Diamondbacks right-hander Justin Martínez will undergo Tommy John surgery, leading to his absence for the remainder of this season and a significant part of 2026. Initially placed on the 15-day injured list due to a right ulnar collateral ligament sprain, Martínez’s surgery adds to the struggles of Arizona’s bullpen, which has a 5.21 ERA this year. Despite the setback, the extension signed with Martínez includes club options that may become available due to his surgery, although his recovery and return to form remain uncertain.
