Boxberger (back) is scheduled to throw batting practice sessions next Monday and Thursday at High-A Charlotte, Roger Mooney of the Tampa Bay Times reports.
Boxberger's bullpens have gone well, allowing him to take the next step in his rehab. If the pair of batting practice sessions also go off without a hitch, the veteran reliever would presumably be slated for some rehab appearances as the final step before his 2017 debut with the big-league club.
