Delgado arrived at Turner Field in time to be available to pitch out of the bullpen if necessary on Monday. The Braves are expected to promote two more pitchers once Gwinnett concludes its season on Monday. The likely candidates are Julio Teheran and Cory Gearrin.
Delgado went 4-9 with a 4.42 ERA in 17 starts for the Braves this season. Since being sent to Triple-A Gwinnett in late July, the 22-year-old right-hander has worked on gaining more consistency with his delivery.
The Braves could use Delgado as a reliever or possibly in a starting role if Tommy Hanson would continue to struggle. Ben Sheets, who is on the disabled list with right shoulder inflammation, is at least a week away from being able to start preparing for another potential start.
