MLB Playoff Format Explained: Wild Cards to World Series
A concise guide to the current MLB postseason structure, including wild-card rounds, division series, league championship series, and the World Series.
The October ladder
MLB’s postseason rewards division winners and the best non-division winners via wild cards. Early rounds are short and volatile; later rounds expand and usually give stronger teams more room to let rotation depth matter.
Seeding still starts with the regular-season record. That is why July and August standings races are not just theater—they set the bracket math.
