Chen was officially called up by the Indians in anticipation of his start against Minnesota on Saturday. Anthony Swarzak was designated for assignment to make room for Chen, who earned a promotion by posting a 1.74 ERA, 0.71 WHIP and 23:3 K:BB in five starts for Triple-A Columbus to begin the year. Last season with Kansas City, Chen was knocked around to the tune of a 7.45 ERA in 48.1 innings, but he figures to hold down a starting job at least until T.J. House (shoulder) returns if he's even serviceable at the back of the Cleveland rotation.
