The Pittsburgh Pirates have one of their bullpen assets back as reliever Colin Holderman has been activated off the 15-day injured list.
Fellow right-hander Cody Bolton was optioned to Triple-A Indianapolis to make room on the active roster.
Prior to landing on the injured list with right wrist inflammation, Holderman appeared in 26 games out of the bullpen. In 24.2 innings, Holderman is 0-1 with a 4.01 ERA, seven walks and 28 strikeouts.
Holderman has often served as the eighth-inning setup man for closing pitcher David Bednar.

With Indianapolis, Bolton is 1-2 with a 2.77 ERA across 18 appearances (one start).
