Hazen remained with the Red Sox through the 2016 season before assuming the role of executive vice president and general manager of the Arizona Diamondbacks. Dombrowski surrounded himself with faces familiar to him, including Frank Wren and Tony LaRussa, who both provided counsel on personnel and scouting issues.
His decision to enter 2019 without an established closer after parting ways with Craig Kimbrel proved to be fatal. The combination of Brandon Workman, Ryan Brazier and Matt Barnes have not been able to replicate the consistent success Kimbrel provided after he was acquired in a deal Dombrowski brokered with the San Diego Padres before the 2016 season.
Dombrowski is responsible for the deals that brought Craig Kimbrel, David Price, Chris Sale, JD Martinez, Nathan Eovaldi, Steve Pearce and Mitch Moreland to Boston, among others.
