The Indians set their roster for Opening Day Monday in Oakland with several roster moves.
The contracts of right-hander Scott Atchison, designated hitter/first baseman Jason Giambi and outfielder Nyjer Morgan were purchased from Triple-A Columbus. The three had been in camp on minor league deals.
Center fielder Michael Bourn and Giambi were placed on the 15-day disabled list, retroactive to March 21.
To make room on the 40-man roster, right-handers Preston Guilmet and Frank Herrmann and lieft-hander Colt Hynes were designated for assignment.
Outfielder Matt Carson and infielder Ryan Rohlinger were reassigned to minor league camp.
