The Mariners on Monday announced their coaching staff for the 2021 season. The unit will remain largely unchanged, although Seattle has appointed Trent Blank as the team’s permanent bullpen coach and director of pitching strategy. He’ll replace Brian DeLunas, whose departure had been previously reported. DeLunas coached remotely in 2020 due to a preexisting kidney issues that place him at high risk with regard to Covid-19. Due to that arrangement, Blank shared bullpen coach duties in 2020 on an acting/interim basis.
Blank is entering his third season with the Mariners organization, having previously been hired as the club’s coordinator of pitching strategy prior to the 2019 campaign. The former Rockies farmhand spent four years with TMI Sports Medicine between his retirement as a player in 2015 and being hired by Seattle.
Manager Scott Servais is set to return to the Mariners for what will be his sixth season, and he’ll have the rest of his 2020 staff back at his side. That includes bench coach Jared Sandberg (heading into his second season in that role), hitting coach Tim Laker (third season), pitching coach Pete Woodworth (second season), first base/infield coach Perry Hill (third season), third base coach Manny Acta (fourth season), assistant hitting coach Jarret DeHart (second season) and field coordinator Carson Vitale (second season).
