Pomeranz (shoulder) will begin a rehab assignment with High-A Stockton on Sunday, John Hickey of the Bay Area News Group reports.

Analysis:

Pomeranz advanced quickly through his throwing progression after being treated with a cortisone shot last week, going from playing catch Monday to a mound session Thursday. He'll cap his week off with a two-inning rehab outing with Stockton, though it's uncertain how many rehab appearances he'll make before returning from the DL.
