The Pirates recalled Murdock from Triple-A Indianapolis ahead of Wednesday's doubleheader versus the Yankees.
Pittsburgh has designated Murdock as its 27th man for the twin bill, so he'll likely be headed back to Indianapolis on Thursday. The 27-year-old righty has turned in a 3.24 ERA, 1.11 WHIP and 26:5 K:BB in 16.2 innings out of the Triple-A bullpen this season.
