The Orioles reinstated Enns (foot) from the injured list Saturday.
Enns made five rehab appearances in Triple-A after landing on the injured list with a foot infection, allowing four earned runs on five hits and no walks while striking out 10 batters over 6.1 innings. He'll presumably claim a middle-relief role in Baltimore's bullpen now that he's healthy, and the Orioles will send Tyler Wells to the minors to make room for Enns on the active roster.
