Murray was outrighted to Triple-A Lehigh Valley on Friday.
Murray found success as a minor league reliever, but he could never translate it to the big leagues, forcing the Phillies to leave him off the 40-man roster heading into 2017. Murray is only 26 years old, so he could move up in the ranks if he posts another good season in the minors, although he'll just act as pitching depth for now.
