Hernandez (ribs) will have his rehab moved to Double-A Tulsa on Wednesday, Ken Gurnick of MLB.com reports.
He has logged two rehab games in the Arizona League and two rehab games in the California League and has now been transferred to a more challenging environment. There still isn't a specific timetable for his return, but an early-August activation seems likely at this point. Upon his activation he will return to a part-time role with the Dodgers.
