I guess because the Giants were in the region first? Alls I know is that the Giants blocked an an A's attempt to relocate to the South Bay, leaving Oakland with such unattractive options as: Oakland (current digs), Fremont, and Oakland (new ballpark? yeah, sure!) again. Given those choices, I'd just as soon move ninety minutes north to Sacramento. As the largest city in the Bay Area, San Jose would be a natural fit for either the ML A's, AAA Giants, or even the NFL 49ers (who are looking to move to Santa Clara, just on the SJ outskirts). And while I'm at it, the Raiders need to go back to LA, but the sweetheart deal they got from local lawmakers means that will not happen (Raider games rarely sell out, meaning no local telecast, but Al Davis is reimbursed by the city for all seats not sold).
