The Mariners on Monday announced a series of departures and promotions as they set their coaching staff for the 2022 season. Manager Scott Servais was already known to be returning after agreeing to a multi-year extension on Sept. 1, but there will be some changes on his staff.
Tony Arnerich, who has spent the past two seasons as the team’s minor league field coordinator and catching coordinator, will be one of two co-hitting coaches on next year’s club. Also being promoted to the role of hitting coach and to the broader title of director of hitting strategy is Jarret DeHart, who was an assistant hitting coach in each of the past two seasons.
Seattle is also adding longtime director of player development Andy McKay to the Major League coaching staff, where he’ll be in uniform and serve as a Major League coach and senior director of baseball development. It’ll be his first year on the coaching staff but his seventh in the organization.
