Reds' Robert Stephenson: Back on active roster

Stephenson (back) was activated from the 10-day injured list Monday.

The right-hander made just one appearance in late July before a back strain forced him to the IL. The 2011 first-round pick fizzled out as a starter but found his niche in relief last year, posting a 3.76 ERA, 1.04 WHIP and 11 holds. He finished third among qualified relievers in swinging-strike rate and should eventually regain a prominent spot near the back of the Reds' bullpen.
