July 8, 1956: In the first game of a doubleheader, Willie Mays was one of three New York Giants to hit two home runs, winning the game over the Pittsburgh Pirates, 11-1. Congratulations were in order, but the Giants lost the second game, 5-2, at the Polo Grounds in Upper Manhattan. Before long, the Giants, including Mays, were relocated to San Francisco, and later still, a new team — whose logo and colors were an amalgamation of the the Giants and the Brooklyn Dodgers — represented New York, the Mets.
