Morris was designated for assignment by the Braves on Saturday.
A roster spot was needed for the addition of Josh Ravin, whose contract was purchased from Triple-A Gwinnett on Saturday, and Morris was the corresponding roster casualty. The 25-year-old righty posted a 3.09 ERA and 53:23 K:BB across 46.2 innings with Gwinnett in 2017. He'll take a spin through waivers to determine where he'll open the 2018 campaign.
