	The most recognizable Detroit Tiger to wear the number twenty-five was probably Norm Cash (who wore it from 1960 through 1974), but did you know that Hall of Famer Larry Doby also wore it during his single season with Detroit? The first player from the Angels franchise (they were the California Angels at the time) to wear the number twenty-five was Bob Perry. Future Hall of Famer Sammy Sosa is best known for wearing number twenty-one; however, when the young slugger played for the Chicago White Sox (1989-1991) he only wore number twenty-five.
