In the 1950s, three legends were present in one city: New York. All represented different teams. There was Mantle with the Yankees, Mays with the Giants, and Snider with "Dem Bums." These team were dominant in this time. They had a total 9* World Series triumphs, 17* appearances, and 7* match-ups between each other from 1947 (Duke's first year) to 1957 (Giants' last year in New York).
Has any other city had such dominant teams and/or players that could match this?
