According to a report from Joel Sherman of the New York Post, the Mets are adding Mariano Duncan to their major league coaching staff. Sherman writes that Duncan “is expected to help in multiple areas with the position player group.”
Duncan has been a coach in the Mets’ Minor League system since 2019, serving as hitting coach for the formerly Rookie-class Kingsport Mets before taking over as bench coach for the High-A Brooklyn Cyclones in 2021 and later the Double-A Binghamton Rumble Ponies in 2022.
Excluding rehab assignments, he has previously coached seven position players on the Mets’ current 40-man roster (including Brett Baty and Francisco Alvarez, who played with the Kingsport Mets during their debut pro seasons in 2019).
The 63-year-old enjoyed a 12-year big league career as a utility player from 1985-97, winning a pair of World Series (with the Reds in 1990 and the Yankees in 1996) and notching one All-Star selection (with the Phillies in 1994). He also finished third in Rookie of the Year voting with the Dodgers in 1985.
The Mets still have a few more slots to fill on manager Andy Green’s coaching staff before Spring Training arrives, as they parted ways with a trio of coaches at the conclusion of the 2026 season.
