Miller is scheduled to start Monday's game against the Astros, though he'll remain on a pitch count, Martin Gallegos of MLB.com reports.
Miller made his first big-league appearance since May last Wednesday after being on the shelf with an elbow sprain, and he'll now move back into the rotation. The rookie right-hander threw just 27 pitches in that outing, so his pitch count is likely to be well below that of a typical starter. Miller could be deployed as more of a piggyback pitcher in front of Ken Waldichuk, who would be available to pitch Monday on five days' rest.
