The Brewers are acquiring Dustin May and JoJo Romero from the Cardinals, sources tell The Athletic.

Alexander Frias and Josiah Ragsdale are going to St. Louis, according to MLB.com’s Adam McCalvy. May could replace Robert Gasser in the Brewers rotation or the team could shift back to a six-man setup for now. Romero will take some pressure off Aaron Ashby in relief once he comes off the IL.
