Terry Collins is out, but will assist Sandy Alderson in an advisor role.
Dan Warthen will not be the Mets pitching coach in 2018, and there is conflicting information on what he will do in 2018 with the Mets, if anything at all.
Ray Ramirez, the Mets lead trainer since 2005, is also out.
All other coaches and members of the training staff will remain with the Mets in 2018.
