Montgomery LHP James Houser has been placed on the 15 Day DL due to a left knee injury. Houser was pulled from his last outing on Thursday at Chattanooga after 69 pitches and five shutout innings because he couldn't surmount the dugout steps too well. Houser's DL placement is retroactive to May 30th. He is expected to serve the minimum time. To replace him, Montgomery has re-instated LHP Mike Wlodarczyk to the active roster.
