Guthrie will be moved back into the starting rotation, Andy McCullough of the KC Star reports.

EDGE Analysis

The Royals moved Guthrie to the bullpen last month after a string of sub-par starts, but with Danny Duffy struggling of late, Guthrie will re-enter the rotation for the final few weeks of the regular season. It's unclear exactly when Guthrie will make his next start, though it will likely be Tuesday when the Royals host the Mariners. Guthrie has not been overly effective out of the pen over the last month, allowing six earned runs on eight hits over 11.1 combined innings of long relief.
