The Orioles selected Suarez's contract from Triple-A Norfolk on Tuesday, Roch Kubatko of MASNSports.com reports.
Suarez will provide a much-needed fresh relief arm after the Orioles' bullpen had to cover 4.1 innings in Monday's blowout loss to the Rays. He's posted a 3.45 ERA and a 9:9 K:BB in 15.2 innings with Baltimore this season.
