Doolittle (shoulder) is making sock throws and has finally progressed in his rehabilitation, Jane Lee of MLB.com reports.

EDGE Analysis

Should Doolittle's shoulder respond well to the sock throws, he'll move onto the real thing and then onto a rehab assignment. At this point, he still isn't expected to return to Oakland until early June. Things will be touch and go until Doolittle proves his shoulder can handle game action, but if he comes back with the same kind of heat he showed when healthy (94.4 mph average fastball), he'll have a chance to work his way into save opportunities with the Athletics.
