Royals pitching prospect Kyle Zimmer was placed on the disabled list Monday after experiencing shoulder soreness in his last start for Class AAA Omaha.
Zimmer lasted just one inning while starting against Round Rock last Thursday. He was making his second start for Omaha after opening the season with one start for Class AA Northwest Arkansas.
Royals assistant general manager J.J. Picollo told The Star on Tuesday that the club is evaluating Zimmer on a day-to-day basis.
“We will react to how he is feeling every day before we have a ‘return to action’ plan,” Picollo said in a text message.
