Sampson (knee) completed his third rehab start at Triple-A Iowa on Saturday, tossing three innings and striking out two while allowing three earned runs on three hits and one walk.

EDGE Analysis

Sampson began his rehab program in the rookie-level Arizona Complex League on June 24 and has now made five appearances in total during the minor-league assignment, pitching to an 8.56 ERA and 1.39 WHIP in 13.2 innings. Since the Cubs don't appear to have a spot in the rotation available for Sampson, he'll likely remain on the farm for close to the full 30 days of the rehab assignment before being activated from the 60-day injured list. Sampson has three minor-league options remaining, so he could be optioned to Iowa once he's reinstated in order to continue making starts with the hope that a spot in the big-league rotation reopens at some point.
