The final week of the 2023 Major League Baseball season is here, and more than half of the 12-team postseason field is set. The reigning National League champion Phillies became the latest team to clinch a playoff berth as they locked up the NL's No. 4 seed on Tuesday night. The Brewers also clinched the NL Central thanks a brutal Cubs loss, and now the AL East and AL West are the only divisions still up for grabs.

There are eight teams fighting for the final five playoff spots. The Rangers control their own destiny in the AL West, while the Astros and Mariners are trying to either catch Texas or secure a wild-card spot. The Blue Jays are three wins away from locking up an AL wild-card spot.

In the NL, all the divisions are accounted for and just the final two wild-card spots are up in the air. The Diamondbacks have the edge on the No. 5 seed, while the Cubs, Marlins and Reds are all still in the mix.

The 2023 MLB playoff picture is also notable for who is not in it. The Padres, Yankees, Mets and Cardinals -- all playoff teams in 2022 and expected contenders in 2023 -- have had disappointing years that will likely end with the regular season. The Angels saw their playoff hopes dashed in a dismal August. The Halos crashed out of the race in August and finally shut Shohei Ohtani for the season.

As a reminder, MLB now uses a 12-team playoff format with the three division winners and three wild card teams in both leagues qualifying for the postseason. The two division winners with the best records in each league get byes to the League Division Series round, while the other eight teams square off in a best-of-three Wild Card Series.
