The KC Royals Double-A affiliate, the NW Arkansas Naturals, just announced their Opening Day roster.
The youngest being top prospect Raul Mondesi (19) and the oldest being catcher Anderson De La Rosa (30).
Here is the Naturals roster for Opening Day (which is Thursday in Midland):
Pitchers: Miguel Almonte, Brandon Finnegan, Glenn Sparkman, Jonathan Dziedzic, Andy Ferguson, JC Sulbaran, Daniel Stumpf, Malcom Culver, Aroni Nina, Mark Peterson, Reid Redman, Sam Selman, and Ali Williams.
Catchers: De La Rosa and Santiago Nessy (neither were in the organization before).
Infielders: Balbino Fuenmayor, Alex Liddi, Angel Franco, Dusty Coleman, Mondesi, and Hunter Dozier.
Outfielders: Lane Adams, Jorge Bonifacio, Mike Bianucci, and Terrance Gore.
Of the 25 on the Naturals roster, seven were not in the Royals organization in 2014. Coleman, Bianucci, and De La Rosa all played in the Texas League last season.
When I talked to Vance during spring training, he was hoping for a better season than in 2014. He had a young team last year and a bunch of the players have matured. Now he has quite a few minor league veterans.
The catching group is interesting considering Zane Evans started the three Double-A games I saw in spring training, with Pedro Gonzalez backing him up. I will have to wait until tomorrow to find out where these two end up.
Others missing from the Royals upper level rosters are catchers Parker Morin and Micah Gibbs, relievers Angel Baez, Matt Murray, and Andrew Triggs, and outfielder Ethan Chapman (I already mentioned John Lamb, Brian Fletcher, and Casey Kotchman in my Omaha roster post).
