Moustakas (thumb) was diagnosed with a fracture in his thumb and placed on the 15-day DL on Saturday, Jeffrey Flanagan of MLB.com reports.
Moustakas missed two games early in the week with a swollen thumb, but he returned to action Wednesday, going 0-for-3 at the plate. The third baseman was then scratched from the lineup Friday, and he'll now hit the DL with the fracture obviously requiring more than a few days off to heal. It's unclear how long the Royals expect Moustakas to remain out, but considering the diagnosis, it's possible he could miss time beyond the allotted 15 days. To fill Moustakas' spot on the roster, Kansas City recalled infielder Cheslor Cuthbert from Triple-A Omaha. He and Christian Colon figure to handle third base as long as Moustakas remains out.
