Hated by his hometown fans (hey, it's Phillly, what do you expect) despite being one of the best players in the game during his first few years with the Phillies, Allen conducted his own personal home run derby for much of the '60s and early '70s. Considered one of the top 5 long distance sluggers in baseball history, he hit 18 homers entirely out of Connie Mack Stadium in Philadelphia. There's a reason Allen's not in the baseball Hall of Fame, and that's because a good proportion of the Baseball Writer's Association of America have their heads up their asses.
