Stites (elbow) has been activated from the disabled list and demoted to Triple-A Reno, Jody Jackson of Fox Sports Arizona reports. The injury bothered him since early spring training, and the returns on his rehab assignment were a bit of a mixed bag (five strikeouts, but two runs in 1.1 innings). He'll go get right in Triple-A, and if he shows promise there, could become part of what's been an embattled Arizona bullpen.
