At the age of 27 years, 249 days of age, Alex Rodriguez becomes the youngest player in major league history to hit 300 home runs. The Ranger shortstop’s fifth inning three-run blast off Anaheim’s Ramon Ortiz in the Rangers’ 11-5 loss at Edison Field surpasses the mark established in 1935 by Hall of Famer Jimmie Foxx, who had accomplished the feat when being 79 days older than A-Rod.
