Fedde will server as the White Sox's primary pitcher in Friday's contest against the Tigers, LaMond Pope of the Chicago Tribune reports.
Chicago will deploy a lefty opener in Brandon Eisert before turning things over to the righty Fedde to handle the bulk of the innings. Fedde's last outing was as a bulk reliever and it didn't go well, as he was bludgeoned for eight runs on 10 hits and two walks over 3.1 innings in a loss to the Giants.
