Royals pitching prospect Kyle Zimmer is expected to resume his throwing program around July 15, the Kansas City Star reports.

Zimmer, the No. 5 overall pick in the 2012 rookie draft, was shut down at the end of May due to a muscle strain in the back of his right shoulder. His winter throwing program also came to an abbreviated end due to shoulder soreness, and he missed spring training with biceps tendinitis. If his recovery goes well, the Royals plan to give Zimmer some work in the Arizona Fall League.
