Results are shown exactly as the source records them, ties included; several early series ended level and the champion column names the club the source credits. Club names are era-accurate: the 2001 clubs carry the names they used that season, and a franchise that plays today under a different name links to that modern franchise page, which owns the identity note. Round labels are our renderings of the source’s round codes; the digit on a Division Series or Wild Card code distinguishes the two concurrent pairings, not a seeding.
