Miley will start the regular season on the disabled list, Roch Kubatko of MASN reports.
The left-hander is a bit behind the other pitchers after being hit in the shoulder by a comebacker earlier in the spring and then being sidelined by an illness. This will allow the Orioles to stash him on the DL until they need him to start on Sunday April 9 and carry some combination of 13 total relievers and bench players until then. Miley is expected to be completely healthy when that day comes around, but for the time being, he'll bide his time on the disabled list.
