What happened: Atlanta secured the National League East title, and Boston clinched an American League Wild Card berth. The outcomes guarantee both clubs a spot in the 2026 postseason.

Why it matters: The result caps a late-season surge for the Red Sox, who sat in the AL East cellar in July. Atlanta adds another division championship to its ledger as both rosters prepare for October.

What to watch: Both clubs will finalize their playoff seeding over the remaining regular-season schedule.
