Earlier today the news broke that Jose Berrios was being called up but the corresponding move was not announced. It was guessed that it would be a starter heading to the disabled list, specifically Ervin Santana, Kyle Gibson or Tyler Duffey.
It turns out that two starters will be placed on the disabled list. Ervin Santana is dealing with back spasms and Kyle Gibson has a shoulder strain. The pair will join Trevor Plouffe and Glen Perkins on the shelf.
