	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). 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.
