Which is why it's hard to believe that Aaron Ashby, a 27-year-old starter-turned-reliever, has been the unquestioned MVP of the group this season. Ashby's addition to the bullpen in late May coincided with the beginning of the Brewers' winning ways in 2025. In fact, since Ashby was added to the 'pen on May 23, the Brewers have the second-best reliever ERA in all of baseball. Prior to May 23, they ranked 23rd in baseball in reliever ERA. Therefore, while Uribe likely gets the award for most effective reliever in the Brewers' bullpen this season, with a 1.82 ERA to prove it, and Megill earned his first All-Star nod this season, it's Ashby, who completely transformed the bullpen, that takes home the bullpen MVP award in 2025.
