The Boston Red Sox established the season’s longest winning streak with a franchise-record-tying 15-game run from early July through late July, vaulting them from well below .500 into playoff contention and outpacing every other club’s best stretch. No team has approached that mark since; the next-longest streaks of 2026 reached just 10 games, and recent September form across the league shows short runs at best amid tight divisional races and bullpen usage. With roughly three weeks remaining, any challenger would need an unprecedented 16-plus-game surge to surpass Boston, a barrier reflected in the overwhelming trader consensus favoring the Red Sox. Late injuries, expanded-roster pitching depth, or schedule quirks could theoretically extend another club’s hot spell, though historical patterns make such an outcome remote.
