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