Murphy, 26, was expected to play a significant role behind the dish for the Rockies after a promising 21-game stint in 2016. But he was sidelined in camp with a fractured forearm and has yet to appear at the major league level in the current season.
Colorado will hope for a boost on offense by swapping in Murphy. He has been a steady producer at the plate as a professional, including his rehab time in 2017. Through 31 plate appearances at Triple-A, Murphy owns a .414/.419/.724 slash — though he has also gone down on strikes nine times.
As for Hanigan, his consent was required for the move given his lengthy service time. Playing a supporting role to Tony Wolters, the 36-year-old has produced a .256/.304/.395 slash in his 46 trips to the plate on the year. He’ll wait in Triple-A to see if a need arises.
