Those came in advance of the crowning moment, when the club reached an agreement with first-round pick Bubba Starling, a power-hitting outfielder.
Right-handed pitcher Bryan Brickhouse, the Royals' No. 3 selection, is from The Woodlands (Texas) High School, where he had a 7-2 record, 1.08 ERA and 129 strikeouts in 72 innings. He has a power arm with a fastball in the 90- to 95-mph range and a good curveball.
Brickhouse received a $1.5 million signing bonus.
The Royals' No. 4 choice, right-handed pitcher Kyle Smith, is from Santaluces High School in Lantana, Fla., where he was 9-1 with a 0.40 ERA and 116 strikeouts in just 69 1/3 innings. He signed rather than take a baseball scholarship at the University of Florida.
No. 5 pick Patrick Leonard is a third baseman who led St. Thomas High School of Houston to the Texas state 5-A private school title this year. He had a baseball scholarship to the University of Georgia.
Also signed by the Royals:
Shortstop Jack Lopez, the 16th-round pick from Deltona (Fla.) High School. A nephew of former Royals shortstop Onix Concepcion, he passed on a scholarship to the University of Miami.
Right-handed pitcher Jake Junis of Rock Falls (Ill.) High School, the 29th-round pick, who passed on a scholarship to North Carolina State University.
Right-handed pitcher Christian Binford from Hagerstown, Md., and Mercersburg (Pa.) Academy, the 30th-round choice who had a scholarship to the University of Virginia.
MLB.com has confirmed that Smith's signing bonus is for $695,000, Leonard's is $600,000 and Junis' is $675,000.
