What happened: Boston heads into the offseason with a split identity to sort through. One stretch produced a 32-5 run, but the rest of the year left the club 15 games under .500 and complicated any clean read on where the roster stands.
Why it matters: That question matters because Boston already made one major commitment, signing Chad Tracy to a three-year deal after he went 74-55 following Alex Cora's firing. In the AL East, deciding whether to build around the five-week surge or the larger sample will shape payroll, trade priorities and expectations for 2027.
By the numbers: Boston's split is stark: 32-5 during its best burst, 15 games under .500 outside it. Tracy inherited a 12-17 club and went 74-55 the rest of the way before getting the interim tag removed.
What to watch: The next clue will come from how aggressively Boston attacks the winter, especially whether it treats the roster as a contender needing tweaks or a team needing deeper changes.
