Seattle Mariners have appointed Jason Kanzler as the franchise's 22nd manager, the club announced on Tuesday. Kanzler joins Seattle after serving as a coach with the Houston Astros, where he was part of the staff during the 2022 season.
The hiring was reported by John Trupin of SB Nation on November 3, 2026. Kanzler, who appeared in team photos for the Astros during spring training in West Palm Beach, Florida, on March 16, 2022, brings major league coaching experience to the Mariners dugout.
Seattle's decision to hire Kanzler marks a new chapter for the organization as they look to build on recent seasons. The 22nd manager in club history will be tasked with leading the team's next competitive cycle.
