The Royals opted against raiding its minor-league system as Monday’s trade deadline expired. They declined to restock it either.
Their only trade involved sending 27-year-old outfielder Brett Eibner to Oakland on Saturday in exchange for an outfielder one year younger: Billy Burns.
Unlike last year, when four promising left-handed pitching prospects were dealt to aid a World Series run, any reinforcements this year will come from the farm.
Three of their top 10 prospects rated by Baseball America prior to this season have already reached the majors — Raul Mondesi, Matt Strahm and Cheslor Cuthbert.

In 105 games this season with the Storm Chasers, Jorge Bonifacio has hit 16 home runs.
In 804 career games in the minors, Emilio Bonfacio has 13 homers. He also has 13 in the majors in 784 career games.

Right-hander Jake Junis had a season-high nine strikeouts Wednesday but allowed three runs in six innings of a 3-1 loss to Arkansas. He leads the Texas League with 117 strikeouts and is third with a 3.25 ERA.
Catcher Cam Gallagher is hitting .314 with three home runs in his last 10 games.
Class A Wilmington (Advanced)
First baseman Samir Duenez continues to thrive against Carolina League pitching with a .425 average in his last 10 games. A 20-year-old Venezuelan, Duenez is hitting .313 in 39 games with the Blue Rocks after hitting .272 in 68 games with Class A Lexington.
While he continues to strike out in an alarming 32.8 percent of his at-bats, center fielder Brandon Downes has made some strides offensively as of late. In his last 10 games, the former seventh-round pick is hitting .417 to raise his average to .241 this season. He also has eight strikeouts during that stretch, adding to his league-leading total of 141.

Cristian Castillo entered his first season of professional baseball in the United States as a relatively-unknown prospect. That may not be the case next year.
Castillo, a left-hander, pitched the first nine-inning shutout in the Appalachian League in three years Friday against the Pulaski Yankees. The 21-year-old from Monterrey, Mexico, needed just 94 pitches and struck out a season-high 11 batters while holding the Yankees to two baserunners in an 11-0 victory. He was named the Appalachian League’s pitcher of the week on Tuesday.
Castillo leads the league with a 0.91 WHIP and is ninth with a 3.07 ERA in 44 innings.
