Hernandez threw a clean inning in rehab outing for High-A Visalia on Saturday, striking out one. Hernandez reportedly was hitting 93-95 mph with his fastball. He will need at least a couple of more rehab outings before the D-Backs will bring him back, but with Addison Reed being moved out of the closer role there is an opportunity for Hernandez to be in the mix for save chances, if he proves healthy and effective.
