The San Diego Padres are finalizing a deal to acquire standout reliever Mason Miller and starting pitcher JP Sears from the Athletics, according to sources familiar with the negotiations.

How the Padres Strengthen Their Roster

Miller, known for his triple-digit fastball and dominant presence on the mound, has been one of the most electrifying young arms in baseball this season. Sears, a left-hander with solid command and versatility, adds depth to the Padres’ rotation.

The move signals San Diego’s intent to make a serious postseason push, bolstering both the bullpen and starting staff as the trade deadline approaches. Details on the return package headed to Oakland have not yet been disclosed.
