KANSAS CITY, Mo. (AP) -- The Royals have activated left-hander Tim Collins from the 15-day disabled list and optioned righty Aaron Brooks to Triple-A Omaha.
Collins had been out since April 7 due to a strained left elbow flexor.
Collins struck out 10 in four innings in three rehab appearances with Triple-A Omaha.
Brooks made his major league debut Saturday and gave up six runs on seven hits in two innings against Detroit.
