Seattle arrives in West Sacramento for the first game of a three‑game series tonight at Sutter Health Park, MLB’s temporary west‑coast home for the Athletics. The Mariners (56‑50) are chasing a wild‑card spot and bring momentum thanks to Cal Raleigh, who already has 41 homers and counting. On the mound is Luis Castillo (7‑6, 3.30 ERA), a dependable front‑line arm hoping to silence Sacramento’s buzz. Across the line is J.P. Sears (7‑8, 4.98 ERA), part of a youthful A’s rotation riding high after a four‑game sweep of the Astros. 

At the plate, rookie sensation Nick Kurtz, fresh off a historic 6‑for‑6, 4‑homers night in Houston, is the story of the moment. Sacramento’s A’s have shed the city name and now anchor their identity purely as Athletics, using this temporary stop to showcase their rebuilding core before the Las Vegas move in 2028. Meanwhile, Seattle’s balanced lineup, led by switch‑hitting leaders and postseason aspirations, faces a Sacramento atmosphere unlike any A’s fans have known in decades. Expect a clash of energy, strategy, and big‑league drama in the series opener.
