The Athletics placed Kaprielian (shoulder) on the 10-day injured list Thursday, Matt Kawahara of the San Francisco Chronicle reports.
Kaprielian's move to the IL was a formality after he didn't make any Cactus League appearances following the diagnosis of AC joint inflammation in his right shoulder early in spring training. The 28-year-old was able to complete a 30-pitch live batting practice session Tuesday, so he could be ready to head out on a minor-league rehab assignment as soon as next week if his shoulder continues to respond well. He'll likely need at least two or three outings in the minors to get fully stretched out for starting duty with the big club.
