	Jim Thome wore number twenty-five since he first came up with the Cleveland Indians making him the franchise record holder for that particular number (Mike Garcia is second). 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? 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.
