I was saddened last month when I heard the news that Cleveland's Jacobs Field was being renamed Progressive Field. Not only is it impossible to make a cool nickname from Progressive ("The Prog" just sounds pretentious), but the move also means one more baseball stadium is falling to the corporate powers, who are slowly dominating the entire sports landscape. The ten teams below have all played in stadiums named after corporations. Identify the stadium the team hasn't played in.
