Heyman previously reported that the Marlins’ managerial choice would be “outside the box,” and Jennings would be an outside-the-box choice indeed. He coached high school baseball in Alabama before becoming a scout in the 1980s. He has since worked in a variety of scouting and front office roles and does not seem to have coached since then, having joined the Marlins front office in 2002.
There would be limited recent precedent for a team hiring its own GM as manager, particularly when that GM does not have experience in that role. (It is unclear whether Jennings would continue to serve as the Marlins’ GM if he were made manager, a possibility Heyman mentions; there would be similarly little recent precedent for such an arrangement.) One could also note an irony in Jennings replacing Mike Redmond as manager, given that Jennings himself bears responsibility for some of the player personnel moves that have led to the Marlins’ disappointing start this season, such as his trade for Mat Latos and signing of Michael Morse.
Jennings does, however, seem to have the ear of Marlins owner Jeffrey Loria, who promoted Jennings when he fired president of baseball operations Larry Beinfest late in the 2013 season. Jennings’ hire as manager would also be consistent with Joe Frisaro of MLB.com’s recent tweet indicating that the Marlins’ new manager would be a surprising hire from within the organization.
