Marlins manager Don Mattingly said Tuesday that Lopez (shoulder) will initiate throwing off flat ground later this week, Christina De Nicola of MLB.com reports.
Lopez seems to have made some progress in his recovery from a right rotator cuff strain since being placed on the injured list a week and a half ago, but he still has several more hurdles to clear in the rehab process before the Marlins will consider reinstating him. At this point, fantasy managers shouldn't bank on Lopez returning until mid-August at the earliest, which may make it difficult to justify holding him in leagues with limited IL or bench spots.
