Edwards was reassigned to minor-league camp Saturday, Mark Zuckerman of MASNSports.com reports.
Edwards served as a non-roster invitee this spring after landing a minor-league deal with the Nationals in late February. However, he'll begin the season at Triple-A Rochester after he gave up five runs on five hits and three walks while striking out one in five innings across five appearances (one start) during Grapefruit League play.
