Miller (elbow) is scheduled to make his next rehab appearance Monday for Double-A Jackson, the Associated Press reports.
Miller will be pitching on six days' rest after tossing five innings of one-run ball and striking out eight in his first rehab appearance for High-A Visalia on May 29. Miller threw 65 pitches in that outing, so he'll move up to the 75-to-80-pitch range Monday as he continues to build his arm back up following a 13-month layoff due to Tommy John surgery. The Diamondbacks will likely wait and see how Miller looks during Monday's outing before determining if another rehab start is necessary or if he's ready to return from the 60-day disabled list and rejoin the big club.
