Clevinger (knee) was activated from the 7-day injured list Sunday.
Clevinger landed on the injured list April 13 due to a right MCL sprain. He's since completed a rehab stint in the Florida Complex League, and it didn't take long to find his way into a game at Triple-A Indianapolis, where he allowed one hit and struck out two across a scoreless frame Sunday against Scranton/Wilkes-Barre.
