Ladnier has been offered another job in the organization.
"I thought Deric did a great job," Moore said. "His passion and energy toward that position and his loyalty to the Royals is certainly very much appreciated. At the end of the day, I just felt I wanted J.J. Picollo to oversee the Draft."
Picollo joined the Royals in 2006 as director of player development. On July 3, he was promoted to assistant general manager, scouting and player development.
Ladnier, a former player in the Royals' organization, returned to the team in 2000 as director of scouting. He had been a scout with the Atlanta Braves, where both Picollo and Moore worked before joining the Royals.
"I've been offered a position in the pro scouting department, and it's something I seriously need to consider. I've been here a long time and I'm very respectful and loyal to the organization," Ladnier said.
"They've been very good to me and my family. I've got nothing but good things to say about them."
Picollo now heads both the scouting and player development departments. He's assisted by Scott Sharp in player development, Steve Williams in scouting and baseball operations assistant Kyle Vena.
"We've got four people there, so we're well covered," Moore said.
Ladnier supervised the scouting and signing of players taken in the First-Year Player Draft. During his tenure the Royals' top choices included current big leaguers Zack Greinke, Billy Butler, Alex Gordon and Luke Hochevar.
