Mets set to add Mariano Duncan to coaching staff, per MLB.com

The New York Mets are set to add Mariano Duncan to their major league coaching staff, per MLB.com's Anthony DiComo. Duncan would work with position players in the new role. No formal club announcement has been made.

What happened

Per Anthony DiComo of MLB.com, the Mets are moving to bring Duncan onto their coaching staff in a capacity focused on position players. The report stops short of a club announcement, so the precise title and any formal start date remain unspecified in the available reporting. What is clear is that the organization is actively reshaping its coaching infrastructure as the offseason gets underway.

The move arrives in the same week the Mets were reported to be interviewing Cubs coach John Mallee for a coaching staff position, per MLB.com — a report that surfaced three days before the Duncan news. That sequencing suggests the club is conducting a broader review of its position-player development and instruction pipeline rather than filling a single vacancy in isolation. Coaching staff construction rarely happens one name at a time, and the Mets appear to be working through a deliberate process.

Why it matters

Coaching staff decisions tend to get less attention than roster moves, but they shape how a team develops and deploys its players every single day of a long season. A hire focused on position players carries particular weight for a club that finished 74-88 — a record that invites hard questions about where offensive and defensive instruction has been landing and what needs to change.

Duncan brings a playing background that Mets fans of a certain vintage will remember well. His name carries genuine weight in the organization's history, and his addition to the staff — if the move is finalized — would represent a reunion of sorts with a franchise he has been connected to across different chapters of his career. That kind of institutional familiarity can matter in a coaching context, where trust between instructor and player tends to build faster when the instructor's credibility is already established in the room.

The timing also carries structural significance. Offseason coaching decisions made now set the table for spring training, which is when new instructional relationships actually take root. Getting a position-player coach in place early gives him a full winter to prepare a program, review personnel, and arrive in camp with a plan rather than improvising one on the back fields.

Where the club stands

The Mets finished the season at 74-88 (.457), landing fifth in the NL East, 20 games back of the division leader. They were eliminated from both the division race and the Wild Card race, and they enter the offseason ranked 10th in Wild Card positioning, 14.0 games relative to the cut line. The most recent result was a loss, leaving them on a one-game losing streak as the regular season concluded.

A 74-88 record is the kind of ledger that tends to produce organizational reflection at every level — roster, front office, and coaching staff alike. The Mets are clearly in that mode. The Duncan report and the Mallee interview, taken together, indicate a front office that is not waiting until the calendar turns to begin the work of rebuilding its staff. Whether those two moves represent the full scope of the coaching review or just the first visible pieces of it remains to be seen.

It is worth noting that Francisco Lindor, the Mets' most prominent position player heading into the offseason, won the 2026 Roberto Clemente Award — recognized for community impact and character. The coaching staff that surrounds him and his teammates next spring will matter, and the organization appears to be taking that construction seriously rather than treating it as an afterthought to the roster work.

What we don't know yet

The specific title Duncan would hold has not been reported. Whether this role is newly created or fills a vacancy left by a departing coach has not been addressed in the available reporting. The Mallee interview, reported three days before the Duncan news, has not resolved into a hire or a pass in the material available to the desk, so it is unclear whether the club is pursuing both men for different roles, the same role, or complementary positions on a staff that may be undergoing wider changes.

No timetable for a formal club announcement has been reported. Until the Mets make an official statement, the Duncan addition remains a report, not a completed transaction. Anthony DiComo's reporting at MLB.com is the sourcing on record; the club has not spoken publicly on the matter.

What to watch

The Mallee interview is the most immediate thread to follow. If the Mets move forward with both Duncan and Mallee, the shape of the position-player coaching staff will come into clearer focus. If one hire is announced without the other, it may indicate that the club filled its available opening and moved on — or that the Mallee process is simply running on a different timeline.

The broader question is what the full coaching staff looks like once the offseason settles. A 74-88 season, fifth place in the division, and elimination from Wild Card contention by 14.0 games tends to produce more than one change at the staff level. The Duncan and Mallee reports suggest the Mets are at least partway through a deliberate process of evaluation. Whether that process produces targeted additions or something more sweeping is the story to track through the winter months.

For now, the desk will be watching for the club announcement that converts this report into something official — and for any further names that surface as the Mets continue what appears to be a methodical review of their position-player instruction staff heading into the next season.
