McGreevy is listed as the Cardinals' scheduled starting pitcher for Tuesday's game against the Rockies at Coors Field.
After being called up from Triple-A Memphis on Wednesday, McGreevy was put to work out of the bullpen a day later in the Cardinals' game against the Pirates. He scooped up the win while tossing three scoreless innings in relief, and he'll now get the chance to enter the St. Louis rotation for the final week of the season due to Lance Lynn (knee) and Sonny Gray (forearm) both recently going on the injured list. Unless the Cardinals elect to expand their rotation to six men by moving Steven Matz from the bullpen, McGreevy will tentatively line up for two starts during the final week of the season. After Tuesday's contest in Colorado, McGreevy would be lined up to take the hill for the finale Sunday in San Francisco.
