Braves made LHP Dylan Lee and OF Forrest Wall their September callups

Lee, 29, has been a trusted reliever for Atlanta over the last two seasons when healthy. After putting up a 5-1 record and 2.13 ERA in 46 appearances last year, covering 50.2 innings, Lee was poised to repeat that excellence this season until "shoulder inflammation" put him on the 15-day IL in mid-May. Prior to the injury, Lee was 1-0 with a 3.10 ERA in 20.1 innings for Atlanta, mostly working in a single inning role but also serving as an opener in a bullpen game.   

However, his injury turned out to be more than just mild inflammation, as Lee was later moved to the 60-man injured list. He's been rehabbing in AAA Gwinnett, where he's pitched in seven games and holds a 1-1 record with four strikeouts in 7.1 innings. 

His return gives Atlanta a third left in the pen, joining AJ Minter and Brad Hand, and another option for medium-leverage relief. 

To make room on the 40-man roster for Lee, OF Sam Hilliard was transferred to the 60-day IL, ending his season. He went to the injured list in mid-July with a heel injury and re-injured it during his early-August rehab assignment in AAA Gwinnett. 

Also joining the roster is OF Forrest Wall. The 27 year-old, who joined Atlanta in the offseason on a minor league contract, joined the active roster in July for depth and got into parts of four games in Atlanta. He also registered his first big-league hit in hilarious fashion against the Mets before later being optioned back to AAA Gwinnett in mid August. 

Wall's role on this team is clearly pinch-running, as he's 261/337 in his minor league career and 52/60 this season for Gwinnett. He stole two bases in two pitches during his first big-league appearance, when inserted as a pinch-runner against Milwaukee in the 9th inning of a game soon after being called up.
