Lorenzen (hamstring) will be reinstated from the 15-day injured list to start Wednesday against the Nationals, Anne Rogers of MLB.com reports.
The right-hander has been out since late August due to a hamstring strain but will rejoin Kansas City's rotation after a pair of rehab outings. Lorenzen had a limit workload in both rehab appearances and will likely have some limitations Wednesday, which will be his final start of the regular season.
