Red Sox searching for new first- and third-base coaches ahead of 2027

The Boston Red Sox are heading into the offseason with two coaching vacancies to fill, per MLB.com's Ian Browne: the club needs new first-base and third-base coaches ahead of the 2027 season.

What happened

Ian Browne of MLB.com reported that the Red Sox are replacing both their first-base and third-base coaches before next season gets underway. No successors have been named, and the report does not identify the outgoing coaches by name or specify the circumstances of the departures. What is clear is that Boston enters the offseason with two prominent spots on the field staff open — the kind of vacancies that tend to generate a quiet but purposeful round of phone calls in October.

Why it matters

Base coaches are not the most glamorous line item on a major-league staff, but they are operationally significant in ways that show up in the box score without a byline. The third-base coach is the last human checkpoint on every scoring decision — the wave, the hold, the split-second read on an outfielder's arm — and the first-base coach manages the running game on the other end, communicating signs, monitoring pickoff tendencies, and keeping baserunners engaged. Replacing both simultaneously means the Red Sox are rebuilding that entire layer of in-game decision-making at once.

For a club that finished 87-75 (.537) and ranked second in the American League Wild Card standings, the margin for operational error is not wide. Boston ended the season 11 games back in the AL East and eliminated from the division race, which means the Wild Card path was the only route to October. Baserunning decisions — the ones these two coaches own — can be the difference between a run that scores and an out that ends an inning, and in a Wild Card race measured in single games, those moments accumulate.

The offseason search will draw attention not just for who gets hired, but for what the choices signal about the direction of the staff under the current regime. Coaching hires at the base level often reflect organizational philosophy: aggressive or conservative on the bases, analytically integrated or more instinct-driven. Boston's choices here will be worth watching for exactly that reason.

The numbers

The Red Sox closed the 2026 regular season at 87-75 (.537), sitting third in the AL East and second in the Wild Card standings with a +3.0 margin relative to the cut line. The season ended on a one-game losing streak. The division race was not in play by the end; the club was eliminated from that chase while still alive in the Wild Card picture.

Where the club stands

Boston finished 87-75 (.537), third in the AL East, 11 games behind the division leader, and second in the AL Wild Card race at +3.0 relative to the cut line. The season is over, and the club now turns to an offseason that already has several moving pieces beyond the coaching search.

The injury ledger heading into the winter is not short. Zack Kelly's elbow injury, initially characterized as inflammation, was revealed to be a fracture; he is on the 60-day IL and his return timeline remains unclear. Caleb Durbin underwent surgery to repair a lingering left pinkie injury, raising availability questions for the Red Sox infielder. Neither situation has a firm resolution date attached to it, which means the front office is managing personnel uncertainty on the player side at the same time it is conducting a coaching search.

That is a fairly full offseason plate, even by the standards of a franchise that rarely sits still between October and February.

What we don't know yet

The report does not name the coaches who are departing, does not specify whether the separations were mutual, and does not indicate a timeline for filling the roles. No candidates have been publicly identified. It is also not yet clear whether the club intends to promote from within its system, look to other organizations, or pursue coaches with prior major-league experience in those specific roles.

The injury situations for Kelly and Durbin remain open questions as well. Kelly's fracture carries an unclear return timeline, and Durbin's surgical recovery has not been assigned a target date in the available reporting. Both situations will bear on how the Red Sox construct their roster heading into spring training, separate from but parallel to the coaching search.

What to watch

The first names attached to the first- and third-base coaching searches will tell a story about organizational priorities. Watch for whether Boston moves quickly — some clubs treat base coaching vacancies as lower-urgency fills and let the search run deep into the winter — or whether the front office signals that it wants continuity and experience in place early, giving a new staff time to build chemistry before camp opens.

The Durbin and Kelly situations are worth monitoring on their own timelines. Durbin's surgery and Kelly's fracture both carry uncertainty that will shape Boston's roster construction decisions, and any updates on either front will clarify how much flexibility the club actually has heading into 2027.

And for the broader picture: a club that went 87-75 and reached the Wild Card threshold is not rebuilding. It is retooling at the margins, and coaching hires — even the ones that don't make the back page — are part of that process. The Red Sox are not tearing anything down. They are, apparently, starting with the baselines.
