Moore, who had stints in the Major Leagues the past four seasons, opened 2012 on the Mariners' disabled list before being claimed off waivers by the Royals on July 7. He appeared in four games for the Royals last season and went 2-for-11 with a home run and a double.
With regular catcher Salvador Perez on the bereavement list, the Royals promoted Moore from Triple-A Omaha to share the job with George Kottaras.
Moore hit .190 with two doubles, five homers and 12 RBIs for the Storm Chasers.
