Braves placed LHP Aaron Bummer on the 15-day injured list with left shoulder inflammation.
No word yet on how much time Bummer figures to miss, but shoulder ailments typically lead to extended absences, which puts his season in jeopardy. The 31-year-old southpaw has posted a strong 3.81 ERA across 54 1/3 innings (42 appearances, two starts) during his second season in Atlanta.
