The Sailors revealed their coaching staff for the 2020 season, with three new faces joining the crew. Paul Woodward will replace Paul Davis as pitching coach in Seattle, as Davis will take up a new position as the organization's chief scout strategist. Carson Vitale will be the new pitching coordinator in the major leagues, while Jarrett DeHart will become assistant hitting coach, working alongside second baseman coach Tim Laker .
All three are domestic mercenaries, reaching the big league club after having previously worked at the Mariners Farm System. For the past four seasons, Woodward has risen to partner rank as a pitching coach, most recently serving as a pitching coach for Double-A Arkansas. For the past two seasons, Vitale has been the field coordinator for the junior championships. DeHart has also been with the organization for the past two years, working as a hitting coach for the M team in the Arizona League in 201
The coaching staff as a whole will have a different but familiar appearance as several coaches will take on new roles. Jared Sandberg who was the previous pitching coordinator in the Major League, will now coach Scott Service's bench. Mani Akta, who has been working as a bench coach for the past two seasons and as a third base coach in 2016-17, will once again coach in the hot corner, replacing departing Chris Prieto .
Brian De Lunas is another coach who has resumed his old position as he will get into the job of Bulls coach Jim Brouer in 2019. De Lunas was the Beatles coach in Seattle in 2018, before serving as Director of Development Strategies in 2019.
Laker and the first base / field coach, Perry Hill will return to his same coaching roles in 2020.
