It is doubtful Cardinals starter Jaime Garcia will make his next scheduled start after he left Houston and returned to St. Louis on Wednesday morning to have his left shoulder examined for a possible injury. The results of exams and tests will determine if Garcia will go on the disabled list.  Garcia missed his scheduled start last Friday with what was described as a sore elbow. Garcia struggled in his start at Houston, giving up six runs in his shortest outing of the season.
