MLB playoff picture all set, best-of-3 matchups start Friday
The postseason, expanded from 10 teams last year to 12 this season, begins Friday with a newly created wild-card round. All four series are best two of three — three days in a row, no breaks, with the higher seed hosting every game. In the National League, it's Padres-Mets and Phillies-Cardinals. In the American League, it's Mariners-Blue Jays and Rays-Guardians.
