Edwards was recalled from Triple-A Iowa on Monday, Mark Gonzales of the Chicago Tribune reports.
Edwards was expected to continue his role as one of the Cubs' top setup men this season but allowed six runs while recording just five outs over his first four appearances as he struggled with his new delivery being deemed illegal. He should reclaim a high-leverage role now that he's back after he recorded a 2.16 ERA in 8.1 innings for Iowa. Dillon Maples was optioned in a corresponding move.
