	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. The first player from the Angels franchise (they were the California Angels at the time) to wear the number twenty-five was Bob Perry. 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).
