KANSAS CITY -- The Royals on Friday lost right-hander Mike Morin, who was claimed off outright waivers by the Mariners.
Kansas City had claimed Morin off waivers in September, and he was ineffective in six games with the club, posting a 7.94 ERA in six appearances.
Morin, 26, had signed a one-year deal with the Royals one week ago.
Kansas City's 40-man roster now sits at 38.
