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.
