Which 2026 MLB deadline candidate made his major league debut for the Boston Red Sox in 2015? Eduardo Rodríguez did.

Rodríguez debuted on May 28, 2015, starting for Boston against the Texas Rangers at Globe Life Field. He earned the win in a 5–1 victory, allowing three hits and striking out seven. The left-hander’s arrival was especially notable because he opened his career with three strong starts, each lasting at least six innings while allowing no more than one earned run.

Rodríguez originally signed with the Baltimore Orioles as an international free agent in 2010. Boston acquired him from Baltimore in July 2014 in the trade that sent reliever Andrew Miller to the Orioles. After developing in the Red Sox farm system, Rodríguez reached the majors the following season.

A common mix-up is confusing his 2015 debut with his later tenure in Detroit. Rodríguez remained with Boston through 2021, won a World Series with the club in 2018, and later signed with the Tigers before joining the Arizona Diamondbacks.
