Phillies placed LHP Kyle Backhus on the 15-day injured list, retroactive to April 27th, with left elbow inflammation.

The Phillies made the move in-between games of Thursday’s twin bill against the Giants. Trevor Richards was promoted from Triple-A Lehigh Valley to take his spot in the club’s bullpen. No word yet on the severity of the elbow issue for Backhus or how long he’ll be shelved for.
