Mets Promote Mariano Duncan To Major-League Staff

As the New York Mets slightly revamp their coaching staff, they are elevating one of their minor-league staffers to the majors.

Mariano Duncan, the bench coach at Double-A Binghamton, has been promoted to the MLB staff, Joel Sherman of the New York Post reported Monday. While Sherman didn't mention a specific title, Duncan is expected to have a wide-ranging role with the Mets' position players.

Duncan, 63, played for 12 years in the majors, mostly as an infielder, and won a World Series with the 1990 Cincinnati Reds and 1996 New York Yankees, while also making the Fall Classic with the 1993 Philadelphia Phillies. Duncan was an All-Star with the Phillies in 1994.

In addition to being with Binghamton in 2026, he was also with the Rumble Ponies in 2022 and with the Brooklyn Cyclones in 2021, the Mets' High-A Affiliate. Duncan has served in a variety of coaching roles since 2003 at all levels, from the Gulf Coast League up to Triple-A.

The Mets recently said three coaches would not be returning to the major-league staff, which is the first under Andy Green, who took over as interim manager during the season and was given the full-time job at the end of the year.
