2021 KBO League season
sports season

The 2021 KBO League season, also known by naming rights sponsorship as 2021 Shinhan Bank SOL KBO League (Korean: 2021 신한은행 SOL KBO 리그), was the 40th season in the history of the KBO League.
At the conclusion of the regular season, all five playoff positions were undecided going into the final day of the schedule. The Samsung Lions and KT Wiz met in a tiebreaker game to decide the regular season champion, the first such game since 1985. The NC Dinos became the first defending champion to miss the playoffs since the Kia Tigers in 2010, while the Doosan Bears qualified for the seventh consecutive year. In the postseason, the Korean Series was won by KT Wiz, who defeated the Doosan Bears who had advanced the championship series as a wild card.
2021 also marked the first KBO season for the SSG Landers, formerly known as the SK Wyverns.
Season format
The KBO is a 10-team league. Each team plays 144 games, facing the other nine teams 16 times apiece. Games are declared ties after 12 innings (15 in the postseason), and those contests have no bearing on a team’s winning percentage. Five teams make the playoffs, where the league uses a step-ladder format; the fifth- and fourth-placed teams battle in a Wild Card round, the winner faces the three seed, and so on.
This brief starts where responsible research should: with the source description of “2021 KBO League season” as sports season. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as sports season. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 14, 2024. The linked authority identifier is Q106390526. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 1985 and 2010.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
