Atlanta activated Young (elbow) from the 60-day injured list Friday.
Coming back from Tommy John surgery, Young was sharp in five rehab outings, posting an 8:4 K:BB while yielding just one hit and one unearned run over 5.1 innings. With a career 78:25 K:BB over 60.2 frames, Young could provide a nice boost to the Atlanta bullpen in a low-leverage role.
