Sproat and the Brewers won't play the Cardinals on Tuesday, as the game was postponed due to inclement weather, Jeff Jones of the Belleville News-Democrat reports.
The two sides will play a doubleheader July 7 to make up for Tuesday's contest, and Sproat will likely get the nod to start Wednesday's series finale. The 25-year-old has struggled to begin his time with the Brewers, posting a 6.75 ERA and 1.61 WHIP through his first 26.2 innings.
