The Mets relieved manager Mickey Callaway of his duties on Thursday, and the club will also not be retaining bench coach Jim Riggleman, SNY's Andy Martino confirmed.
GM Brodie Van Wagenen said during a conference call earlier Thursday that decisions on the coaching staff would be made on a case-by-case basis.
The 66-year-old Riggleman was brought on last offseason in part to help Callaway with the strategic ins and outs in-game. He replaced Gary Disarcina, who became the Mets' third base coach when Van Wagenen reorganized the team's coaching staff.
"Jim brings a wealth of experience to the coaching staff," Van Wagenen said at the time of Riggleman's hiring. "His familiarity with the National League will be a great asset."
Before joining the Mets, Riggleman had been with the Reds organization since 2012. He was the team's third base coach from 2015 to 2018. Riggleman is 726-904 during his career as a manager, which has included stops with the Padres, Cubs, Mariners and Nationals.
