The Indians also said Sunday that they had designated infielder David Cooper for assignment.
The 28-year-old Sellers played 82 games for the Dodgers in the past three years, hitting .199 with three home runs and 17 RBIs. He split time at shortstop, second base and third base.
The 27-year-old Cooper finished last season in Triple-A for Cleveland. He hit .300 with four homers and 11 RBIs in 45 games for Toronto in 2012 before sustaining a serious back injury while diving back to first base on a pickoff attempt.
