(CBS SF) -- A sports tickets website claims its latest rankings of Major League Baseball fans shows San Francisco Giants fans at number two in the league - and Oakland Athletics fans dead last.

Ticket broker TicketCity.com said on its 'Insided the Huddle' blog it ranked baseball teams' fan bases based on average attendance as a percentage of stadium capacity, average ticket resale price, annual team revenue, and number of social media followers as a percentage of its metro area population.

TicketCity.com also said it weighed attendance and ticket price more heavily, saying it felt it was more indicative of the fan base's enthusiasm.
