According to an annual fan cost index, the beer you buy at AT&T Park is baseball's most expensive suds. NBC Bay Area has the full report: "That $8.75 you pay for a 20-ounce beer is more than any other team in baseball in America charges -- by a full 75 cents." Coming in at second place was beer at Tampa Bay Rays' Tropicana Field in Florida, who charge $8 for a 20-ounce beer. But the beer that wins the title of worst deal? NBC Bay Area gives that distinction to Boston's Fenway Park, where "7.25 only buys you a 12-ounce beer."
