With the 2026 MLB regular season concluding on September 27, the final two postseason berths remain undecided in the AL West and NL Wild Card. Ten teams have already clinched spots, including division winners Tampa Bay Rays, Cleveland Guardians, Milwaukee Brewers, Los Angeles Dodgers, and Atlanta Braves, plus wild-card qualifiers New York Yankees, Boston Red Sox, Chicago White Sox, San Diego Padres, and Chicago Cubs. The Astros hold a narrow edge over the Rangers for the AL West title, while the Phillies lead the Diamondbacks by one game for the NL's last wild-card spot, with tiebreakers and head-to-head records in play. Sunday's results in key matchups, such as Astros vs. Athletics and Rays vs. Phillies, will finalize the 12-team field and shift implied probabilities accordingly.
