasons was 90–59 with 807 strikeouts and an ERA of 3.01, which is the lowest career ERA of any foreign pitcher in the KBO. Josh Lindblom pitched in the KBO for five seasons, compiling a 63–34 record and 750 strikeouts. Rios was given the 2008 KBO League Most Valuable Player Award, Nippert was KBO MVP in 2016, and Lindblom won the award in 2019.

American Jerry Royster was the first-ever non-Korean to take the helm of one of South Korea's professional baseball clubs when he was signed as manager of the Lotte Giants in 2007.{{cite news

{{main|List of Major League Baseball players from South Korea}}

Several KBO players have had successful careers in Japan's Nippon Professional Baseball (NPB). Baek In-chun played professionally in Japan from 1963 to 1981, compiling 209 home runs, 776 RBI, and 1,831 hits in the NPB. (He returned to Korea for his final three seasons as a player.) Lee Seung-yuop, who holds the KBO records for career home runs, runs scored, RBIs, total bases, slugging percentage and OPS, also played eight seasons in the NPB, accumulating an additional 159 home runs and 439 RBI. Other KBO hitters who had some success in the NPB include Kim Tae-kyun and Dae-ho Lee. Korean pitchers who have had an impact in the NPB include Sun Dong-yol, Lim Chang-yong, and Seung-hwan Oh (who led the NPB in saves in both 2014 and 2015).

Several Korean players have also successfully transitioned from the KBO to American Major League Baseball, starting in 1994 with pitcher Chan Ho Park. Prior to Park, the South Korea-born Mexican pitcher Ernesto Carlos was signed to an American minor league contract with the San Francisco Giants' organization in 1968 after having found success in the NPB.{{Cite web |date=2015-01-23 |title=[주말기획] 한국인 14명 '꿈의 무대'…강정호 15번째 예약하다 |url=https://sports.donga.com/sports/article/all/20150122/69236227/3 |access-date=2025-05-03 |website=sports.donga.com|language=ko}} Similarly, pitcher Park Chul-soon signed a minor league deal with the Milwaukee Brewers organization in 1980.{{Cite web |date=2025-03-17 |title=[KBO 호프]22연승 신화의 원년 최고 스타 박철순, 한국야구로 엇갈린 야구 인생 |url=https://www.chosun.com/sports/baseball/2025/03/18/RUF5HH3HO6JKHCQCBM4ORVSN2Y/ |access-date=2025-05-03 |website=The Chosun Ilbo|language=ko}} Neither Ernesto Carlos nor Park Chul-soon, however, made it to the Major Leagues. Other Korean players who have had lengthy MLB careers include outfielder Shin-Soo Choo and pitcher Byung-hyun Kim. In 2013, Hanwha Eagles ace Hyun-jin Ryu became the first player from the KBO to join an MLB team through the posting system.
