Miller (abdomen) went 0-for-3 with a walk in his first rehab game for High-A Charlotte on Wednesday, Marc Topkin of the Tampa Bay Times reports.
Miller's rehab assignment isn't expected to last very long, as he's been making steady progress over the last week-plus. The 27-year-old has been sidelined since May 16 with his injury, although he didn't officially go on the disabled list until two days later. Miller had snapped out of a 4-for-40 slump in the last game he'd played in, going 3-for-4 in a loss to the Indians.
