And then there was one.
The Royals are down to one affiliate competing in the playoffs after Burlington lost in the rookie-level Appalachian League championship series on Wednesday to the Johnson City Cardinals.
The Class AA Northwest Arkansas Naturals beat the Springfield Cardinals in their playoff opener.
Here’s a quick rundown of the Royals’ farm system:
Class AAA Omaha
Record: 58-82 (season ended Monday).
Top hitter: Third baseman Hunter Dozier hit .294 with 15 home runs, 36 doubles and 54 RBIs in 103 games.
Top pitcher: A case could be made for starter Luke Farrell (6-3, 3.76 ERA in 91 innings), but reliever Brooks Pounders gets the call here. Pounders, a 25-year-old right-hander, made his big-league debut this season after a successful transition to the bullpen. Pounders went 5-3 with 90 strikeouts and a 3.14 ERA in 80 1/3 innings pitched with Omaha.
Class AA Northwest Arkansas
Record: 65-75 overall (36-34 and first place of the Texas League North Division in the second half).
Playoffs: Beat Springfield 9-6 Wednesday in the first game of a best-of-five semifinal. Midland leads Corpus Christi 1-0 in the other semifinal.

Class A Wilmington (Advanced)
Record: 54-84 (season ended Monday).
Top hitter: First baseman Samir Duenez (.300 average, 42 RBIs in 56 games) excelled in Lexington and Wilmington this season.
Top pitcher: Tough-luck righty Zach Lovvorn (2-15, 3.95 ERA in 127 2/3 innings) had a solid season despite being tied for the third-most losses in minor-league baseball in 2016.
