Diaz (leg) was recalled from Triple-A Indianapolis and placed on the 60-day DL on Tuesday.
This amounts to nothing more than a paper move to free up a spot on the 40-man roster. Diaz had already been ruled out for the remainder of the season after undergoing surgery to clean up a bacterial infection in his leg. The 25-year-old also missed significant time with elbow troubles and hit just .266/.289/.298 in 25 games with Indianapolis.
