NEW YORK -- Luis Rojas is about to have at least one new member of his coaching staff. Bench coach Hensley Meulens will not return to that position in 2021, a source confirmed, putting the Mets in line to employ their fifth bench coach in the last five seasons.

Meulens, 53, was hired to be manager Carlos Beltrán’s right-hand man after working with Beltrán as a player when both were in the Giants' organization. The Mets retained Meulens to serve as Rojas’ bench coach when the latter became New York’s replacement manager, but Meulens wound up lasting only one season.

The Mets have not publicly stated the fates of other coaches -- including hitting coach Chili Davis and pitching coach Jeremy Hefner -- following wholesale ownership and front office changes. Other coaches on Rojas’ 2021 staff included Gary DiSarcina, Tony DeFrancesco, Brian Schneider, Ricky Bones, Tom Slater and Jeremy Accardo.

The Mets’ bench coach position in general has seen high turnover in recent seasons. Following the departure of Dick Scott in 2017, the Mets hired DiSarcina, but decided a year later that manager Mickey Callaway would benefit from more experience in the dugout. The team turned next to Jim Riggleman, who did not survive Callaway’s departure, then to Meulens.

General manager Sandy Alderson indicated last week that he and Rojas intended to complete their coaching staff decisions by mid-December.

Darling’s good deeds
Mets broadcaster Ron Darling will serve as a celebrity ambassador on Tuesday in a trading event to benefit Tuesday's Children, the organization formed in the wake of 9/11 to help families affected by terrorism, military conflict or mass violence. The Mets have maintained a close relationship with Tuesday’s Children since its founding in 2001.
