Luis Avilan was promoted to Gwinnett to make roster room for Ben Sheets, but he was only there for a short while. In a tweet, he has announced he's heading to the big leagues. The corresponding move is not known, but Bowman speculates that Delgado will be sent to AAA due to the Braves not needing a 5th starter until after the ASB. However, the obvious move would be, after another poor outing, Jonny to AAA to get his stuff fully functional again.
Avilan is an interesing promotion because his numbers don't scream LOOGY but maybe someone knows something I do not.
