Shields won't make his scheduled start Wednesday after the White Sox's game against the Tigers was postponed due to rain, MLB.com's Scott Merkin reports.

EDGE Analysis

With rain descending on Chicago again Wednesday, the White Sox and Tigers will have a game postponed for the second time in the series. Wednesday's game will be made up as part of a straight doubleheader May 26. White Sox manager Rick Renteria hasn't mentioned how the postponement will affect his rotation plans, but it's expected that Shields will simply have his start pushed back a day to Thursday for the series finale, assuming the weather cooperates.
