With the 2026 MLB regular season entering its final week, six teams have already clinched postseason berths—the Rays, Yankees, and Red Sox in the AL alongside the Brewers, Dodgers, and Braves in the NL—while the remaining spots hinge on tight divisional and wild-card races. In the AL, the Guardians hold a one-game edge over the White Sox for the Central title and a likely wild-card spot, the Rangers lead the Astros by one in the West, and the White Sox sit three games clear of the Astros and Blue Jays for the final wild-card berth. The NL wild-card picture features the Cubs and Padres tied atop the standings with the Phillies just one game back, as the Diamondbacks trail by four. Recent momentum, head-to-head results, and remaining schedules will determine final seeding and the three open berths before wild-card play begins September 29.
