The San Francisco Giants are an American professional baseball team based in San Francisco. The Giants compete in Major League Baseball as a member club of the National League West division. Founded in 1883 as the New York Gothams, and renamed three years later the New York Giants, the team eventually moved to San Francisco in 1958. The franchise is one of the oldest and most successful in professional baseball, with more wins than any team in the history of major American sports. The team was the first major-league organization based in New York City, most memorably playing home games at several iterations of the Polo Grounds. The Giants have played in the World Series 20 times, an NL record. The Giants' eight World Series championships are second-most in the NL and fifth-most of any franchise. The Giants' rivalry with the Los Angeles Dodgers, one of the longest-standing and most famed rivalries in American sports, began in New York and continued when both teams relocated to the West Coast in 1958.
