MLB Standings Explained
How divisions, wild card races, playoff seeding, and magic numbers work in Major League Baseball.
MLB standings can seem complicated at first — six divisions, two leagues, wild card races, magic numbers, and a 12-team playoff field all happening simultaneously over a 162-game regular season. This guide breaks down everything clearly, from how the division standings are calculated to how playoff seeding is determined.
The basic concept is straightforward: teams play 162 games, the best teams in each division and the best non-division winners (wild cards) advance to the postseason. But the mechanics of how that all works — particularly the 2022 expanded playoff format — are worth understanding fully to follow the pennant race.

What is a Magic Number?
A magic number is one of baseball's most useful tracking tools during the pennant race. It tells you exactly how close a leading team is to clinching the division or a playoff spot. The magic number represents the combined wins by the leading team and losses by the closest pursuer needed to mathematically eliminate that pursuer.
For example, if a team's magic number is 7, any combination of their wins and the closest competitor's losses that add up to 7 clinches the title. If they win 4 games while the competitor loses 3, they clinch (4+3=7).
Teams also track magic numbers for wild card clinching separately from division clinching, especially as September approaches and the playoff picture tightens.
