Rasmus (groin) is on the 7-day disabled list with Double-A Montgomery, Rashad Snell of Alabama News reports.
The right-hander was sidelined for much of spring training due to this groin issue, and it doesn't appear to have improved much since the beginning of March. It's unclear how long he'll remain out, but a firmer timetable should come forth as he progresses in his recovery program.
