Minor experienced more discomfort in his left shoulder when he threw off the mound during rehab, Mark Bowman of MLB.com reports. Given the nagging nature of shoulder injuries, this could very well be a setback for Minor's return time. If he's behind schedule, his return pushes into May and leaves the Braves with a shallow rotation. When he does come back, he'll be a risky pick-up as he might not be 100 percent and could face re-injury.
