Diekman (finger) has been able to throw from flat ground, but hasn't received clearance to throw from the mound, MLB.com's T.R. Sullivan reports.
Diekman is eligible to come off the DL on Friday, but there's been no speculation on if he'll be ready by then. A brief rehab assignment would seem to be needed, and Diekman would seem to be several days away at a minimum from beginning one at this point.
