Castillo was placed on the 10-day injured list with right shoulder inflammation Saturday, retroactive to Aug. 20.

EDGE Analysis

Castillo was charged with a blown save Thursday when he allowed two runs on a hit and a walk while striking out two in one inning, and his injury helps provide an explanation for his struggles. It's not yet clear whether the right-hander will miss more than the minimum of 10 days, but Paul Sewald will likely see increased save chances in Castillo's absence.
