	Did you know that more than forty players have worn the number twenty-five for the Boston Red Sox — including Jack Clark, Denny Galehouse, Dizzy Trout and Tony Conigliaro. 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.
