The 2026 MLB regular season is over, and the 12-team postseason bracket is set. The best-of-three wild-card series begin Tuesday, September 29, with the division series starting Saturday, October 3, according to USA Today.

The oddest story is the Houston Astros. They finished 81-81 and won the AL West over the Texas Rangers (80-82) on the final day. That is the worst full-season record ever for an MLB playoff team — yet as division champions, they host the Chicago White Sox in the wild-card round.

The Philadelphia Phillies clinched the final National League wild-card spot on the last day, completing the field.

AL seeds: No. 1 Tampa Bay Rays (98-64), No. 2 Cleveland Guardians (85-77), No. 3 Astros, No. 4 New York Yankees (93-68), No. 5 Boston Red Sox (87-75), No. 6 White Sox (84-78). NL seeds: No. 1 Milwaukee Brewers (100-plus wins), No. 2 Los Angeles Dodgers, No. 3 Atlanta Braves, No. 4 San Diego Padres (91-71), No. 5 Chicago Cubs (89-73), No. 6 Phillies (88-74).

Wild-card matchups: White Sox at Astros, Red Sox at Yankees, Phillies at Braves, Cubs at Padres. The Brewers carry baseball's best record into October, while Tampa Bay tops the AL.
