Last season, Spilborghs hit just .210 with three homers and 22 RBI in 98 games. His campaign was cut short due to plantar fasciitis in his right foot.
Spilborghs has a career .272 batting average with 42 home runs and 218 runs in 619 games, all with the Rockies.
The Indians also signed infielder Gregorio Petit to a minor league contract with an invitation to spring training. Petit, who missed the entire 2011 campaign with a knee injury, has hit .278 in 25 career games with Oakland.
