Ryan Walker seizes the Giants’ closer role as Randy Rodríguez heads to season-ending Tommy John surgery, pivoting the club’s save chances for the final weeks. Shawn Armstrong takes reins in Texas’ late innings, while Andrés Muñoz, Edwin Díaz, and Aroldis Chapman anchor the top tier with dominant numbers. Jhoan Duran, Robert Suárez and Daniel Palencia juggle high-leverage opportunities in varied roles. Abner Uribe, Tanner Scott, Emilio Pagán, Raisel Iglesias and others provide depth across tiers, shaping fantasy late-season bullpen strategies.
