EDGE Analysis

Hernandez has been slowed recently due to elbow discomfort, but he advanced to playing catch early in the week and was able to throw off a mound Wednesday. Manager Brandon Hyde was encouraged by Hernandez's successful throwing session. He'll play catch Friday and will be re-evaluated afterward, but Hyde isn't yet sure when Hernandez will be able to return to game action.
