The Orioles purchased Yacabonis' contract from Triple-A Norfolk on Sunday, Roch Kubatko of MASN Sports reports.
After suffering an embarrassing 16-3 loss to the Yankees on Saturday, the Orioles elected to overhaul their bullpen, adding Yacabonis and Logan Verrett from Triple-A while dropping Edwin Jackson and Stefan Crichton. It's the first big-league promotion for Yacabonis, who supplied a 0.90 ERA and 1.03 WHIP and collected seven saves in nine chances over 30 innings with Norfolk. With few reliable healthy options in the bullpen behind closer Brad Brach and setup man Mychal Givens, Yacabonis could quickly vault up the depth chart in Baltimore.
