The Mariners announced their minor-league coaching staff for 2021, and while there are many familiar faces, there are some new people in new places—figuratively and literally, as the new minor-league alignment will move some teams around. The Mariners also continued their commitment to youth-ening their coaching staff, with new hires that span players fresh off their playing careers to recent college grads.
Starting at the top with Triple-A Tacoma, there’s a surprising promotion right off the bat: 34-year-old Kristopher Negrón, who worked in player development with the big-league club last season and the year before that playing for the Dodgers (and Mariners), will helm the Rainiers.
