SURPRISE, Ariz. – The Kansas City Royals have optioned three of their top prospects, infielder Hunter Dozier and outfielders Jorge Bonifacio and Bubba Starling, to Triple-A Omaha as they begin paring their roster

Kansas City announced the series of roster moves Friday.

Dozier is a power-hitting third baseman who has been working at other positions as the Royals try to get his bat into the lineup. But he may ultimately remain at third base and take over next season for Mike Moustakas, who is eligible for free agency.

Bonifacio is a speedy outfielder and Starling one of the team's best defensive prospects.

The Royals also optioned right-hander Andrew Edwards, catcher Cam Gallagher and infielder Ramon Torres to Omaha, leaving them with 45 players in big league camp.

ROYALS 8, BREWERS 5: Nathan Karns, acquired from the Mariners in a trade for Jarrod Dyson, pitched four innings and gave up three runs on seven hits. Christian Colon homered and Alex Gordon had two hits and two RBIs.

Ryan Braun hit his first spring homer for Milwaukee. Jimmy Nelson worked into the fourth inning, giving up five runs on six hits, but striking out six.
