The Astros transferred Murfee (elbow) to the 60-day injured list Thursday, Matt Kawahara of the Houston Chronicle reports.
Murfee won't be able to pitch for the Astros until at least the final stages of the season after undergoing Tommy John surgery in July. His spot on the 40-man roster will be given to Miguel Diaz, who was claimed off waivers from Detroit in a corresponding move.
