Atlanta placed Strider on the 15-day injured list Sunday with a UCL sprain in his right elbow.
The 25-year-old righty underwent an MRI on Saturday that revealed damage to the UCL in his right elbow, so it was only a matter of time before he landed on the injured list. It's unclear at this point if Strider will require Tommy John surgery -- which would be the second such procedure of his career -- but he's likely facing a lengthy absence regardless.
