The Seattle Mariners have added Tanner Swanson to their coaching staff, bringing the former New York Yankees major league field coordinator and director of catching to the organization.
Swanson, who oversaw catching development and field coordination for the Yankees, joins the Mariners after spending time with the New York franchise. The move reunites Swanson with the Mariners, where he is expected to contribute to the team's catching and defensive strategies.
