CHICAGO -- The final few days before Tuesday's non-waiver Trade Deadline were somewhat quiet on the Royals' front, but general manager Dayton Moore said Tuesday afternoon he was overall pleased with the returns he received through the trades he began making last month.
"We like what we've been able to do and take advantage of trades that were available to us," Moore said, "for players that we acquired in the spring as we continue to improve and remake our organization."
The Royals may not be done, either. Pitchers Jason Hammel and Wily Peralta, and first baseman Lucas Duda also have expiring contracts and could be dealt if they were to clear waivers by Aug. 31. Moore said it's possible more deals could come, but he would not identify what players could be available.
"I guess it depends on how players perform and the needs of the [other] teams," Moore said. "This trading market for us began in June when we traded Jonathan Jay. It continued to progress when we traded Kelvin Herrera. And we acquired Brian Goodwin and then we traded Mike Moustakas.
"The trade market for us has been something we've been consistently involved with since June 10."
Moore's offseason goal was to restock the farm system as his team launches a rebuild, and he garnered several prospects through trades that have cracked the Royals' Top 30 prospects list per MLB Pipeliine.
Here's a summary of his deals with their Top 30 rankings:
• Jay traded to Arizona for pitchers Elvis Luciano (No. 24) and Gabe Speier.
• Herrera traded to Washington for third baseman Kelvin Gutierrez (No. 18), outfielder Blake Perkins (No. 16) and right-hander Yohanse Morel.
• Acquired Goodwin from Washington for Minor League right-hander Jacob Condra-Bogan.
• Traded Moustakas to Milwaukee for center fielder Brett Phillips (No. 8) and right-hander Jorge Lopez.
Moore specifically noted Perkins' development. Perkins has a .439 on-base percentage through 35 games at Class A Advanced Wilmington and has drawn 32 walks.
"We've been very proactive [in the trade market] because we needed to add prospects to our system at various levels," Moore said.
Royals call up O'Hearn
The Royals on Tuesday placed Goodwin on the disabled list, selected the contract of first baseman Ryan O'Hearn and transferred Cheslor Cuthbert to the 60-day disabled list to make room on the 40-man roster for O'Hearn.
O'Hearn, 25, found out Sunday he would be going to the big leagues.
"It's been a lot of years in the making," O'Hearn said. "A lot of hard work has gone into this."
O'Hearn was hitting .232 in 100 games at Triple-A Omaha with 11 home runs and 52 RBIs. But Royals manager Ned Yost said O'Hearn has been crushing the ball but not getting rewarded with positive results.
"I agree with that, for sure," OHearn said.
