Yesterday, the Mariners announced their minor league coaching staffs for each of the various affiliates. Most of the names are familiar, but there are a few standouts both in new hires and in people being reshuffled at various levels of the organization. Like they’re doing on the field, the Mariners are going younger with their coaching staff. They’re also following an industry trend in the recruiting talent outside of the realm of ex-pro players; as we’ve seen #HittingTwitter stars like RA Parker and Jason Ochart get scooped up by MLB teams, the Mariners have quietly added coaches of a similar background who run their own baseball academies, similar to the hiring of Brian DeLunas last season.
