The Seattle Mariners have announced the coaching staff for all of their minor league affiliates.

And one coaching staff will be tasked with leading the Mariners' Low-A team to their third-straight championship. It will also be the last time that club will be a part of the Seattle organization.

The Mariners announced their coaching staff for the Modesto Nuts on Jan. 16. The team will have a new manager after Baseball America's Minor League Manager of the Year, Zach Vincej, took the same role with Seattle's High-A team, the Everett AquaSox.

The Nuts' new skipper in 2025 will be Luis Caballero. Josh Morgan will be the bench coach, Brock Stassi will be the hitting coach, Jakob Witt will coach pitchers, Luke Carlson will be the strength and conditioning coach, Blake Wooten will be the athletic trainer and Cameron Werme will be an athletic training fellow.

Caballero was a minor league player from 2010-15 but never saw major league time. From 2017-2021, Caballero was on the coaching staff for Seattle's Dominican Summer League team. He was the manager for the organization's Arizona Complex League team from 2022-24.

Modesto will undergo a different moniker after 2025. The Mariners sold the team to Diamond Baseball Holdings earlier in the offseason. The club will relocate to San Bernardino, Calif., in 2026. They will become the Inland Empire 66ers and re-affiliate with Seattle in 2026 under the new banner.

Modesto has been the class of the California League the last two seasons. One of Seattle's top prospects, Lazaro Montes, was named the league's Player of the Year in 2024.

Caballero will have a new influx of new talent to work with such as switch-pitcher Jurrangelo Cijntje and right-handed pitcher Ryan Sloan.

There might just be enough new and returning players for the Nuts to bring home a third-straight California League championship before moving south to San Bernardino.
