Murphy, 25, is slashing .296/.320/.640 with 13 homers and a 59:7 K:BB in 186 at-bats with Triple-A Albuquerque this season.
He is putting on quite the power display in the Pacific Coast League this year, although his 31.1-percent strikeout rate is troublesome. A catching prospect who can sustain a .335 ISO at Triple-A warrants monitoring in deeper formats, but it's unclear when the Rockies will be willing to recall Murphy, or if his hit tool will allow his impressive power to play against big league pitching.
