Royals' Jakob Junis: Back tightness deemed minor

Manager Mike Matheny said Tuesday that Junis' back tightness is not serious, Jeffrey Flanagan of MLB.com reports.

The Royals are being cautious with Junis and expect him to throw on the side during the upcoming days. The 27-year-old threw an efficient inning with two strikeouts during his spring debut Thursday and will likely miss limited time before returning to the bottom half of the Kansas City rotation for the remainder of camp.
