The final day of the 2026 MLB regular season is set for Sunday, after which the 12 qualifying teams will be honed in on preparations for the postseason. The playoffs will get underway quickly after the conclusion of the season, with the wild-card round set to begin just two days later, on Tuesday, Sept. 29.
The wild-card round consists of four series––two in the American League and two in the National League, each of which are played in a best-of-three format. The first team to win two games advances to the divisional round. The team with the better regular-season record will have home-field advantage throughout the entire round, with each game set to be played at that club’s home stadium.
