	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. 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). 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.
