The Royals built the core of their World Series championship club and back-to-back pennant winners largely from within. They excelled at finding talent with early first-round picks (Alex Gordon, Mike Moustakas, Eric Hosmer) and bargain international signings (Salvador Perez, Kelvin Herrera, Yordano Ventura). Last year, they put the finishing touches on their club by parting with most of their best young arms (Cody Reed, Sean Manaea, Brandon Finnegan) in deals for Johnny Cueto and Ben Zobrist.
Not that anyone is complaining in Kansas City, but those trades thinned out a farm system that won't offer much in the way of immediate help. While right-handers Kyle Zimmer and Miguel Almonte might reinforce the pitching staff in 2016, many of the Royals' best prospects are youngsters off to slow starts in the lower Minors.
• Royals' 2016 Top 30 Prospects list
Shortstop Raul Adalberto Mondesi is the jewel of the system but is still trying to find his footing offensively. Most of Kansas City's top position prospects follow his lead with a combination of interesting tools but unproven hitting ability. The Royals haven't had much success developing homegrown starting pitchers but hope to change that trend after taking high schoolers Ashe Russell, Scott Blewett, Nolan Watson and Foster Griffin the first two rounds of the last two Drafts.
Here are the players whose ranks changed the most from the 2015 preseason list to the 2016 preseason list.
