Kowar will draw a second straight turn through the Kansas City rotation in Tuesday's game at Baltimore, Anne Rogers of MLB.com reports.
After joining Kansas City when the roster expanded from 26 to 28 men, Kowar slotted back into the team's rotation. He delivered a quality start Sept. 1 in a no-decision versus Cleveland, striking out six over six innings while giving up two runs on five hits and three walks. The Royals will reward Kowar with another start as a result, and he should hold down a spot in the team's six-man rotation until one of Brad Keller (lat) or Jakob Junis (shoulder) returns from the injured list.
