Before diving into a breakdown of the playoff picture, here’s what’s at stake Sunday and what has happened so far:

The Red Sox beat the Detroit Tigers, clinching the AL Central title and a historic comeback for the Cleveland Guardians. With that result, the Guardians secure the No. 3 seed, the Red Sox get the No. 5, and the Tigers are the No. 6 in the American League.

The Toronto Blue Jays and New York Yankees are tied atop the AL East. The winner gets the No. 1 seed in the AL and a bye to the division series; the loser gets the top wild card and the No. 4 seed. The Jays hold the tiebreaker, so a win or Yankees loss Sunday clinches the division title for Toronto.

The New York Mets and Cincinnati Reds are tied for the final playoff spot in the NL. The Reds lost Sunday, but they hold the tiebreaker, so if the Mets lose, Cincinnati clinches the last postseason berth and the No. 6 seed.
