Miller (groin) is in the lineup for Game 1 of High-A Charlotte's doubleheader Saturday, Bryan Levine of the Charlotte Sun reports.
Miller has been out since the first week of June with a groin strain, but is appearing in his first game since he went on the DL in early June. It is unclear how much Miller will play, but this is good progress for the infielder. The Rays haven't mapped out a timetable for Miller, but it appears as though he could make a return soon after the All-Star break.
