Overview

• The Modesto Nuts, a Class A affiliate of the Seattle Mariners, will move to San Bernardino in 2026 and be rebranded as the Inland Empire 66ers.
• The relocation follows the Mariners' sale of the team to Diamond Baseball Holdings, which now owns 41 minor league teams across the U.S.
• Modesto and the Mariners failed to reach a long-term lease agreement for the city-owned John Thurman Field, which required $32 million in upgrades to meet MLB standards.
• The move is part of a broader reorganization of California League teams, with the Dodgers and Angels also realigning their minor league affiliates in the region.
• Modesto officials plan to explore alternative uses for John Thurman Field, as the city prepares to bid farewell to its only professional sports team.
