The Diamondbacks have announced their coaching staff under manager Torey Lovullo for the upcoming season. Most notably, Jerry Narron will take the open bench coach position. Arizona needed to find a replacement for Ron Gardenhire, who departed recently to become the Tigers’ manager. The organization turned to Narron, who had subbed in for Gardenhire earlier in the 2017 season when the latter was sidelined by cancer treatment.
