The Mariners just named Jason Kanzler their new manager, and if that name sounds familiar, it should sting a little for the Emerald City. This is the guy who was on the Astros coaching staff back in 2022 when they swept *our* Mariners in the AL Division Series on their way to a World Series win. Talk about an unexpected twist for the 19th full-time manager in club history! Seattle general manager Justin Hollander isn’t just bringing in some random new face; he’s bringing in someone he says “dominated the process” of hiring from start to finish.
From Medical School to the Manager’s Office, This Guy’s Journey is Wild
Seriously, Kanzler’s path to T-Mobile Park is unlike anything we’ve seen. He actually considered medical school after high school, and then walked onto the Buffalo team as an outfielder, earning two Rawlings Gold Gloves. After the Minnesota Twins picked him in the 20th round of the 2013 MLB Draft, he spent three seasons in the minor leagues. But when his playing career wrapped up, he didn’t jump right into coaching. Nope, Kanzler became a high school physics and chemistry teacher in Katy, Texas! He said it “felt natural” because he loved helping teammates improve, and he fully intends to carry that “incredibly rewarding” experience into his new gig with the Mariners.
Baseball kept pulling him back though. He joined the Houston Astros as a minor league hitting coach in 2019, eventually getting promoted to manager Dusty Baker’s coaching staff in 2022. That, of course, was the same year the Astros won the World Series, beating the Mariners in that painful ALDS sweep. Before landing here, Kanzler was the director of player development with the Chicago Cubs starting before the 2024 season. Hollander was straight up about why Kanzler got the job, citing his “dynamic personality” and his “analytics-forward player-development” background. Hollander said Kanzler “left us no choice throughout the process” and that they “would’ve been foolish to take all that hard work and throw it out the window.” That’s high praise, people.
Dipoto’s Third Spin at the Managerial Wheel Comes with a Data-Driven Shift
This isn’t the first time Kanzler was on Seattle’s radar; they interviewed him back in 2021 for a major league hitting coach role. And for Jerry Dipoto, the Mariners’ president of baseball operations, this marks his third manager hire during his 11-year tenure, with all three (Scott Servais in 2015, Dan Wilson in 2024, and now Kanzler) having no prior managing experience. Dipoto admitted he’s learned a lot since that first hire, involving “far more of our baseball operations team” in the process this time around, asking “far deeper questions.” He even joked, “I hope it’s at least another decade before we have to go through that again.”
The move comes after the Mariners fired Dan Wilson following a disappointing 76-86 finish this season. That stung, especially after the club had high expectations coming off an American League Championship Series run that went all the way to Game 7 in 2025. It seems Kanzler’s “analytics and data-friendly background” was exactly what the club was looking for to course correct. What a pivotal moment for the Emerald City squad. Can Kanzler’s unique journey and data-first approach be the spark this team needs to not just meet, but exceed, those expectations next season? The clock is already ticking.
