The Diamondbacks moved right-hander Trevor Cahill to the bullpen back in April and now they are prepared to eat the roughly $17 million remaining on his contract, as the team announced this evening that he has been designated for assignment to make room for J.J. Putz‘s return from the disabled list.

Cahill was acquired from the Athletics in December of 2011 for Jarrod Parker, Ryan Cook, and Collin Cowgill. The 26-year-old posted a 3.87 ERA in 57 starts and one relief appearance over his first two seasons in Arizona, but he was banished to the bullpen in April after just four ugly starts.
