The Oakland Athletics began play as the Philadelphia Athletics as one of the original American League franchises. They won the World Series 5 times under famed manager Connie Mack and 9 AL pennants in total. In 1955, they moved to Kansas City and put together potentially one of the worst runs ever for a franchise, never finishing about .500 in 13 seasons and often finishing below .400. In 1968 they moved to Oakland where they still currently reside, winning 4 more World Series Championships. They've played the Cubs twice in the World Series, defeating them both times in 1910 and 1929.
