The Indians got cash in Tuesday's deal.
Nix was claimed by Cleveland off waivers from the Chicago White Sox on June 24. He hit .234 with 12 home runs in 78 games for the Indians, splitting time between second base and third base.
The 28-year-old Nix has a career average of .215 with 26 homers and 48 RBIs in 218 career games for Colorado Rockies, White Sox and Indians.
Nix came to camp in competition for an infield spot, but hit only .176 and was beaten out of the starting job at third base by Jack Hannahan and lost the utility job to veteran Adam Everett.
