The Mariners have unveiled their coaching staff for the 2020 season, with three new faces joining the crew. Pete Woodworth will replace Paul Davis as Seattle’s pitching coach, as Davis will take on a new position as the organization’s chief pitching strategist. Carson Vitale will be the team’s new Major League field coordinator, while Jarret DeHart will become the assistant hitting coach, working alongside second-year hitting coach Tim Laker.
All three are internal hires, coming up to the big league club after previously working in the Mariners’ farm system. Woodward has been moving up the affiliate ranks as a pitching coach for the last four seasons, most recently serving as the pitching coach for Double-A Arkansas. Vitale has been the Mariners’ minor league field coordinator for the last two seasons. DeHart has also been with the organization for the last two years, working as the hitting coach for the M’s Arizona League team in 2018 and spending last season as a roving minor league hitting strategist.
The coaching staff as a whole will have a different yet familiar look, as several incumbent coaches will be taking on new roles. Jared Sandberg, who was the previous Major League field coordinator, will now be Scott Servais’ bench coach. Manny Acta, who worked as bench coach for the last two seasons and as the third base coach in 2016-17, will be coaching at the hot corner once again, replacing the departing Chris Prieto.
Brian De Lunas is another coach resuming an old position, as he will step into the bullpen coach job that was held by Jim Brower in 2019. De Lunas was Seattle’s bullpen coach in 2018 before working as director of pitching development strategies in 2019.
Laker and first base/infield coach Perry Hill will both be back in their same coaching roles in 2020.
