Morris will be called up to the Braves on Friday, Mark Bowman of MLB.com reports.
Morris, who was part of the deal coming back to Atlanta for Kelly Johnson on June 8, has pitched 22.2 innings for Double-A Mississippi. During that span, the 23-year-old owns a 2.78 ERA with 30 strikeouts and 17 walks. Morris will need to work on his command of the strike zone if he wants to be successful at the major league level.
