Murdock was added to the active roster as Pittsburgh's 27th man for Saturday's doubleheader against Milwaukee.
Murdock has spent the entire 2026 campaign in the minors and owns a 3.45 ERA through 15.2 innings at Triple-A Indianapolis. He'll now join the big club for the first time this year to add depth to the Pirates' bullpen for the second game of the twin bill, and he'll likely be sent back down to Triple-A once Saturday's festivities are complete.
