The Red Sox may have already lost assistant general manager Jed Hoyer to the Padres and bench coach Brad Mills to the Astros, but they won't be losing director of player development Mike Hazen.

According to a baseball source, Hazen will be remaining with the Red Sox. His duties won't change, though he will be granted some more autonomy based on the changing role of assistant general manager Ben Cherington. With the departure of Hoyer, Cherington will move from overseeing amateur scouting and drafting and player development to focusing more on the major league club.
