Murphy, 25, is hitting .366 with two home runs and seven RBI over his last 10 games for Triple-A Albuquerque.
Murphy is having a stellar 2016 campaign, slashing .322/.352/.648 with 17 home runs and 54 RBI in 71 contests. Nick Hundley and Tony Wolters have been adequate behind the plate at the big league level, but Murphy could get called up in September if the Rockies need an extra power bat.
