The Indians on Saturday made a series of moves, highlighted by the placement of No. 5 starter Cody Anderson on the disabled list with a left oblique strain.
Anderson was terrific in his first four starts but has struggled in his last four with command issues.
The Indians also optioned down outfielder Tyler Holt.
In their places, the team is calling up relief pitcher Shawn Armstrong and outfielder Abraham Almonte. Almonte was acquired from the San Diego Padres at the July 31 non-waiver deadline in exchange for reliever Marc Rzepczynski.
