The Cubs claimed Herget off waivers from Atlanta and optioned him to Triple-A Iowa on Friday, Maddie Lee of the Chicago Sun-Times reports.
Herget made eight appearances for Atlanta and posted a 4.38 ERA and 1.30 WHIP across 12.1 major-league innings before being designated for assignment. After being scooped up by the Cubs, Herget will take over a spot on the organization's 40-man roster, but he'll head to the Triple-A level for now.
