At present, only one American men's professional sports body — Major League Baseball — uses the best-of-five playoff, doing so in its second round, known as the Division Series. At one time, however, the League Championship Series was best-of-five, from its birth with both leagues' realignment into two divisions in , continuing until the round was lengthened to best-of-seven in . (This change would have immediate ramifications: In the American League, in each of the first two years where the LCS used the best-of-seven format, the Kansas City Royals in 1985 and the Boston Red Sox in 1986 fell behind 3–1, which previously would have eliminated them, before coming back to win the series.) When the wild card was first used in (it was created for the season, but that year's entire postseason was cancelled due to a players' strike), the best-of-five format was authorized for the new Division Series, in which eight teams participated.
