PEORIA, Ariz. -- The equipment truck has already departed for Seattle, the few roster battles that were in the works have mostly been decided and the final cuts are in the works. The Mariners still had one more Cactus League game -- they lost, 10-3, on Monday to the Padres

SEATTLE -- The Mariners are adding a new jolt of energy to one of their most recognizable in-game traditions, albeit a newer one, and doing so with a hometown partner. In a collaboration announced Monday, the Mariners and Brooks Running will bring a performance-driven twist to the Microsoft Salmon Run,

PEORIA, Ariz. -- Mitch Garver, who was a late addition to Mariners camp on a Minor League deal and as a non-roster invite, has won the backup catcher job, a source familiar with the club’s thinking told MLB.com on Sunday morning. Garver had been up against fellow veteran Andrew Knizner,

PEORIA, Ariz. -- For all the rigors he takes, Cal Raleigh has often brushed them off by saying “motion is lotion.” And that’s been especially true for the Mariners’ all-world catcher since returning to Spring Training from the World Baseball Classic on Thursday -- even as temperatures have reached historic

PEORIA, Ariz. -- It won’t quite be show-and-go for the Mariners’ eight players at the World Baseball Classic who are expected to be on the club’s Opening Day roster. But it will still be a tight turnaround by the time they all return for the final days of Spring Training

PEORIA, Ariz. -- Bryce Miller’s first full-effort bullpen session since suffering left side oblique inflammation was cut short before it got going on Wednesday afternoon, making an already tight window to break camp on the Opening Day roster even tighter.
