Breslow attended Hebrew school in his youth and celebrated his bar mitzvah in 1993. As captain of the Yale Bulldogs baseball team, he was an All-Ivy Leaguer with consistently outstanding numbers. As aspiring physician, Breslow deferred acceptance to medical school at NYU after being selected by the Milwaukee Brewers in the 26th round of the 2002 amateur draft. Breslow debuted with the San Diego Padres and bounced around the league with a reputation for being a “lefty specialist,” but ultimately found fairly stable work in Oakland and Boston where he saw consistently steady work in a set-up role. As a key piece of the bullpen, Breslow helped the 2013 Red Sox breeze through the playoffs and earn a World Series championship.

He has a reputation for being highly intelligent and very charitable. He was the Chicago Cubs’ assistant general manager from 2020-23 before taking over as the  Boston Red Sox’s director of baseball operations.
