The KBO refers to the Korea Baseball Organization, which operates professional baseball in South Korea, and its subordinate professional league. The KBO League currently consists of 10 clubs, and each team competes during the regular season to determine their ranking. After the regular season, the top teams advance to the postseason, eventually determining the champion in the Korean Series. The KBO features players in various positions, including pitchers, catchers, infielders, and outfielders, and each team operates under the direction of a manager and coaching staff. In addition to domestic players, foreign players also join teams to compete. Players compete by accumulating various individual records such as batting average, home runs, RBIs, hits, ERA, strikeouts, wins, and saves. Professional baseball players are nominated and join clubs through the rookie draft, and then grow by competing in the Futures League and the first-team roster. Outstanding players are selected for the national team to compete in international tournaments. The KBO plays a central role in Korean baseball, managing overall professional baseball operations, including game management, league regulations, player registration, rookie drafts, and umpire operations.
