Drew Ehrhard, a former minor league Red Sox infielder, has been called to the team as an interim bullpen catcher following a staff purge following Alex Cora's departure. Ehrhrhard initially expressed interest in coaching and has since joined the Red Sox big league coaching staff. He has been tasked with assisting in the club's needs and assisting in other tasks such as standing in as a left-handed hitter for Sonny Gray's batting practice session. Despite his transition from minor league player to major league coach, Ehrhardt has been welcomed by several familiar faces at the club.
