Cleveland optioned Morris to Triple-A Columbus on Friday, Zack Meisel of The Athletic reports.
Morris has surrendered six earned runs on 10 hits and six walks in eight major-league innings this season, which works out to a 6.75 ERA and 2.00 WHIP. Waiver additions Reynaldo Lopez and Matt Moore are joining the Guardians' bullpen Friday, while Hunter Gaddis also gets the boot.
