Every 2003 MLB playoff series, three ways: the season race carried on into the postseason, who beat their seeding, and the bracket.
Loading playoff data…
The same race these clubs ran all season, carried on through the postseason on one scale and on real dates.
Where each club finished the season against how far it went, ranked on record rather than seed.
Who played whom, round by round, which no line chart can say.

The left column ranks this field by regular season record, not by seed number: seeding rules differ by era, so this site uses records everywhere instead. The right column groups clubs by the round they went out in, which is not the same as the number of rounds they won, because a bye carries a club further without it winning anything. The figure beside a name is places moved between the two columns, and part of it is only where a club sat inside its band. Nothing here is a prediction. The data notes carry the whole method.
