Philadelphia Phillies fans may be the most loyal. The St. Louis Cardinals appear most beloved by women. Fans of the Tampa Bay Rays may be the most devoted following a loss. But A's fans may be the most friendly and social, at least in terms of having the most friends on Facebook. And in a statistic that may cause Bay Area baseball fans to nod knowingly, fans of the Los Angeles teams, the Dodgers and Angels, are the most bereft of friendship among the 30 Major League teams.
