The Seattle Mariners are hiring Jason Kanzler, the Chicago Cubs' director of player development, as their new manager, the club announced on Tuesday.
Kanzler, 36, succeeds Dan Wilson, the longtime catcher who oversaw one of baseball's most disappointing teams this past season. The Mariners made it all the way to Game 7 of the American League Championship Series in 2025 and were a popular pick to advance to their first World Series in 2026 but never got it together, ultimately finishing 76-86 and failing to make the playoffs despite playing in a mediocre division.
Kanzler will inherit one of baseball's deepest, most talented teams, one stocked with starting-pitching depth and headlined by two superstars in Cal Raleigh and Julio Rodriguez.
