The Orioles placed Smith on the 15-day injured list Friday due to a groin strain, Andy Kostka of TheBaltimoreBanner.com reports.
Smith will be forced to sit for the rest of the regular season, and it's unclear whether the severity of the groin strain will keep him out of action for Baltimore's postseason run. Smith joined the Orioles in late June after being DFA'd and subsequently released by the Marlins. Working out of Baltimore's bullpen, Smith has posted a 5.74 ERA and 1.05 WHIP across 26.2 innings. Southpaw reliever Danny Coulombe (elbow) was activated from the 60-day IL in a corresponding move.
