Almanzar signed a minor league contract with the Tigers on Tuesday, Matt Eddy of Baseball America reports.
The 26-year-old, who has never appeared in the majors, batted .241/.297/.380 with 10 home runs and 41 RBI across 410 at-bats with the Orioles' Triple-A affiliate last season. Although he has shown improvement across the board, Almanzar will likely stay in Triple-A another year.
