The Royals optioned Rave to Triple-A Omaha on Tuesday.
Rave got his first taste of major-league action last season and posted a .196/.283/.307 slash line with four homers, 14 RBI, 18 runs and seven stolen bases over 175 plate appearances. Kansas City revamped its outfield during the offseason, leaving Rave without a spot on the season-opening big-league roster.
