The San Francisco Giants and the rest of the baseball world will finally find out whether a privately financed ballpark makes fiscal sense, as the team enters its first year of the post-Bonds era. According the San Francisco Chronicle, Giants’ ticket sales are already lagging compared to last year. Once impossible-to-get tickets are now even available at Costco. Though ever-optimistic team officials say they’re on track to sell three million tickets this year, at StubHub, an online ticket reseller marketplace, the overall value of Giants’ tickets is already down 25 percent. That all begs the question of whether the Giants can afford their privately financed stadium, with its estimated $20 million a year in debt payments, and stay afloat?
