Claimed off waivers from the Mariners in February, Hulett hit .111 in 15 games for the Royals. He hit .291 with 11 homers, 53 RBIs and 27 doubles for Triple-A Omaha in 2009, his sixth season in the Minors.
Hulett represented the U.S. in the Baseball World Cup in August, hitting a home run in the gold-medal victory over Cuba.
The Royals also placed right-handed pitcher Julio Pimentel on waivers for the purposes of his unconditional release. He is now a free agent.
