Kopech (forearm) threw off a mound Saturday to a standing catcher, David Vassegh of AM 570 LA Sports reports.

EDGE Analysis

While it wasn't a full-fledged bullpen session, Saturday marked the first time Kopech had done any sort of mound work since the start of spring training. The 28-year-old righty has been behind schedule since the start of camp due to inflammation in his right forearm, and there's no guarantee he'll be ready to go when the Dodgers begin their domestic schedule March 27.
