	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. 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). Jose Cruz of the Houston Astros had his number twenty-five retired on October 3, 1992, and became the first Major League player with that particular retired number.
