Morris was called up from Double-A Mississippi on Friday, David O'Brien of the Atlanta Journal-Constitution reports.
As expected, Morris is headed up to The Show for the first time this season. He's been a solid option from the bullpen with Mississippi, where he's posted a 2.78 ERA over 22.2 innings, striking out 30 batters in that time. He'll add depth to a subpar Atlanta bullpen that has a collective ERA of 3.98.
