The Athletics optioned Scott to Triple-A Las Vegas on Tuesday.
Scott was sent to the minors to make room on the 26-man active roster for Hogan Harris, who was recalled from Las Vegas and is expected to serve as a bulk reliever for Tuesday's game against the Royals. After getting called up from Las Vegas a week ago, Scott made two appearances out of the Oakland bullpen, tossing 2.2 scoreless frames.
