The Atlanta Braves announced Sunday that veteran reliever Aaron Bummer has been placed on the 15-day injured list due to shoulder inflammation and veteran starter Erick Fedde has been released.

To take their spots on the 26-man roster, the Braves added right-handed relievers Wander Suero and Hunter Stratton from Triple-A Gwinnett.

Bummer, 31, has fashioned a 3-2 record and 3.81 ERA in 42 appearances for the Braves. He has notched 51 strikeouts and 13 unintentional walks over 54 1/3 innings in his ninth big-league season.

Fedde, 32, appeared in five games after being acquired from the St. Louis Cardinals along with cash on July 27 in exchange for future considerations. The right-hander posted a 1-2 record with an 8.10 ERA in four starts and one relief outing for the Braves, which pushed his totals to a 4-12 record with a 5.76 ERA in 25 games this season.

Suero, 33, has pitched three relief outings for the Braves this year and allowed six runs in five innings. In 42 games for Triple-A Gwinnett, he has delivered a 1.39 ERA with 58 strikeouts and 13 walks over 45 1/3 innings.

Stratton, 28, has provided a 7.27 ERA in six games split between the Braves and the Pittsburgh Pirates. With Gwinnett, Stratton allowed just one run in 9 1/3 innings spread across seven appearances.
