Brad Keller and Andrew Kittredge form a Cubs late-inning committee after Palencia hits the IL, creating a two-headed path to saves with fireman duties sprinkled in. Dennis Santana remains the Pirates’ closer, and JoJo Romero with Riley O’Brien share Cardinals late-inning leverage, offering mixed saves and holds as playoff rosters tighten. Ranger arms Shawn Armstrong and Phil Maton are splitting saves, with Trevor Megill’s looming return for Milwaukee reshaping the back end. In deeper leagues, Arizona’s bullpen shows leverage ladder activity behind Woodford, Saalfrank, and Thompson.
