SURPRISE, Ariz. — The 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.
