He was named the assistant director of pitching in 2024 and was promoted to director of pitching development in 2025.
Bleich is the second member of the baseball operations department to take an assistant general manager job with another team this offseason. Former amateur scouting director JustinHorowitz did the same thing in joining the Nationals as their assistant GM.
