The Mets will hire Dave Eiland as pitching coach, sources told Newsday on Wednesday night, the latest move in what has been a shake-up of the coaching staff under new manager Mickey Callaway. Earlier, industry sources confirmed that Pat Roessler will stay on board and be promoted to hitting coach. He will replace former hitting coach Kevin Long. After being passed over for the managerial opening, Long is not expected to remain in the organization, as Newsday first reported. Roessler, 57, served as the assistant hitting coach under Long, who has reportedly surfaced as a hitting coach candidate for both the Nationals and the Yankees. Roessler and Long have ties dating to their days working in the Yankees organization. Both joined the Mets before the 2015 season.
