Staumont was reassigned Wednesday to minor-league camp, Rustin Dodd of the Kansas City Star reports.
The Royals were evaluating Staumont as a potential relief option in the big leagues to open 2017, but it was never considered likely that he'd break camp with the club. He'll instead continue his development as a starting pitcher at the minor-league level, with Double-A Northwest Arkansas representing his likely destination to begin the campaign. The 23-year-old boasts excellent fastball and curveball offerings, but may need to improve his secondary stuff in the minors before getting a lengthy look as a starter in the majors.
