Murray was optioned to Triple-A Lehigh Valley following Thursday's game, Ryan Lawrence of The Philly Voice reports.
The Phillies' bullpen has been overworked over the past few days due to a number of blowout losses, so the organization optioned Murray back to Triple-A with the intention of recalling a fresh arm. Murray pitched for the third consecutive night Thursday, working two scoreless innings after starter Aaron Nola was tagged for six earned runs in just 3.0 innings. The Phillies will recall a bullpen arm Friday to take Murray's spot on the active roster.
