CLEVELAND -- The Royals' top pitching prospect, Kyle Zimmer, was placed on the disabled list on Sunday with right shoulder fatigue.
Zimmer, the club's No. 2 prospect overall and 60th-ranked prospect in all of Major League baseball according to MLBPipeline.com, has pitched 5 2/3 innings in the Minors this season between Class A Advanced Wilmington and Double-A Northwest Arkansas, allowing two runs (one earned) on four hits with 11 strikeouts in three starts.
The Royals' first-round Draft pick in 2012, Zimmer left his start for Northwest Arkansas on May 17 after only one inning due to shoulder fatigue.
