Mets make midseason change, Carlos Mendoza fired; Andy Green named interim manager

The New York Mets have fired manager Carlos Mendoza, a move first reported by Jon Heyman of the New York Post and then reflected in a quick Mets announcement, according to MLB Trade Rumors on June 26. Andy Green, who had been with the club in a player development role, is expected to take over as interim manager for the remainder of the season. The timing underscores how quickly the Mets’ season has shifted from planning to damage control.

Mendoza’s dismissal puts a sudden spotlight on the organization’s short-term leadership needs. In MLB, midseason manager changes often aim to reset communication, stabilize clubhouse routine, and tighten on-field decision-making during a stretch where teams are either pushing for a postseason opening or trying to salvage what remains of their division and wild-card chances. For the Mets, the move indicates the club believes the tipping point has arrived.

Green’s appointment is notable for the background he brings from inside the organization. MLB Trade Rumors reports that Green was already in a player development role with New York, meaning the transition is not simply an external hire. He now moves from overseeing parts of the developmental pipeline into the day-to-day responsibility of managing games, setting lineups, and directing in-game adjustments from the dugout.

The interim nature of Green’s assignment is also central to how the rest of the season could play out. Interim managers typically face a narrow mandate: lead through the final games, create clarity for players, and provide consistent messaging while the front office evaluates what comes next. The Mets have not been described as making a long-term staffing decision in this reported change, but Green’s interim role will likely shape how New York’s players respond to a new voice and new structure.

The decision arrives with the Mets, by reporting description, in a “disastrous” season arc that has reached a tipping point. While MLB Trade Rumors does not add statistical specifics in its preview, the managerial firing itself is the clearest, organization-level statement that results have not matched expectations. In that context, the change can also affect how players view the season’s last stretch, particularly younger players and fringe regulars who may be trying to translate opportunity into more stable roles.

There are also broader organizational implications. When a team replaces a manager, it often re-centers how the coaching staff aligns with the manager’s approach to handling pitchers, positioning matchups, and managing bullpen resources. Even without detailing specific tactical shifts, a change like this can ripple through the clubhouse, especially for veterans used to particular habits and for prospects and developing players who are learning a system alongside a staff.

What to watch next is straightforward but important. Green’s first decisions as interim manager, how quickly the Mets’ on-field fundamentals stabilize, and whether the player development-to-major-league transition translates into a different feel in day-to-day preparation will be closely followed. Just as significantly, the organization’s next step after the season will matter, since this firing is likely to influence the timing and profile of any full-time managerial search.
