Fedde will pitch in a bulk relief role Tuesday against Atlanta, James Fegan of SoxMachine.com reports.
Fedde picked up his first win of the season in a traditional start last week versus the Twins, but he will follow opener Brandon Eisert on Tuesday. The right-handed Fedde has collected a 4.94 ERA and 36:24 K:BB over 58.1 frames for the White Sox this season.
