Manager Don Wakamatsu said Moore and Wilson took early batting practice on Monday, and Bedard threw long toss in hopes of having a bullpen session with Moore on Friday. He added that Wilson could be sent out on a rehab assignment as early as the weekend if everything goes well.
Lowe, meanwhile, hasn't shown signs of recovery from the inflammation in his lower back that has held him out since early May.
"It just hasn't progressed. It's lingering," Wakamatsu said. "We've missed him quite a bit, obviously. He's a guy who did a lot for us last year, and we've tried to fill that gap and, unfairly, putting a lot of pressure on [Brandon League] in that situation."
He added that catcher Josh Bard is still experiencing tightness in his left calf. He'll be eligible to return from the DL on June 11.
