The Diamondbacks announced today that left-hander Eduardo Rodríguez has been placed on the 15-day injured list, retroactive to May 15th, with left shoulder inflammation. Lefty Joe Mantiply has also been optioned to Triple-A Reno. To take those two spots, the club has recalled right-hander Scott McGough and selected the contract of righty Christian Montes De Oca. The 40-man roster had two vacancies due to Garrett Hampson and José Castillo being designated for assignment earlier this week. Per John Gambadoro of Arizona Sports 98.7 FM Phoenix, righty Ryne Nelson will take E-Rod’s rotation spot, taking the ball on Tuesday.

More to come.
