The Royals placed Minor on the 10-day injured list Wednesday with left shoulder impingement syndrome, Lynn Worthy of The Kansas City Star reports.

EDGE Analysis

Minor's move to the IL explains why he was scratched prior to his scheduled start Wednesday against the Athletics for a previously unknown reason. Manager Mike Matheny hasn't commented on the severity of Minor's shoulder issue, but the veteran southpaw seems likely to be shut down for the season with just two and a half weeks left to go. Kansas City has been running out a six-man rotation lately, so Matheny may just scale back to five starters rather than immediately appointing a replacement for Minor.
