The Oakland Athletics, commonly referred to as the Oakland A's, are a Professional Baseball team based in Oakland, California. They have several nicknames, such as the "White Elephants", the moniker given to them by New York Giant's manager John McGraw because of their less than stellar early seasons, and "the Swingin' A's" due to their success during the 1970's. Founded in 1901 as the Philadelphia Athletics, in 1955 they moved to Kansas City and remained there until they moved to Oakland in 1968. Soon after it was clear the Athletics would be a force to be reckoned with, winning 3 World Championships in a row, 1972, 1973 and 1974.
