Hernandez (ribs) will begin a rehab assignment with High-A Rancho Cucamonga on Tuesday, J.P. Hoornstra of the Southern California News Group reports.
A bout of left rib cage inflammation cost Hernandez nearly a month, but he's ready to return to action with the Dodgers' High-A affiliate, putting him on track for an early-August return to the big club. He will man center field in his first rehab game -- he made just four appearances there before hitting the DL (zero starts). Hernandez has played primarily in left field this season.
