Cooper Hjerpe couldn't have asked for a much better MLB debut. The 25-year-old lefty entered in relief against Colorado and would go on to fire four perfect innings with six strikeouts, earning the win in a 10-8 St. Louis Cardinals victory. “It was unbelievable,” Hjerpe said postgame. “It was a great experience, great debut.”
