Svanson will serve as the Cardinals' opening pitcher for the first game of Tuesday's doubleheader with the Brewers, Jeff Jones of the Belleville News-Democrat reports.
Svanson will be making his first MLB start and his first at any level in the professional ranks since 2022, but he's unlikely to cover more than an inning or two before exiting the game. Once Svanson's day is done, left-hander Bruce Zimmermann appears likely to work in bulk relief for St. Louis.
