CHICAGO • The low, murmuring concern the Cardinals had about having enough relievers available for Saturday’s doubleheader was answered early that morning by a move that created a series of uncertainties all its own.
The Cardinals placed starter Carlos Martinez on the disabled list for a second time this season, removing the righthander from the rotation with an oblique strain. Martinez felt a twinge of pain in his right side during the fifth inning of his start Thursday, and received a localized treatment Friday to attack the soreness. The Cardinals were quick to classify the injury as “really, really mild” and draw a distinction between Martinez’s oblique strain and the one that has sidelined starter Michael Wacha for two months.
