After hearing he made the team, Butler was in shock, according to KansasCityRoyals.com.
"I'm very humbled and very honored, especially at our own ballpark and being able to play in front of the home crowd," Butler said. "My family is going to come out to see me play and do all the activities on the field. I'm just speechless right now."
Butler is off to a strong start this season. He has 16 home runs, 13 doubles and 48 RBIs with a .297 batting average.
The Royals designated hitter also said that he would be interested in participating in the Home Run Derby if Robinson Cano selected him.
