 That historical rivalry was revisited when the Giants beat the Cubs in the 1989 NL playoffs, in their tiebreaker game in Chicago at the end of the 1998 season, and on June 6, 2012 in a "Turn Back The Century" game in which both teams wore replica 1912 uniforms.The Giants-Dodgers rivalry is one of the greatest and longest-standing rivalries in team sports, and has been regarded as the most intense in American baseball.The Giants-Dodgers feud began in the late 19th century when both clubs were based in New York City, with the Dodgers based in Brooklyn and the Giants playing at the Polo Grounds in upper Manhattan.
