The Indians’ pitching coach and the Mets have agreed on a three-year deal for the 42-year-old former pitcher to succeed Terry Collins, who was not offered a contract after seven seasons at the helm.

If the Mets’ GM isn’t going to call the 2018 team a rebuild but a “reset,” well at the very least he needed to make it a fresh reset that brought energy back to the organization.

Alderson said the Mets are reorganizing their medical and training staff — long-time head trainer Ray Ramirez was let go — but at the same time controversial strength and conditioning advisor Mike Barwis is still involved.

He is credited with improving Indians pitchers Trevor Bauer and Mike Clevinger and has guided Cy Young winner Corey Kluber.

Indians manager Terry Francona, who hired Callaway despite having never heard of him before going to Cleveland, thought so highly of Callaway’s contribution to the Indians’ 2016 World Series run that he included him in an ALCS press conference to make sure he got credit.
