Seuly Matias

In a system lacking in toolsy, high-pedigree position players, Matias is an outlier. One of the top prizes in the 2015 international signing class, Matias signed with the Royals for a $2.25 million bonus and made his stateside debut in 2016. While he currently has the speed for center field, his size (6-foot-3, 200 pounds and growing), plus power and plus arm make him an obvious long-term fit in right field. He tied for the Arizona League lead with eight home runs -- an impressive feat for a 17-year-old slugger. The power is clearly real, and he can already hit balls out to all fields. There are some obvious flaws in his game, but it's so early in the developmental process that it's hard to nitpick too much. He posted a 36.9 percent strikeout rate but also walked 11.1 percent of the time, which is rare for any 17-year-old. Matias is forever away, and there is plenty of risk, but he has a higher ceiling than any hitting prospect in the Royals' system.
