Major League Baseball's postseason is just a week away, and the field is starting to take shape.

But there's still plenty to determine before the regular season comes to a close on Sunday, Sept. 28. Seeding in both leagues could come down to the final day, and bids for the final wild-card spots have become increasingly tight. In the American League, one of the Boston Red Sox, Cleveland Guardians, Detroit Tigers and Houston Astros will be left on the outside looking in. And in the National League, the race for the final playoff spot is on between the New York Mets, Cincinnati Reds and Arizona Diamondbacks.

Here is every MLB team that has clinched a postseason berth, along with the magic numbers for teams to lock up a spot:
