Prior to the roster deadline today, the Royals have added three players to their 40-man roster, to protect them from being eligible for the rule 5 draft. Those players are right handed pitchers Josh Staumont, Scott Blewett, and Arnaldo Hernandez.
At 25 years old, Staumont is somewhere among the Royals top 20 or so prospects, depending on what you make of him, his stuff, and his future (which is dependent on the first two). Armed with a fastball that clocked 103 MPH in college (likely on a gun that ran hot) and a big curveball, Staumont might convince you he pitches with his eyes closed sometimes.
