LOS ANGELES -- You can tell something has blossomed into a true social phenomenon around the Los Angeles Dodgers when Vin Scully comments on it.Two seasons ago, he discovered Twitter. As he read new outfielder Shane Victorino's tweet, he said, "The Dodgers received a Twitter and the Twitter read... Or, do you say, 'Twit?'"This season, Scully, 85, has, at times, turned his refined gaze to Yasiel Puig's bat flips. When Scully started broadcasting Dodgers games 64 years ago, a "bat flip" would have involved a DC comics superhero maneuvering to escape the Joker's henchmen, not something Jackie Robinson would have done before running the bases.
