On August 1, with the Red Sox again mired in last place at 47–58, Lucchino announced his intention to retire as president/CEO at the end of the season. Seventeen days later, the Red Sox named veteran MLB executive Dave Dombrowski to the new position of president, baseball operations, to oversee Cherington and the on-field side of the Boston organization. Cherington then turned in his resignation, declining the club's request that he remain as the team's general manager. By that time, only one of the 2013 free agents, injured closer Uehara, remained on the Red Sox' roster. However, Cherington left behind a group of young players (Xander Bogaerts, Mookie Betts, Brock Holt, Eduardo Rodríguez, Blake Swihart, Travis Shaw, Henry Owens, Christian Vázquez, and others) as a potential core of their 2016 team. Much of this core that Cherington acquired contributed heavily to the Red Sox's 2018 championship. Five weeks later, Mike Hazen, one of Cherington's assistants, was named his successor.
