Smith (shoulder) was activated from the 7-day injured list Sunday.
Smith made two rehab appearances at High-A Winston-Salem earlier this month, where he allowed three runs on four hits and two walks while fanning eight over 4.2 innings. He was activated from the injured list Sunday and made a start for Triple-A Charlotte later that same day, surrendering one run on three hits and one walk while collecting five strikeouts across four frames.
