Derrick Goold of the St. Louis Post-Dispatch reports that Michael Wacha won’t start on Sunday as scheduled. Marco Gonzales will be asked to toe the rubber against the Rockies instead. Manager Mike Matheny said Wacha “doesn’t look right.”
Wacha, 23, has gone only three and four innings in his two starts since returning from the disabled list on September 4. He was sidelined for two and a half months with a stress fracture in his right shoulder. In 17 starts overall this season, Wacha has a 3.14 ERA with an 89/30 K/BB ratio.
Gonzales has made four starts and two relief appearances in the majors for the Cardinals this season and has a 5.01 ERA to show for it.
