Stephen Drew (ankle) will play nine innings Tuesday and Thursday in extended spring training and continues to work his way toward a Minor League rehab assignment.
"It's still not that close, but if he gets through this next week OK, we are going to look to advance him to a different level of competition," D-backs manager Kirk Gibson said.
Center fielder Chris Young (shoulder) will begin a three-day rehab assignment, likely with Class A Visalia on Monday.
D-backs right-hander Daniel Hudson, who faced hitters Friday for the first time since going on the disabled list on April 21 with a right shoulder impingement, remains on track. He will throw a bullpen session Monday and pitch Wednesday in an extended spring training game. He could start a rehab assignment five days later with Triple-A Reno, Gibson said.
