Arizona: SS Stephen Drew (ankle) slid in pregame work Saturday afternoon, the first time he had done any sliding since sustaining a season-ending fractured ankle and ligament damage when his spikes caught in the dirt on a play at the plate on July 20, 2011. Drew was scheduled to play nine innings in extended spring training games Tuesday and Thursday. ... CF Chris Young (shoulder) was scheduled to begin a three-game rehab assignment at high-A Visalia (Calif.) today and possibly rejoin the D-backs later this week.
