Within each league, the division winners are the No. 1, No. 2, and No. 3 seeds, based on win–loss records. The team with the best record among non-division winners will be the first wildcard and the No. 4 seed. The team with the second-best record among non-division winners will be the second wildcard and the No. 5 seed. In the wildcard round, the No. 5 seed will play at the No. 4 seed in a one-game playoff. For the division series, the matchup will be the No. 1 seed against the Wild Card Game winner and the No. 2 seed against the No. 3 seed. Since 2017, home-field advantage in the World Series is determined by regular-season records of the two league champions, replacing a system used for the prior 14 seasons where the champion of the league that won the All-Star Game would receive home-field advantage.
