I like this from Fegan in his recent Atlantic article…
While Grifol is a first-time major-league manager, he is described by friends and colleagues as a baseball lifer who has served in almost every conceivable role during his tenures with the Mariners and Royals — scout, farm director, minor-league manager, roving minor-league instructor, quality control coach, bench coach, catching coach and hitting coach. Hahn said the new manager will play a central role in determining their coaching staff, and those close to Grifol expect him to bring along previous associates. A potential name to watch is Royals special assignment hitting coach Mike Tosar, since he worked closely with Grifol during breakout power-hitting seasons for Jorge Soler and Salvador Perez.
