With three days left in the 2026 MLB regular season, multiple playoff races remain undecided, including two division titles. The Chicago White Sox and Chicago Cubs both clinched playoff berths on Thursday, marking the first time both Chicago clubs secured spots on the same day. Pete Crow-Armstrong became the seventh member of the 40/40 club and has the NL MVP locked up, potentially adding the home run title. The AL Central race between the White Sox and Cleveland Guardians is tight, with the winner earning the No. 2 seed and a division series bye.

In the NL wild card race, the San Diego Padres, Philadelphia Phillies, and Arizona Diamondbacks are vying for two spots, with complex tiebreakers in play. The Cubs have clinched a playoff spot via tiebreaker scenarios, while the Padres seek the No. 4 seed to host a wild-card series.
