DJ Herz Injury: Diagnosed with elbow UCL sprain

Herz was diagnosed Tuesday with a left elbow UCL sprain, Andrew Golden of The Washington Post reports.

Herz's velocity was down this spring, which originally attributed to a "dead arm" phase. However, as it turns out, he's dealing with an injury that often requires season-ending UCL surgery, although it's not yet clear whether Herz might try the rest-and-rehab route first. At minimum, the lefty is likely to be out a few months, and in all likelihood, much longer.
