As baseball fans know, the Billy Beane-built Oakland A's teams from the 'Moneyball'-era never won the World Series. (Spoiler alert? The A's topped out at the American League Championship Series in 2006.) That doesn't mean the team wasn't successful, of course, though it does leave the upcoming film 'Moneyball' without a traditional happy ending. Which is sorta why Bennett Miller wanted to make it in the first place.
