They include No. 5-ranked Jorge Bonifacio, an outfielder and the brother of current Royals infielder Emilio Bonifacio. The younger Bonifacio has played with Double-A Northwest Arkansas, Class A Wilmington and Rookie Surprise this summer, batting .299 with four homers and 52 RBIs in 87 games.

The other ranked player is No. 18, right-handed pitcher Jason Adam, who is 8-11 with a 5.45 ERA in 25 starts for Northwest Arkansas. He's a Kansas City area product, selected in the fifth round of the 2010 First-Year Player Draft from Blue Valley Northwest High School.
Among the other four players is left-handed pitcher Noel Arguelles, who was 1-8 with a 5.93 ERA in 25 games (11 starts) for Northwest Arkansas, but is now rehabbing with Surprise.
