The Cubs signed Pomeranz to a minor-league contract June 22.
Pomeranz was released by the Angels earlier this month after posting a 5.01 ERA and 16:12 K:BB across 23.1 frames. The left-hander quickly latched on with the Cubs and turned in a scoreless outing at Triple-A Iowa on Sunday. Pomeranz put up a 2.17 ERA and 57:15 K:BB over 49.2 innings for the Cubs last season and could get another chance with the big club if he finds his rhythm at Iowa.
