Bieber (shoulder) will make a rehab start for Double-A Akron on Sunday, Zack Meisel of The Athletic reports.
Bieber has been out with a shoulder strain since mid-June. He threw 2.2 innings in a rehab start Tuesday and is expected to throw four in his second rehab appearance. If that's the final rehab start he needs, he could return on a reduced pitch count near the end of next week. It doesn't look as though he'll have time to make more than two major-league starts before the end of the season.
