Morris lasted just two-thirds of an inning on Saturday, allowing four runs and two hits before an 87-minute rain delay ended his day against the Yankees.
The right-hander leads the NL with four complete games, but has just one win in his last four starts and has an 8.10 ERA during that span.
Morris has not felt 100 percent physically lately, as a “knot” beneath his right shoulder blade has affected his curveball.
With a full five days’ of rest, and more emphasis on running and exercising between starts, the ace believes his arm problems should be past him.
“I have a tendency to slack off sometimes when I’m feeling good,” he said. “I’m going to be better about it from here on. (The knot) is kind of a wake-up call for me.”
Both St. Louis and Kansas City come into their first of back-to-back weekend matchups involved in tight division races.
After taking three of four from the Brewers, the Cardinals are one game behind Chicago in a four-team battle in the NL Central. The Royals, who won three of four against Minnesota this week, are just two games behind the Twins in the AL Central.
“It should be six competitive games,” said St. Louis manager Tony LaRussa, whose Cardinals lead the all-time series 11-10.
STANDINGS: Royals - 2nd place, 2 GB, AL Central. Cardinals - 2nd place (tied), 1 GB, NL Central.
