If you follow baseball, you surely know Billy Beane, the architect of the Oakland Athletics, the guy who Brad Pitt portrayed in the film version of "Moneyball." But the casual baseball fan probably as isn't familiar with the story of Billy Bean — note the spelling difference — which is now getting the documentary treatment from MLB Network . Bean played six season in the 1980s and 1990s, an outfielder for the Detroit Tigers, San Diego Padres and Los Angeles Dodgers. He had an unspectacular playing career, but his story is worth telling for personal reasons — he's one of only two current or former MLB players to come out as gay.
