Several MLB teams are gearing up for significant postseason contributions from their bullpen arms. Tommy Edman has been a key player for the Dodgers, showcasing a powerful return with a strong performance since coming off the IL. Pittsburgh Pirates' Carmen Mlodzinski has been exceptional, improving his ERA and FIP while not allowing any walks in September. The Kansas City Royals' Kris Bubic, Milwaukee Brewers' Aaron Ashby, and Houston Astros' Kaleb Ort have also been highlighted as potential game-changers in October. Bubic has transitioned successfully to a bullpen role, Ashby has shown dominance after surgery, and Ort has transformed his performance with the Astros.
