Lorenzen (hamstring) will continue his rehab assignment Friday with Triple-A Omaha.

The right-hander gave up three runs over 1.2 innings during his first rehab outing Tuesday with Double-A Northwest Arkansas, and he'll follow that abbreviated appearance with another start Friday. Lorenzen is working his way back from a Grade 2 hamstring strain he sustained in late August, and it's unclear if he'll require another rehab outing before being activated from the injured list.
