St. Louis Cardinal right-hander Joe Kelly will make a rehab start this Friday at AutoZone Park against the Round Rock Express. Kelly has been out of action since landing on the disabled list back on April 17 with a left hamstring strain. He last appeared in a Redbirds uniform in 2012 when he posted a 2.86 ERA in 12 starts. Kelly is expected to throw 40-60 pitches in his rehab start.
