Teheran had a trying season, posting a 5.08 ERA in 26 starts for Triple-A Gwinnett. But the talented 21-year-old right-hander provided the Braves some encouragement by allowing two earned runs or fewer in three of his final four starts.
After producing a 2.55 ERA in 25 appearances (24 starts) with Gwinnett in 2011, Teheran spent this season struggling with his mechanics. But he made some simple changes, such as raising his glove, and displayed a more fluid delivery as the final weeks of the season unfolded.
The Braves have no plans to add Jair Jurrjens to the roster this month. The former All-Star produced a 7.04 ERA in 10 starts with Atlanta this year and was placed on the disabled list on Aug. 1 with a strained right groin. He pitched 15 innings in the four rehab starts he made for Gwinnett over the past month.
