The Seattle Mariners have officially locked in two critical additions to their coaching staff for the 2027 season, moving quickly to solidify the support structure around new manager Jason Kanzler. Less than a week after unveiling Kanzler, the organization announced Monday that former Yankees bench coach Tanner Swanson and former Nationals hitting director CJ Gillman will join the front office. This rapid hiring spree signals the franchise’s intent to build a cohesive, experienced leadership team before the next competitive cycle begins.
New manager Jason Kanzler bolsters staff with Yankees vet and Nationals hitting director.
Swanson brings seven years of Major League experience from his tenure with the New York Yankees, where he served as a bench coach. His appointment provides Kanzler with a seasoned tactical mind to manage in-game strategy and player communication. Meanwhile, Gillman arrives with a fresh perspective after serving as the Washington Nationals’ director of hitting last season. His role as the Mariners’ next hitting coach marks a significant shift in the team’s offensive development strategy, aiming to refine the lineup’s approach at the plate for the upcoming year.
Both hires share a notable connection to Washington state, bridging the gap between their recent out-of-state roles and the local baseball community. Kanzler expressed high confidence in the new duo, stating in a press release, “I am excited to have Tanner and CJ join our coaching staff. Both individuals bring an exceptional understanding of the game and skillsets that I am confident will help maximize the talent on our roster.” These appointments underscore the Mariners’ commitment to leveraging deep analytical and coaching expertise to drive performance in 2027.
