Mikolas (forearm) will make his next rehab start Saturday with Double-A Springfield, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

The right-hander made his last rehab start Sunday and will go nearly a week between appearances, as he rejoined the big-league club this week for a throwing session. Mikolas surrendered seven runs in that previous outing, but he covered 5.2 innings and should be in the mix for the big-league rotation after starting Saturday for Springfield.
