Major League Baseball's regular season wraps up this week, and there are still a handful of spot to fill in the 2023 MLB playoff bracket. The Phillies and Rangers could clinch berths in the 12-team postseason field on Tuesday night, and the Brewers' magic number to secure the NL Central title is down to one. Entering Tuesday night, six teams have clinched playoff spots: the Braves, Dodgers, Orioles, Rays, Twins and Brewers.

You can find the full MLB playoff picture, along with divisional and wild-card standings here. The Phillies and Rangers appear likely to join the playoff field soon, and that will leave three American League teams (the Blue Jays, Astros and Mariners) fighting for two playoff spots and four National League teams (the Diamondbacks, Cubs, Marlins and Reds) fighting for two playoff spots in the regular season's final days. 

The 2023 MLB regular season wraps up Sunday (Oct. 1) and the postseason starts with the Wild Card Series in exactly one week (Oct. 3). This is the second year of MLB's 12-team playoff format. The top two division winners in both leagues get byes to the LDS round, while the other eight teams will square off in best-of-three Wild Card Series next week.
