Royals demote Lucas Erceg and promote Carlos Durán from Omaha

The Kansas City Royals have optioned reliever Lucas Erceg to Omaha, citing his struggles with command. Erceg has posted a 6.23 ERA this season, contributing to the team's second-worst bullpen ERA in MLB. He has allowed 26 runs in his last 27 appearances. Carlos Durán, acquired from the Dodgers, will replace him after a solid performance in the minors, where he recorded a 3.15 ERA in 40 games. Durán's fastball reaches 96 mph, and he has potential as a bullpen asset.
